I'm Sorry, Dave. I'm Afraid I Can't Do That (Me and Autopilots)

Somewhere over the Central Valley...


I get an unexpected extra day off work over the 4th of July weekend, so I do a sobering but weirdly-pleasant IFR-in-VMC flight on my own to Stockton (KSCK), where I do the ILS RWY 29R with the missed as published, all hand-flown (for fun!) under the guidance of the G1000's flight director, but not under the Cone Of Stupidity or in actual, of course. Following that, a leisurely VFR-only flight back to Hayward (KHWD) including a diversion to Livermore (KLVK) for some touch-and-goes on runway 25L there (and what a pleasure that always is!).

I’m rusty as hell on real-world IFR procedures, and it shows — and it’s the reason I do this flight on a real IFR flight plan but in clear VMC, and to a destination and along a route and including an approach all of which I'm familiar with. I can barely remember how to get my clearance on the ramp at Hayward (which takes me all of ten seconds to get right, but still…), I bungle several radio calls, I input the wrong heading on a vector, I can’t initially get the autopilot to do the right thing with altitudes (below), and I ask for the wrong approach at Stockton. I make it sound terrible, but really, nothing was so bad that I busted any limits or anything, as far as I know (the heading was 10 degrees off and I caught it quickly, for example), but it still left me seriously glad I did this today rather than in IMC. After this flight, I actually feel like I could do it for real again now; as always, it's all about complexity management.

The autopilot? A real brain failure on my part here, as usual. Initially on the departure out of Hayward I can’t seem to get it to do altitude arming using what I think is the “obvious” way, but it’s another of those weird problems I have with altitude arming on both this (the Garmin GFC 700) and the older non-integrated one in the other DA-40’s: I confuse arming and capture, and somewhere over the Central Valley on my way to Stockton I feel like kicking myself when I realise (with a few seconds of metaphorically standing back and thinking) what I should be doing (that “ALT” button in both cases means “capture / hold”, not arm, unfortunately). The good news here is I didn't obsess about it, or spend a lot of time debugging it on-the-fly (as it were) — I just shrugged and kept hand flying. The autopilot in the DA40 is a technological wonder — and increases single-pilot IFR safety an order of magnitude over hand-flying, and it’s more obvious in use than the other models — but it’s still a bit intimidating when it sits there (silently) doing the autopilot equivalent of “I'm sorry, Dave. I'm afraid I can't do that”. I'll get over it….

The God View



Somewhere on the (simulated) ILS RWY 16R into Van Nuys (KVNY) I can hear John clacking away on the keyboard behind me and to my right. Cool! I think — he's cooking something up to make my life harder. Sure enough, closer in on the approach, I start hearing thunder over the sound of the engine, and drops of water start hitting the screen. Not as visually disturbing (or just disturbing, in its own way…) as the prancing deer he had on the runway on the simulated FREES8 departure out of Santa Rosa (KSTS) a short time earlier, but in real life much more dangerous. But this isn't real life, and, sadly, the simulator doesn't rock or shake or buck wildly in the storm, and after telling John in real life I'd back right out of this approach now with ATC help, I fly on regardless, successfully breaking out a little above minimums and landing as well as one can in a sim like this (i.e. badly).

I've done this approach in real life (see e.g. "One Six Right"), and the real life version's much more scenic (especially at night), but I don't have the luxury of being able to do it in real life until I get IFR current again. Which is why I'm here at the sim, doing the remainder of the IPC with John. The time goes quickly, with a barrage of approaches, holds, departures, prancing deer, instrument failures, etc., and after what seems like a sweaty forever, I'm current again. It's been a long trek back, but worth it, I think, and I start thinking about a real-life trek to Van Nuys or Burbank later this year in one of the club's DA-40s, with the usual IFR leg into and back out of the LA basin. We shall see, as I keep saying.

Later, John sends me the picture above of the God View from the session, with the storms bearing down on the approach from the west. The joys of simulation….

Nothing Goes Horribly Wrong...

Somewhere 3,500' over the Diablo Valley, setting up for the RNAV 28L approach back into Hayward (KWHD) as I'm under the Cone of Stupidity in 7PV, Foreflight on my little old iPad mini just ... disappears. The screen goes blank; I'm locked out of the system. The proper response under these conditions should be a shrugged Simpsonian "meh", and a mental note to debug / fix the issue in a minute or two when I've got the time, not when I'm setting things up on the G1000 or trying to keep up with ATC on the radio (never mind actually just, you know, flying the plane). After all, I'm in a G1000-equipped DA-40 in VMC, John is sitting there in the right seat as instructor, and at this point in the (pre-) approach, the iPad's just not essential. But, of course, the engineer in me takes over and I try to fix and debug it all there and then, with the predictable result that I miss a call from ATC and (to mangle metaphors) generally lose the thread of what I'm doing in the big picture.

Oh well — another good lesson, one I thought I'd learned years ago, but that obviously needs to be hammered back into that poor little brain of mine again. But Foreflight and the iPad come back, and things go on as before — a weirdly-enjoyable couple of hours of little failures and well-received lessons (from John and / or what passes for Real Life under the hood).

* * *

The aim of today's flight is to continue my (possibly-Quixotic) attempts to get instrument current again. And overall, nothing goes horribly wrong — the basics, such as staying the right way up and within IPC tolerances for altitude and heading, etc., are generally OK, and it's really enjoyable decoupling the autopilot and just flying the plane by hand on the approach back into Hayward or on the departure out of Napa, but I spend much of the flight not feeling entirely on top of things. Again, not the serious things — I don’t think I have any real issues with either of the approaches we do (the KAPC VOR 6 with circle to land on 18R (probably my last ever VOR approach — we do it because we still can), and KHWD’s RNAV 28L) or the LIZRD 3 departure out of Napa; even the home-made 7 DME arc to the final approach course at Napa feels straightforward (I used to find these difficult to visualise in the old steam gauge era, but nowadays they’re just “obvious”). But my handling of the integrated GFC 700 autopilot was agricultural, to put it mildly, and my radio work was often really bad (missed calls, indecision, saying way too much on air, etc.). Plus my engine management skills always seem to go to pot under the hood. But the flight director was magic — I’ll be using that as much as possible in the future, regardless of whether or not the AP is properly coupled.

Overall, a good series of lessons, and I don't feel that it's too unlikely I could get current in the next few weeks; I'm off to Bogotá in July for several weeks of work, so I want to try to have it all sewn up by then. If not, it's not going to be the end of the world.

* * *

(And the cause of the iPad's blanking? I'd blame heat if it had been a warmer day and the sun had been intense, but it was a standard Bay Area coastal summer's day (sort of like a London summer's day but gloomier), and I don't think it was that. I know it's happened to other pilots here and there, but it's new to me. Again, though, it's hardly a catastrophe, and when I set up an approach correctly, it's not the sort of failure that should cause me much more than a jolt of irritation...).

Blimey, It's Circular!




