“Unable”: Your Ace in the Hole
If you’re anything like me, your e-mail account is perpetually filling up with newsletters, magazines, digests, announcements and offers from the likes of AOPA, EAA, IAC, NBAA, AVweb, AIN, and others. I wouldn’t call this stuff junk mail or spam, because it’s useful, aviation-related information that I solicited at some point.
But to be honest, there are times that the endless stream of data pouring into my computer feels like a gentle, Matrix-esque form of digital waterboarding. Add in a healthy stream of blogs, podcasts, RSS feeds etc. and it can be a full-time job keeping up with it all. In response, I’ve become rather adept at quickly skimming these publications and adding a few select articles to my reading list before hitting the delete key.
Still, there’s a lot of good stuff out there. One of my favorites is the “IFR Fix” column on the AOPA web site. Author Dan Namowitz keeps the writing short and sweet, yet always imparts a thought-provoking lesson. Even if you’re not instrument-rated, there’s much to be gleaned from his posts.
For example, Dan recently penned an article about an aircraft which was only a few hundred feet above minimums on an instrument approach and got a rude shock from the controller.
The twin was 300 feet above minimums, descending, when ATC called with new missed approach instructions.
“Advise ready to copy.”
The pilot flying was undergoing a checkride for an air-taxi operator. The check pilot responded to the radio call.
“I said that it was a really bad time, but go ahead,” recounted the check pilot in a complaint to the Aviation Safety Reporting System, noting great displeasure at having to copy alternate missed approach instructions at such a high-workload stage.
Since this was a checkride, the aircraft was probably on a practice approach in good VFR weather while the pilot flying was wearing a view-limiting device. The controller was likely aware of the weather, but since most of them these days are not pilots, probably didn’t understand why it would be a problem to make a pilot write a long series of instructions down on paper just as he was approaching the ground.
Three hundred feet is about 30 seconds of flying time. It’s unreasonable to expect a pilot to grab a pen and paper, transcribe the procedure, read it back, set up the radios correctly, and still fly the plane. Even if the aircraft’s flying on autopilot, the request was outlandish at best.
Lest you think that this is something which would only occur in VMC, let me say I’ve had this happen in actual low IMC while flying into Chino (KCNO). And would you believe it didn’t phase me in the least? No stress, no sweat, no frantic scribbling with one hand while trying to control the airplane with the other. You might be thinking I’m some sort of aviation Superman… and in a way you’d be right. I have a super power at my disposal that can crush the most dastardly schemes of evil air traffic controllers in a single second.
I’ll let you in on another secret: you have this power too. It’s called “unable”. That word is your salvation and one which probably doesn’t get used often enough, because as pilots we don’t like to admit that we’re incapable. Incapable is a word we associate with failure and a lack of personal ability. We’re genetically programmed to do everything in our power to comply with a controller’s instructions. Besides, if ATC asks you to do something, there’s an implied assertion that you should be able to do it. Otherwise why would they be asking? Aren’t they trained professionals who know what they’re doing?
Maybe. But don’t be fooled by that authoritative sounding voice-from-on-high, controllers are not infallible. They’re not pilots. And they most certainly are not in command if your airplane. You are.
It’s an important distinction, and I take it as a huge accomplishment when a student of mine learns to use this magic word. The list of crazy things I’ve seen them instructed to do by FAA certified air traffic controllers is long, and it’s not limited to IFR operations, either.
How many of these do you recognize?
- Increase taxi speed
- Taxi routing too close to jet blast
- Last minute circling instructions
- Slam dunk approaches
- Maintain high speed until short final
- Early crosswind turns at low altitude
- Cancel takeoff clearance after V1 (yes, that happened to me!)
- “Exit at taxiway X” while too fast
- Last minute alternate missed approach instruction
- Clear to takeoff or land into a wake turbulence hazard
- Vectored onto an approach inside the FAF
- Vectored onto an approach way too high
- Controller cancels IFR without pilot assent
- Instructed NOT to go-around (we did anyway)
- Vectored underneath a low-flying helicopter in the pattern
You don’t have to do any of these. According to the FAA’s Pilot-Controller Glossary, the word unable “indicates inability to comply with a specific instruction, request, or clearance.” Very simple.
The reason doesn’t really matter. It could be safety-related, or infer a lack of equipment (GPS, for instance) or pilot certification (instrument rating or currency) for the requested action. It might be high pilot workload, low time-in-type, unfamiliarity with the phraseology or maneuver, or literally any other reason. If you’re not comfortable, then don’t do it. That little voice in the back of your head and those hairs on the back of your neck are worth listening to.
I’ve refused quite a few instructions over the years, but looking back, if I could do it all over again I’d refuse a few more. There’s a VFR departure procedure leaving Santa Barbara which takes single engine aircraft way out over the water at very low altitude. I’ve flown that one on a dozen occasions and I kick myself for accepting it every. single. time.
I understand the reason for the limitation (traffic separation), but that’s simply not my problem. It’d be better to hold on the ground until the departure path is clear for a climb than to get sent out over miles of cold ocean at low altitude in a single-engine aircraft, especially if you’re not equipped with rafts and life vests and/or have passengers who cannot swim.
If you’re in a twin, that’s a different story. But the procedure at SBA doesn’t make any distinction, so it falls to the pilot, and far too often I’ve failed to make