A few hundred feet above Hayward (KHWD), immediately after departing VFR for Concord (KCCR) on an IFR (re)training flight, I look at the panel in front of me to check my altitude. We're in a Class D airspace (KHWD) under a Class C airspace (KOAK) which is itself under a Class B airspace (KSFO), and I need to keep below 1,500' for the next few miles to avoid blundering into the overlying airspaces. Par for the course, of course, if you fly out of Hayward, but when I look at the altimeter it looks so… weird. I point at it and blurt out something like "Blimey! It's circular!" to John who's in the right seat. John laughs.

This is your brain on steam, I guess. All those circular electro-mechanical steam gauges in front of me — I remember them! — and it's even got an ADF! Mesmerizing, in its own sort of way. Quite a shock to this jaded G1000-spoiled techie, but what did I expect?!  I'm in one of the club's C172's instead of the usual DA-40, and this is obviously going to be an exercise in old-school IFR flying. Flying the way it was when I got my instrument rating a decade ago. Some pilots get nostalgic for this sort of thing, but not me — I'm just a bit bemused and rather apprehensive. It's not just the old steam gauges — can I also cope with being under the hood again after all this time? Can I keep on top of the process and ahead of things on an approach?

* * *

This wasn't really supposed to be about steam gauges or Cessna 172's — it was just supposed to be a way back into IFR flying for me. Which is why I'm flying with John today — to start the long process of getting IFR current and proficient again after a two+ year break from instrument flying. But the DA-40 and John weren't available at the same time for a while, and I thought it might actually be fun to fly the old 172 — and remember or relearn how to program the KLN 94 GPS or use an old-style heading indicator (HI) or an ADF. So I arranged things for today, and — as usual — set myself some easy targets. If I can get through the flight without upsetting the plane or making too many egregious mistakes, I'll feel confident enough to start working on the formal instrument proficiency check (IPC) that I need to get IFR current again.

This is actually the first non-G1000 (i.e. non-glass) panel I've flown PIC in (I think) more than seven years. It's also the first time I've flown a C172 in more than two years, and the first attempt at IFR since around that time as well. At least I have Foreflight on my iPad with me as a safety blanket. And the panel's not quite as bare as the one I started with all those billions of years ago, even if it does still look a little, uh, Twentieth Century.

* * *

Right from the start, this flight's just one damn thing after another, in so many unexpected ways. I'm not talking about the actual flying (more of which later), but about the broken nav light I find on pre-flight (meaning we have to be back earlier than I'd like), or the paper oil funnel that I lose in the cowl necessitating some deft work by John to retrieve it, or the way my headset starts a high-pitched screeching oscillation as we taxi to the runway (meaning I have to dig out a rarely-used second pair from my flight bag), or the total pilot-side audio system failure at the start of the LDA RWY 19R approach into Concord (basically meaning John has to handle the radios from that point on as I get plugged into the rear passenger intercom without PTT), or the ADF that doesn't actually work properly, or the … well, I'll stop there, because I'm making it sound like some sort of trial or annoying chore. It wasn't — this was actually a really enjoyable flight, and although I'll probably never fly this particular aircraft IFR (except maybe to get through a thin benign summer stratus layer back into Hayward or something), it's definitely fun to sit in the left seat of a 172 again and play old-time Real IFR pilot.

Predictably, my instruments skills are rusty, my instrument flying rough. The first time around the practice LDA 19R into Concord (with full pilot nav) is an endless procession of missed cues and my looking blankly at the KLN 94 GPS wondering how the hell I should set it up for the procedure turn or the next leg, etc. And I'm not even under the Cone Of Stupidity for this first time around — and I'm using the autopilot, for at least some of the way (before I ditch it and hand-fly for the rest of the flight — much more satisfying).

And when I do go under the hood, while my actual flying isn't terrible, it's hardly going to impress anyone. What does make me feel good, though, is just how quickly I internalize what the tiny attitude indicator (AI) and other instruments are telling me when I'm under the hood — I think that was my biggest worry, steam gauges or not, but it turns out it's not much of a problem at all. I feel gratifyingly comfortable mentally integrating all the needles, planes, and numbers the entire flight in ways that are simultaneously quite different from my way of working with the G1000 in detail but fundamentally the same with the big (mental) picture. Probably the thing that most flummoxes me during the flight is the inscrutable interface on the KLN 94 (an interface I once actually knew really well); I basically have to get John to prompt me every time I reprogram it or set it up for another approach. I have a few blank moments with the simple OBS as well — mostly, though, to do with how it relates to the KLN 94 rather than what it's telling me or how it works in general. So I start feeling good about things, despite the roughness and puzzled moments.

I manage to blot my copybook, though, with one monumental blunder — on the start of the circle-to-32R maneuver at 700' I confuse Concord's runway 01L with the intended landing runway 32R, which is something I haven't done since my student days, I think. I'd probably have caught it fairly quickly and not caused some sort of international incident (I always check with the HI), but it was still a sobering thing to do. Thank god John caught the error early on and I could get away with a normal landing on the correct runway as though I knew what I was really doing. The landing (a touch and go) itself was also pretty rough — all that time away from the 172 is definitely showing.

The second time around the LDA 19R approach — this time entirely under the hood and hand-flown — is smoother and better-executed, but still not precise or particularly inspiring; John still has to quietly prompt me here and there. And I'm definitely helped by having John have to do the radios for me; I'd probably be flying a lot worse without that help. And I've intermittently got the old death grip again on the yoke, something I thought I'd been cured of years ago. But as I tell John, at least I haven't killed anyone (yet), and it's definitely turning into a really enjoyable flight.

We go missed again at Concord and head south for the ILS 28R into Oakland (KOAK), an approach I think I've said a million times that I could probably do in my sleep. But I'm actually wide awake right now, and I wonder how this one's going to turn out — it's one thing to be able to remember all the fixes and waypoints off the top of your head (and I can), it's another to be able to dredge up the muscle memories that let you make those small smooth adjustments on the way down the glideslope to keep you falling off the localiser. We shall see.

As we're heading towards the ILS with NorCal Approach, John makes gentle fun of my accent and then admits he can't do an Australian accent to save himself. I taunt him with the observation that my first instructor Dave Montoya (RIP) could do a wicked good imitation of my accent, especially on-air, and that in any case, I don't really have an Australian accent any more — it's actually always been some sort of weird Anglo-Australian, and really never was truly Australian (I have three nationalities, and was born in in a country that really doesn't exist any more). John tries a few phrases, but he'll need a lot of coaching before he'll pass as an Aussie; I suspect it's easier for me to get IFR current and proficient again than John learning my accent. I'll do the funny accents on this flight if he'll do the radios, I guess.

The ILS goes surprisingly well — John gets me to fly the AI so that the top of the AI plane's wings are just touching the bottom of the horizon bars, which works wonderfully — and I nail the approach, looking up at about 500' feeling pretty good at seeing the runway dead ahead. Woohoo!

We go missed (well, you don't really go missed at Oakland, you just terminate the approach) and depart for Hayward, where I (finally!) land smoothly and gracefully. Mission accomplished, I think.

* * *

So how serious am I about getting IFR-current and proficient again? Fairly serious, is probably the best answer — I definitely miss the challenges and fun of doing approaches, and the ability to get back in when the nearly omnipresent stratus layer comes in over Hayward or Oakland in the non-winter, but the cost of staying current can still be prohibitive. I'll probably book another instrument flight with John fairly soon, this time in the DA-40 (or some sort of G1000-equipped airplane), and if that also goes well, I'll try a full instrument proficiency check with him after that.

We shall see, as I always say.

Traffic's A Coyote At 8,000 Feet

I'm under the Cone of Stupidity in Cessna 051 somewhere a mile or two out from the runway threshold on the Stockton (KSCK) RNAV 29R approach when the tower controller tells us to exercise caution for (as I hear it) a coyote at 8,000'. Several things immediately go through my mind as we bump along the approach: a) Umm, what?! It's bad enough that the approach is seriously bumpy, but we have to contend with a coyote at 8,000'?! b) Is "Coyote" actually some sort of aircraft type, and he's calling traffic? c) We're below 1,000' — why would he call out anything at 8,000' unless it was dropping like a brick (or, for that matter, a coyote). It's a mystery to me, so I quickly ask Evan H., my safety pilot sitting in the right seat, what the hell the controller just said.

Evan patiently explains that it sounds like there's been a report of a coyote on the runway at around the 8,000' marker. Well, that makes much more sense, but I still ask the controller to say again. He does, a bit more clearly this time, and I reply with an enthusiastic "Yeah! we'll definitely keep a lookout for that!". In the end there's no sign of any coyotes anywhere on this or the next few landings, but it's hardly the first time I've either seen or been warned about a fox or coyote or dog on the runway here at Stockton or Livermore or even at my home base, Oakland (KOAK).

And it's already been that sort of flight, not the flight I expected, and a flight full of little errors or miscommunications, none of which amount to much, but all of which when put together make me feel glad I was under the hood in clear (bumpy) VMC rather than in actual IMC.


* * *

It started a few days ago, when Evan and I were supposed to do this flight on a weekday evening (rather than a Saturday morning), but the flight was scrubbed when I noticed that the port side (red) nav light was inoperative (no matter how much I banged on the wing); we rebooked for this morning.

Then came the forecast: I'd filed a real IFR flight plan to and from Stockton because the forecast the previous night had implied there'd be a deep coastal stratus layer over much of the Bay Area today, and the weather had been rather weird for the previous few days (it very nearly rained in Oakland last night, which in California terms is surely one of the four horsemen of some sort of apocalypse). But the day dawns bright and clear, if a little cold and blustery. So none of the benign actual IMC I'd really hoped for, unfortunately.

I check NOTAMS and such, and notice that Oakland's radar — a large part of the Bay Area's approach system — is NOTAMED OTS, and with it out, Oakland's Class C surface area and associated services are temporarily gone. No big deal — this has happened before when I've been flying and it's not going to make any difference to the flight.

Then doing the rental paperwork at Oakland Flyers, we hear that 051's G1000 has some sort of problem that supposedly makes the database out of date, and that cross-filling from the PFD to the MFD also isn't working. OK, I guess we can do this flight VFR with practice approaches then… (I prefer to do things on a real IFR flight plan just to keep current on things like copying clearances, etc.).

Out at the hangar I notice the lock's missing from the hangar door and point it out to Evan, thinking "that's careless…". Then I open the door and burst out with a surprised "Where's the bloody plane?!" The entire hangar is empty. OK, time to actually look at the book — sure enough, in tiny characters on the front where it used to say "Hangar XYZ" it now says "Hangar ABC" — RTFM, I guess, but no one at the club mentioned it'd been re-hangared a few hundred metres away — and it'd been in the original hangar only a couple of days ago when the original flight was scrubbed. No big deal, I guess.

We pre-flight 051, then get in and start up. Three things are immediately obvious: 1) the database is actually up to date — maybe we can do this on the IFR flight plan, after all; 2) Yes, there's some sort of weird PFD / MFD cross-fill problem, which is going to make things irritating but not too difficult with the two of us paying attention (I wouldn't want to do this in single pilot IMC); and, 3) The standby (mechanical) AI seems to have lost its tiny mind and is revolving and swirling like something from The Exorcist (a movie I've never actually seen, but never mind). The standby AI doesn't settle down after a couple of minutes, and since it's quite distracting, Evan covers it with one of his inop covers. We decide we'll depart VFR and just do the approaches as practice approaches — after all, this is just an IFR currency flight, and the weather is clear VMC as far as Stockton, at least.

By the time we've done the runup off 27R the standby AI's settled down, but we still depart VFR. We head for the Central Valley — and that lovely weather turns out to be bumpy. Not quite continuously, and not severely, but it's a factor in almost every approach and cruise segment for the next two hours, and it's the sort of bumpiness that anyone not a pilot would probably find tedious at best, sick-making at worst.

We get the practice approaches set up with a bit of extra programming (Evan just replicates on the MFD what I'm doing on the PFD), and after plodding on bumpily across the Central Valley we do the RNAV 29R into Stockton with full pilot nav, including the hold-in-lieu at OXJEF. The bumpiness is close to too much for the autopilot, but I sadistically keep it engaged for most of the way to see how well it could cope. Not very well, is the answer, and after the coyote thing and a smooth touch-and-go, we go missed back to NorCal approach. I re-engage the autopilot at about 2,000' in what I think is the correct altitude mode, but the bloody thing just keeps the plane climbing; at 2,200' I cut the autopilot out of the equation and start diving back to the assigned 2,000'. I can sort the issue out later… and, after setting up the next approach that's what I do.

This time around on the same approach it's just too bumpy for the autopilot, and I hand-fly the entire approach, a little roughly, but quite a lot better than the autopilot last time. However, this time my landing is really pretty bad — I blame the sudden windshear just as I'm flaring, but whatever it was, we bounced, and I had to use the throttle to ensure we didn't land hard on the second bounce. Not too bad, but a lesson in wariness. And, once again, on the missed I engage the autopilot in what I think is straight and level mode at 2,000' — and it starts climbing. This time I'm more on top of it and we don't bust altitude too badly, but I'm always a bit aghast at how much trouble I have with this unit in altitude mode (it's all me, the unit itself is just fine). Just to add to the overall feeling that not everything is going as well as I'd like, I keep making minor radio errors (missing calls, not understanding the controller, etc.) for the approaches (it seems to clear up as I get closer to Oakland for some reason).

We request, set up for, and get the ILS 29R with vectors, and things go better with the autopilot this time around, but I watch it like a hawk. And this time around my landing is OK, considering the windshear, but there are still no coyotes to be seen, which kinda disappoints me. We go missed as published and I let the autopilot drive us around the hold at ORANG, just because I really enjoy seeing this particular chore automated (and I am, after all, an engineer who delights in technology like this). After once around the hold we depart with VFR flight following back to Oakland.

This part — the VFR flight back to Oakland — is not without its hazards either. For much of the past 45 minutes we've been hearing parachute drop zone announcements (there were several drop zones NOTAMED for today in the area), and we have to be careful and listen to the controller to ensure we don't get caught in anything bad. There's a drop in progress over Lodi, but that's quite some distance north of us, and another supposedly closer in to Stockton, but nothing was ever announced on air as we flew by. And just as we're getting towards Byron (C83), Evan suddenly points out a flight of four or five military jets slightly below us, maybe two miles away, going rather quickly towards Sacramento. A nice sight (they're maneuvering in not-quite-aerobatic ways as they shoot past), but I kinda wish NorCal had pointed them out to us as traffic. Oh well. We watch them disappear rapidly northwards, hoping they don't reappear back in our direction.

All through the flight from just after takeoff one of the G1000's MFD fuel gauges intermittently shows a red 'X' for a few seconds and then reverts to normal; it seemed to stop doing this around Stockton, but it's back again. Oh well, another thing to squawk when we get on the ground.

We set up for and request the RNAV Y 27L back in to Oakland, and potter on towards JUPAP as requested. Nothing much to report about this segment except it's still bumpy, but (predictably) the air's clear and cool. We get vectored for the approach, and at first I let the autopilot handle things, which it seems to be doing OK. But just past the final approach fix, even though it's captured the (LPV) glideslope, it just can't seem to cope with the near continual windshear, and we end up two dots above the glideslope. Time to take over, I think, and I disengage the autopilot and hand fly the rest of the approach successfully and fairly smoothly down to about 400'. It's a weird sort of day when my hand flying is smoother and more accurate than the autopilot, but there you are. But however smooth the approach, I land badly on 27L. Once again, due, I think, to low-level windshear in the flare, I billow down the runway and have to salvage things with some throttle work. Nothing terrible, but a bit of a blow to the ego, I guess.

Back in Oakland Flyers I do the paperwork and notice that the tach time we took from the MFD is way out. I suspect that maybe the G1000 cross-fill problem has affected the tach time (or not — I just don't know) on the MFD without affecting the rest of the engine instruments. Whatever the cause, it means I have to trudge back out through the security gate to the hangar and back again just to see what the tach time is on the PFD; it's much more believable this time (and yes, I check what the MFD displays — we didn't misread it, it was maybe ten hours out). Back in the clubhouse again, my pen stops working as I'm trying to finish the paperwork. It's been that sort of day, really….

Hand Made

Just as I'm turning to a new heading for the vector NorCal Approach has given us for the Livermore KLVK ILS 25R approach, the 172's autopilot gives up the ghost with a distinct lack of drama. Just a little blink, the usual autopilot disconnect sound, and then a blank panel display. Dammit, I think, this flight is supposed to be at least as much about keeping on top of the G1000 and autopilot combination while under the hood as anything else, and now half of it's lost its tiny mind and isn't quite all there…. John's sitting in the right seat as safety pilot and without missing a beat says "just hand fly it". Well, he would say that, wouldn't he? Well, I would have said the same thing if I wasn't under the Cone Of Stupidity and thinking at the speed of molasses, and if my engineer brain wouldn't keep trying to debug things like this on the fly, but I know the deal, and we plod off towards the approach under my control in the cool clear darkness of the Bay Area night.

Predictably, closer in to the runway my flying gets agricultural (as we would say where I come from), and while I don't break PTS standards, neither do I set any records for accuracy and stability. I over-control the whole way down, and decide to look up 100' above the decision altitude before I make total hash of the approach. I salvage things a little bit (and over the next few landings) by absolutely nailing the landing, but still, I feel mortified — I usually do better than that on hand-flown approaches, and it's not like it's a difficult approach or the weather's getting in the way or anything. The only other saving grace is that — so far, at least — my radio work's not terrible: it's usually the first thing that goes to pieces after a long break from flying.

We do a bunch of stop-and-goes in the darkness at Livermore, then depart VFR back to Oakland (KOAK), but we already know we'll need a real IFR clearance to get home due to the coastal stratus layer that's moved in over the inner Bay area, and we gird ourselves for a stretch of ad hoc holding or circling out here in the clear skies above the Diablo Valley before we're allowed home. It doesn't sound promising when I call NorCal and ask for a clearance back from over Dublin (the one in Northern California, not the one I used to visit occasionally for my job when I lived in London…) — the controller effectively asks if we're OK with at least a ten minute delay in getting the clearance. I reply with a resigned "affirmative", but almost as soon as I've loaded the G1000 for the RNAV Y 27L approach back to Oakland, we're given a heading that looks suspiciously like a vector towards the approach just outside JUPAP, the initial fix. Sure enough, a few nautical miles closer in we're cleared for the approach, with a request for best forward speed (we're already doing that, but it's the thought that counts, I guess). I hand fly down towards the stratus layer, and in a few minutes, after a small amount of actual IMC and yet another smooth landing, we're on the ground. It's deserted down here, and we taxi off towards Landmark, unable to raise them on Unicom for fuel. At least I flew this approach with some sort of accuracy and stability, and it's all starting to come back to me. And as we wander in to Landmark to find out why they're not talking to us (we never find out in this case, but the Landmark staff are as pleasant and friendly to us as they always are), I feel pleased that I'm current again: IFR-current, night / day landing-current, and club-current. Every little bit helps….

This was supposed to be a simple short club- and landings-currency VFR flight caused by my having started a new job and losing the flying thread for way too many weeks, but the coastal stratus closed in on us earlier than predicted, and by the time we were at the airport preflighting the plane, it was obvious we'd need to depart and return IFR, even though (as usual) it was clear less than ten nautical miles to the east and / or 2,000' above us all the way east to (I'd guess) Nevada. I wasn't too upset — if I could get two approaches in I'd extend my IFR currency enough to be useful, and if John was up for a longer flight (we weren't going to depart much before 9PM), I was keen. And so it went — the only other interesting thing about the flight being that it was the first time I was using my new iPad with Foreflight for serious in-plane navigation. It's not like I haven't used John's iPad before (YAFB passim), and I'm an early Foreflight booster, so it's all fairly familiar, but actually doing it on-the-fly (as it were) while under the hood and on a real clearance is novel, and I occasionally have to ask John for advice on the best way to do things. On the other hand, I can't imagine flying IFR or even VFR in the future without the iPad (or something similar); I think the only really irritating thing was being unable to get the clearance down on the iPad — I had to scrawl it down with my left hand on my real (paper) pad. Yes, I'm vaguely ambidextrous, but still, I'll have to get a better way of copying the clearance on my iPad only. The other thing I need to get set up is the Foreflight checklist app, but that was just me being too busy over the last few weeks to get that together. Maybe next week (there's always next week).

The other thing that got our attention was a small underwing-engined RJ of some sort in Finnair livery parked at Landmark. As we taxi past we wonder what it is; I can't help noting mordantly that it looks a bit like the pictures I've seen of the Sukhoi that crashed in Indonesia last week, but Finnair (to my knowledge, at least) doesn't have Sukhois, and neither of us is sure what it really is. Later, I look it up on Wikipedia — it's an Embraer E-190, but what it's doing here in Oakland I don't know. I'm surely one of the tiny handful of Oaklanders who's not only actually flown Finnair, but who's been to Finland, so it doesn't seem likely they're scouting out a new Oakland direct Helsinki flight or have suddenly decided that Oakland's their new US hub, and it's unlikely to be a sports team charter (which usually accounts for some of the larger jets parked in front of Landmark). Just one of those Oakland mysteries, I guess.

What Could Possiblie Go Wrong? (Rust Never Sleeps, Part 2)

Things are going quite well for me under the cone of stupidity on Yet Another Quest For Currency (the aviation sort, not the hard stuff I can use to get boutique bagels and exotic coffees down at the neighbourhood local). John's in the right seat, watching carefully. We've left Stockton (KSCK) behind after having successfully completed several approaches and landings in the still darkness of a Central Valley autumn night.

John's given me his iPad to play with on the next approach, the ILS into Livermore (KLVK), and it's working nicely with my new Dual XGPS150 GPS unit sitting up there on the dash. I've also got my little iPhone in my hand as I watch how well it works without coupling to the Dual (it'll only couple to one Bluetooth device at a time). Well, it does quite well, actually, and I feel pretty impressed with all the technology surrounding me (but it's really me doing all the real work, telling the G1000 what to do and such — well, that's what I like to tell myself). Suddenly I can't help it: "Siri! Set up a practice ILS 25R approach into Livermore from our current position, please!" Siri does nothing — either she's not listening, or she's as confused by my accent as everyone else is, and I revert to doing it all myself again. Oh well; I'm guessing we'll have to wait a few years before that'll work (and if you don't know who Siri is, this blog's probably not for you :-)).

Anyway, that's not the "what" that could possiblie go wrong in the title (diehard Simpsons fans will probably get the reference). What went wrong was the string of mostly weather-related cancellations and postponements that lead up to this flight — all sparked off (I'm absolutely certain) by my ending an earlier email to John with the words "what could possibly go wrong?". I'm just not the sharpest tool in the tool shed: one day I'll learn not to tempt fate like that. So what did go wrong? An example: we had to cancel our previous attempt when a howling gale caused by an unusually-strong high pressure system sitting somewhere over Utah was driving high-speed rivers of wind down over the Sierras and the coastal ranges towards the Pacific. As locals will know, this makes for unpleasant turbulence pretty much anywhere within sight of a mountain range or even hills (and there are ranges everywhere in California…). I looked up the winds on DUATS: 65 knots at 6,000 — a nice tailwind if you can get it, but we'd be going straight into it for at least half the flight, and that's a fierce source of rotors and bumps even over the Valley or in the lee of the Berkeley Hills (especially in the lee of the Berkeley Hills).

I might have been up for it even given all that, but my knee's still a bit iffy and I thought the better of it. So here we are, several non-existent flights later (I'll spare you the details of the other delays and cancellations).

The ILS into Livermore goes reasonably well — I'm getting better with practice — and we do the low approach past the tower over 25R when I come out from under the hood. Woohoo! (I always feel like doing a victory roll on low approaches — a hangover from my aerobatics days — but I know better, honestly). And now it's off to Oakland for the ILS 27R approach back home….

This goes fairly well as well, but we get the slam onto the localiser from somewhere between GROVE and UPACI intersections, and I can barely bring myself to program in the required 1,100 fpm descent to capture the glideslope from below. We just don't get low enough, and in the end I take over and hand fly the last few minutes (which kinda negated the point of this approach — it was supposed to be about managing the G1000. Oh well). The landing on 27R goes well (they've all gone well tonight, which was pleasing after all the time off from flying) and we taxi back to the Port-A-Ports.

* * *

Yes, I'm current again — but still a bit rusty. There's a touch of the old death grip creeping back to haunt my control of the plane, and my radio work definitely needs some polishing, but overall, this flight went basically as planned, despite all the preceding hiccups. We started it by taking off from Oakland's runway 9L, a bit of a treat for me: the winds nearly always favour one of the 27's, and I hadn't taken off from 9L for literally years, and we ended it an hour or two later with me feeling fairly OK about my flying, especially the landings and the big-picture procedural issues on the approaches. My hand flying on one of the approaches was definitely a little agricultural, but hey, I can't do everything.

* * *

Earlier, while prepping the flight I do due diligence with DUATS and notice the following NOTAM:

!FDC 1/1954 SCK FI/T IAP STOCKTON METROPOLITAN, STOCKTON, CA.
ILS OR LOC RWY 29R, AMDT 19...
S-LOC 29R MINIMUMS NA.
CIRCLING MINIMUMS NA.
JOTLY LOM HOLDING NA.
TERMINAL ROUTES ORANG TO JOTLY LOM, LIN VORTAC TO JOTLY LOM,
WRAPS TO JOTLY LOM, ECA VOR/DME TO JOTLY LOM NA.
MSA WITHIN 25 NM OF ECA VOR/DME, 070-160 3000, 160-250 5300,
250-340 3400, 340-070 4200.
JOTLY LOM DECOMMISSIONED.

Hmmm, I think — what the hell does that mean? It basically seems to mean there's simply no way to do my fave ILS for currency at the moment. But why make the approach unavailable that way? Why not just NOTAM the entire approach N/A? I ask John — he's not entirely sure what the FAA's thinking with this either, so I decree that we'll just do the RNAV 29R approach out there instead. It's all flying to me….

Rust Never Sleeps

On the LOC RWY 36L missed approach out of Napa (KAPC) I go back under the Cone Of Stupidity, tell tower we've gone missed, then get back to Oakland Center to tell them what we're planning, all while twiddling the relevant knobs on the G1000 to get me to the hold as published at Scaggs Island VOR (SGD) and setting up the autopilot for the climb and hold. I start feeling a bit better about what has so far been a rusty flight, with shaky radio work and somewhat iffy flying. Worse than either of those, though, was that I'd been distracted at a crucial time while prepping the approach and forgot to set the altimeter according to Napa's ATIS, leaving it on Oakland's setting, a really basic error, but one that in this case wouldn't mean much in reality — especially given how close Napa and Oakland are. But still — these things can have serious consequences in less benign circumstances….

We do a leisurely turn around the hold, I tell Oakland we're departing back towards Oakland VFR from the hold, then punch in KOAK direct. No problems — everything feels smooth and under control, and the plane's going well, it's a nice night out there, and I'm starting to get back into the groove, thinking ahead about setting up a practice approach back into Oakland. I don't actually have any preferences for this, so John suggests the RNAV Y 27L, an approach I've done only marginally fewer times than I've done the ILS back into Oakland (or so it feels — sometimes I pine for the old NDB RWY 27R approach with its hair-raising tendency to throw you at the wrong side of the airport up close and personal to a 777 landing on runway 29, or something smaller coming straight at you in the pattern for 27L. A bit of variety goes a long way, you know).

Anyway, we get handed off to NorCal approach and I ask for the practice approach. The controller acknowledges this, gives me a vector, clears me into the class bravo, and tells me to expect the approach down the line. So far so good. I anticipate we'll very soon be sent direct JUPAP (a useful intermediate fix (IF) on the approach), and reach over to set up the approach on the G1000. And, surprise surprise, the usual keystrokes aren't producing the usual response — and I have absolutely no idea what it's telling me. I sit there for a few seconds. John suggests I try it on his side (on the MFD); the same thing happens. I sit there for a few more seconds, quite unsure what to do. The menu options are simply not what I expect for the sequence of button pushes I've just done. What the hell is happening?

I don't panic, but it takes a few seconds — and some prompting from John — to get myself out of the mess (which is a classic G1000 Thing I won't go into here, but that I should have recognised easily). In the meantime, of course, I've lost the plot a bit, and it takes time to return to normal and set the approach up. A few seconds later we're heading direct for JUPAP, and all's (relatively) well again, but I'm back feeling rusty — very rusty.

But fairly quickly I realise that the real rustiness here is in the way I handled the unexpected, not in flying or planning or understanding the procedures themselves — after all, apart from the faux pas with the Napa altitude setting, I didn't really do anything wrong, I just did things sloppily (especially with the radio, when I reverted to long-winded plain English requests for what should have been terse by-the-book transmissions). My rustiness is mostly in forgetting to concentrate on getting around the problem (by any means necessary…) rather than on working out why something happened, at least in the short term. Don't get sidetracked! I take the little lesson to heart, and we plod on, waiting for further vectors or "direct JUPAP" (which never comes, but never mind — it's vectors all the way, as usual).

There's enough actual IMC on the way back in to Oakland that we end up needing a real clearance, and I take the hood off as we skim over and then through the light stratus layer — this part's as enjoyable as ever. I hand fly the approach (with LPV guidance) back in to Oakland feeling much better, and nail it to ATP standards (on a night like tonight, that's not hard, but still…). On the ground the ramp seems quite dead, and we taxi back to the Port-A-Ports and wait for the fuel truck. Outside the plane it's actually quite cold for this time of year in Northern California, quite a lot colder than I'd expected, and I rue the fact that my winter jacket is sitting in the back of my car somewhere on the other side of the security fence. Oh well, I'll survive.

* * *

This should have been an extensive IFR workout with John to regain both currency and competency (I wanted to do at least four approaches and a couple of holds as well as en-route stuff this evening), but I've injured my right knee sometime in the past month. I don't remember any specific incident, but whatever it was I made it much worse last Friday night when I spent six hours continuously standing, walking, running, climbing, crouching, etc., without a break with a heavy ENG video camera attached to my shoulder at the annual Beats 4 Boobs breast cancer fund raiser (I do the videography for the event — check out Beats 4 Boobs SF 2010 for a taste of my work…). By the start of the flight this evening, it's obvious I'm going to have trouble doing more than a relatively gentle workout, and I warn John we might have to cut it short (and that I might have to have him take the controls while I push my seat back to stretch my leg). And so it goes — by the time we do the stop and go at Napa, my leg's quite painful, and after the hold at Scaggs Island, it's clear that I'm not even going to be able to do the series of night stop and goes I'd wanted to do to regain night currency back in Oakland. It's disappointing, but I'm not dumb enough to push it too hard (except when it involves a San Francisco fashion event…); maybe next time. By the time I'm back home, I'm in quite a lot of pain, and starting to think maybe I should see a doctor. We shall see… (I come from a medical family, most of whose members would probably rather eat broken glass than see a doctor).

May Showers

Puddles at the Port-A-Port hangars, Oakland North Field, KOAK, California



I live in a part of the world — Northern California — where you can confidently make plans for late May and know it won't rain. There might be a bit of coastal stratus or fog, and it might be a lot cooler (or hotter) than you'd hoped for, but it won't rain. It just doesn't rain around here — at all — from late April to early November in a typical year (and when it does, it's literally front page news, with breathless live reports on the evening TV news shows). So a few weeks ago when I booked a flight for this evening, I didn't give it much thought: a nice VFR run down to Monterey (KMRY) or up to Santa Rosa (KSTS), with a passenger or two who'd enjoy the view.

But when I check the forecast a day or two ahead, it's for rain. I've lived here long enough to not really take that forecast seriously — the weather guys get it wrong, a lot, when they forecast rain at this time of the year. But we've had a record year for rain (and snow up in the Sierras), and earlier today it's obvious: this isn't going to be a VFR sight-seeing flight, if it happens at all. I tell my passengers that the flight's off, but I keep the reservation, thinking I might get some nice IFR in (actual) IMC experience if things turn out OK — it's relatively warm, the airmass is fairly stable and predictable (at least on the large scale), and if I don't stray too far from home, I might safely spend a significant proportion of the flight peering out into that bright white or grey enveloping the windshield. Not the sort of thing a typical passenger would probably enjoy, but definitely my kind of fun.

And so it goes: by the time I'm at Oakland (KOAK) in the early evening, it's raining, and the field's IFR — the ceiling's low (but not too low to get back in safely if something goes wrong on departure), and the visibility's down to maybe 1.5 miles (officially; unofficially I'd have said it wasn't more than a mile in some directions). I've filed a couple of suitable IFR flight plans, and I've checked and checked (and rechecked) DUATS and Foreflight, so I'm cautiously optimistic that I'll be able to fly. The weather at my chosen destination (Napa, KAPC) is better than at Oakland (but still pretty mixed), and the en route freezing levels are fairly high (a few thousand feet higher than the highest altitude I'm likely to get assigned going there or getting back). Nexrad shows nothing serious, and there are no reported thunderstorms or anything especially worrisome in the area. And it's a short flight, combining a fair IFR procedural and communications workout with several outs in case of problems. So what am I waiting for?!

Not much, really, and after a careful pre-flight, I'm sitting at the run up area off 27R with rain streaming down around me, programming my clearance to Napa (basically vectors for SABLO intersection, Scaggs Island VOR (SGD), direct, a route I've been given many times, IMC or not). From experience I predict it'll actually be flown with a couple of initial vectors, then REBAS intersection direct, then straight onto the localiser for runway 36L. Which is basically exactly what happens — after being cleared for departure I enter the clouds at maybe 1,000', and spend the next fifteen or so minutes in and out of (mostly in) IMC as a rather benign set of stratus and cumulus passes around me at 4,000'. I monitor the outside air temperature (OAT) every few minutes; it doesn't go below about 4C the entire time; each time I break out I look around for thunderheads or anything malicious, but really, it's all looking rather nice; it's not even turbulent except for some very minor stuff here and there. There's not much traffic on-frequency, and I don't (quite) get the usual Napa slam on to the localiser — this time I'm basically left to my own devices from fairly early on and can get down early rather than attempting a 1500 fpm descent in actual.

On the localiser into Napa I break out very early, then realise that, while Napa airport itself is actually VFR, I'm about to follow the localiser back into some extensive cloud — the localiser seems to be boring its way through the only large cloud formation in the area. If I were VFR at the moment, I'd just go a mile or two left or right (it wouldn't matter much which), and I'd be safely and legally VFR all the way to the runway. But I head on regardless, straight down the localiser, straight back into the clouds, and break out again well inside LYLLY (the IAF) at maybe 1,000' — and a mile or two to either side the ceiling's at least 5,000'. Yes, the clouds seem to have deliberately formed a long tunnel around the localiser, which makes me smile as I break out. Following Napa tower's instructions, I circle south for runway 24, and land on a wet runway in what seems to be a very dead time for KAPC; the place sounds and feels deserted (all those Northern Californians afraid of the unseasonal rain, I suspect). I taxi back to runway 24's runup area and wait for my next clearance, which comes after a minute or two's delay. The clearance is exactly what I expect, and after another minute or two of programming and double-checking, I'm cleared for departure.

A minute or so later, I'm back in IMC, heading for Scaggs Island VOR (SGD), then REBAS intersection. Just past SGD I'm given "Oakland direct, expect the ILS 27R", and that's what happens, with the inevitable stream of vectors for the ILS and traffic closer in to Oakland. The cloud bottoms and tops are all over the place now, and I'm in IMC pretty much continuously until I break out on the ILS back into Oakland. Every now and then I break out between clouds or layers; at one point I see the Southwest 737 I've been hearing on the radio paralleling me 1,000' higher and off to my 2 o'clock as we both break into one of those cloud canyons; then it's gone again (I can see it on the G1000's traffic display, as well; remarkably, it doesn't seem to be going much quicker than me, which can't be true). A few minutes later ATC calls traffic at my one o'clock, heading north, type and altitude unknown; I respond that I'm in IMC but I'll keep a look out if I get clear of the clouds. A few seconds later I break out into another cloud canyon, and there a few thousand feet below me, very (very) close to the ground flying up a valley in the hills, scud running below a broken layer, is a yellow Husky or Cub (or similar — it's a bit difficult to tell from this distance). He disappears below the layer as I tell the controller what I'm seeing and tell him if that's the traffic, I have it in sight — or not, as by then I'm already back in IMC.

I get vectored onto the ILS back into Oakland, and break out at about 900'. Landing's pretty routine, and I taxi to Kaiser for fuel. It starts raining again just as I start refueling (of course!); but it's definitely clearing on the larger scale, if a little raggedly. Just as I finish refueling, I slip badly and manage to scratch the paint on the leading edge of the wing — a small scratch, maybe 3cm long, and not really visible unless you're looking for it, at least in the semi-light during refueling and hangaring — but things like this always end up costing an arm and a leg, and later I squawk the scratch with a small mea culpa. We shall see what this ends up costing me….

Back in the hangar, the evening sun breaks out weakly as I'm closing up, and the Port-A-Ports where I am become a lovely mess of puddles, sunshine, structure, and the odd sodden business jet. Hence the photos above and below, taken from the hangar. Not quite what this Anglo-Australian Californian expected to see at this time of year, but never mind.

A good flight — quite a lot of benign actual IMC, and, as always with a short IFR flight to Napa, quite a navigational and procedural workout. It's a shame about the paint scratch (and the pulled shoulder from the same slip), but it's all flying — in some way or another….

Tree Of Life

We're pottering along in Cessna 051, 2,000' above the darkness of a quiet Central Valley night, on a wide downwind vector for the ILS back into Stockton (KSCK). A few minutes earlier we'd gone missed as planned on the KSCK RNAV 29R approach after a nice stop-and-go, the first of a projected four or five approaches to get me IFR current (and proficient) again. We're discussing John's new bluetooth GPS for his iPad (which he's brought along and is showing me how it works in real-world use), waiting for another vector back towards the localiser. We're also (of course) idly listening with one ear to NorCal Approach's frequency, when — out of nowhere — a voice we connect with a certain semi-local bizjet we'd heard earlier on-frequency pipes up and asks in a rather faux innocent tone something like "so when did you guys [ATC] start saying 'tree' and 'fife' for 'three' and 'five'? It sounds really funny to me" (yes, our controller's been saying 'tree' and 'fife' quite by the book all the while).

Argh, I think. Not this again — they've been saying it that way for years now, especially the newer controllers (and it's even in the AIM) — where's this guy been all that time? Or is he just trying to be funny? The controller responds with a fairly non-committal answer along the lines of "that's the way we're supposed to say it now", and the other guy persists with several lines about how silly it sounds; and, several times, we can hear the controller's increasingly "I-don't-really-want-to-be-having-this-conversation" responses coming back between the calls to other planes for real stuff.

Just as I'm snidely remarking to John that hell, that's the way we in large parts of UnAmerica have been saying it for a while now, and what's with all the Good Ole Boys in America coming out of the woodwork and complaining about it, a new voice pipes up on frequency — a (much) older no-nonsense voice (I'd almost swear it's Lou except the voice isn't quite his) that simply points out that 'tree' has been the way it's been for a long time, and what's to complain about? (and, implicitly, "get with the program!"). So much for stereotypes. I'm tempted to add my own accented voice to the conversation (something along the lines of "bloody whingeing yanks!" :-)), but, as I've complained about in the past, my accent really marks me out on air, and I'd never get away with it ("Cessna 051! That was you, wasn't it?! Expect to hold at JOTLY for 35 minutes!"). And, in any case, as John reminds me, "American" is actually now one of my (several) nationalities, so who am I to complain?! Humph. The controller tries to end it all by handing the original complainer off to the next sector, but the pilot on the other end can't help getting in a parting shot that (I guess) was intended to be humorous, but just comes off as lamely missing the point (again). We plod on in the darkness over the Central Valley, marveling at the state of radiophonic discourse and aviation standards-keeping, waiting for that vector….

A few seconds later it comes, and we head off towards the localiser, my brain back in approach mode. I hand fly the ILS (under the hood) steadily down to 150' with John watching like a hawk in the right seat — not bad for a flight that started out with me feeling very rusty indeed. It surely helps that the wind's fairly constant (a quartering tailwind right down to the ground) and the traffic's nonexistent.

We go missed again, and back with NorCal we ask for and get full pilot nav for the Tracy (KTCY) RNAV 26 approach, starting at our current position with OMWAP as the IAF, and including the course reversal hold. This goes well (with the G1000 steering us around the hold), and John gets to do the landing after I look up at the MDA. About the only interesting thing about this approach is the use of waypoint names like "OMWAP" or "IVABE"; John and I argue about how the latter should be pronounced, and the controller avoids using it at all. Back with NorCal on the missed we head back to Oakland for the ILS 27R.

Somewhere close to GROVE for the localiser we start hearing a non-stop string of approach clearances, vectors for traffic, and ATC instructions on air, and just as I'm remarking to John about how it's suddenly a zoo out there, we get a square 360 for traffic on the ILS — traffic we can see on the G1000's TIS as several white diamonds converging on the localiser in an interesting-looking cluster. Par for the course for Oakland, I guess, but I enjoy this sort of thing, and I'm usually happy to go a long way out of my way for faster traffic and to make the controller's life easier (it's all flying, dammit, and it's always good IFR flying exercise). By the time we're back on vectors for the localiser and cleared for the ILS, there's only one plane competing with us for the approach, an Amflight Navajo bearing down on us from a dozen miles behind us Out There somewhere beyond our TIS display.

The ILS is an approach I know like the back of my hand — an approach I nearly botch in the last few moments as I'm hand-flying under the cone of stupidity and John casually suggests setting the flaps in a specific way that combines a momentary throttling back with flap deployment (nothing tricky, just done in a way I don't normally do). I make the mistake of thinking about it and then doing it, which puts me dot or two to the left and a dot low on the ILS before I recover — I should have just ignored John or done it by instinct, I guess. Still, no one dies as a result of my over-thinking, and the landing is a success.

We taxi to the Business Jet Center for fuel, and discover it's a bit of a zoo as well — a CHP helicopter, a King Air, and an anonymous and expensive Gulfstream, or Challenger or whatever are all departing from in front of Business Jets simultaneously, and we make damn sure Cessna 051's out of the way and has its control locks in. I stand outside on the ramp for a minute in the thick of things watching the CHP helicopter depart sideways to avoid hitting 051 and the business jet, and the noise of all three aircraft in the night is astonishing — the sort of thing you usually either love or hate (you can probably guess which applies to me).

After hangaring 051 John signs my logbook, and I'm IFR current again. What matters at least as much, of course, is whether I'm proficient as well, but after a bunch of hand-flown approaches and similar exercises, I don't feel too bad.

September 25, 2010

Hot And High

It's another hot Central Valley day out there; this time, though, I'm in the right seat as safety pilot for Evan. He's under the hood as we approach Linden VOR (LIN) for the VOR/DME RWY 1 approach into Westover Field / Amador County Airport (KJAQ, a.k.a. "Jackson"). I briefly look over the approach plate and make fun of Evan for picking what looks like the easiest approach in the state. About the only thing that's even mildly interesting about it is the note that says use Sacramento Executive's altimeter setting if you can't get the local one — but KSAC's something like 35 miles away and in a different sort of physical environment altogether. I guess the 300' MDA penalty takes care of that, but in any case we've got the local AWOS on COM 2 and it's not just giving us the altimeter settings and all the usual boring stuff about wind and ceilings, etc., it's giving us the local FBO's Avgas and Jet-A prices! And damn they're cheap, at least compared to home (Oakland, KOAK) or a lot of other places in the area. Pity we don't need fuel.

We get to Linden VOR and turn to the final approach course. It's hot dry country down there, shimmering golden-brown Sierra foothills studded with green oaks and the occasional man-made lake or reservoir under the relentless California sun. Classic gold rush country. We've been cleared for the practice approach some time ago, and we're turned over to CTAF quite early. It's the usual Central Valley mass of incoherent, inconsistent, or hapless calls and stepped-on transmissions from the usual distant suspects like Gnoss (KDVO) and Tracy (KTCY) and much (much) further away, but there's no sign of anyone on air at Jackson itself. We potter on along the approach course at a steady 3,000' MSL, past the LIN 8 DME fix and towards the LIN 15 DME fix. We both think it's kinda quaint (or at least unusual) to be doing a VOR approach, let alone one without a GPS overlay (I was kinda surprised to see it existed at all when Evan mentioned that'd be the approach we'd do). There's no doubt that this is a straightforward approach, even if it's a VOR approach — in fact it's one of those approaches without even a published procedure turn, and whose missed approach notes just basically tell you to turn around and backtrack twenty-something nautical miles to Linden VOR, at which point … well, what? That's where the missed instructions end.

I can see the runway from about five miles out, and we debate whether to do a circling approach to runway 19 or a straight in to runway 1. The AWOS claims a very mild wind favouring runway 1, but we actually have a slight tailwind at 3,000'. We decide on the straight in, especially since the runway's long enough that even if the density altitude is fairly high and there's a 2 knot tailwind, we'll be fine. Evan makes a few calls on CTAF, but all we hear is the staticky squeally babble from far away, and we potter on. Past the LIN 15 DME fix the runway and airport environment get clearer — the runway basically sags in the middle and it seems to be sitting on a small semi-wooded hill. Nothing terribly unusual for the California foothills, but you never know — a deer might dart out from nowhere or the hot wind might suddenly start gusting something terrible at ground level.

As we get closer I notice that Evan is still going along at 3,000'; my instincts tell me we need to start lower now, and I hint at the issue over the intercom. Nothing worrying, at least not yet, but that airport environment down there looks a little unforgiving if — like me, and like Evan — you've never even seen the place before, let along landed there. Evan's OK with the current altitude, and we potter on; the weather's hot as hell even up here, but there's really no wind at all. Still no one else on CTAF or (as far as I can see) in the pattern. A minute later we're still too high in my judgment, and this time I let Evan know a bit more forcefully. Still nothing too worrisome, but Evan mutters something and points the nose down while cutting back on the power.

We start descending, but maybe not enough — within another mile or so I tell Evan we're still high; he says he's working on it. We're bang on laterally — it's just the altitude that's off. We both notice simultaneously that the tailwind has strengthened quite a lot in the last few miles, and Evan again considers circling. I obsess more and more about the altitude, and say so out loud again. We approach at quite a high rate of speed, the runway looking more and more scary as we get closer. Evan starts counting the altitude down in hundreds; I start thinking we're going to have to go missed, but I stay quiet this time. At the MDA, Evan looks up — and swears. Yes, we're way high, very fast across the ground, and it's even hotter down here than either of us had expected. And the runway's almost beneath us. It takes Evan about a second to decide to go around and go missed, and we do what amounts to a low approach over the runway at full power, climbing in the heat, and announcing our broad intentions on CTAF. Good move, I say to Evan. He gets the plane re-trimmed and pointing in the right direction, then says he just hadn't realized how fast we'd been going across the ground (ATIS was no help here), and how much quicker he'd needed to descend. Hot and high, and no way he was going to land on a small unfamiliar hilly runway with a tailwind in this heat.

We go back to NorCal for our next destination. Not for the first time, I guess, I jinxed an approach by making fun of it; but this was definitely one of the few times I've been involved in a real unplanned missed approach. Quite a lesson.

The rest of the flight's another lesson — mostly in how to cope with the heat and glare of the Central Valley and at Mather (KMHR) after a perfect approach and landing there by Evan, and in trying to decipher ATC's true intentions on the way back into Oakland. At one stage on vectors for the practice ILS approach into Oakland in the left seat I get a string of conflicting and inconsistent altitude assignments (in quick succession, something like "maintain 4,000", "descend maintain 3,000", "at or above 3,000", "at or below 3,500", etc. — all altitudes quite unusual in my experience for where we are at the time), and, inevitably, a few minutes later by "83Y, what's your assigned altitude?". I have the immediate IFR pilot's reaction to this — horror that I've busted an altitude somewhere — but for once it's not a controller hint, it's a case of (I suspect) a controller getting his wires crossed and thinking we're someone else (also, we're actually VFR in Class E airspace at that point, but still…).

Back on the ground at Oakland, the Texas Rangers 757 is parked near Kaiser next to the old Alaska hangar; I guess it's here for the North American Men's Baseball Championships (a.k.a. "The World Series"). It's looking sleek and expensive there in the sun. Later, 83Y's hangar is shady but still hot, and we struggle to clean all the million or so squashed bugs off the leading edges (an inevitable part of flying above the Central Valley) and generally tidy things up. Evan's still wondering about the missed approach (a go-around, really), but there's not a lot to wonder about: he got it right in the bigger picture, and if the tailwind was a lot stronger than forecast or as observed on the ground, well, there are an awful lot worse things to do than going around when you look up at the MDA and don't see the runway where you think you should….
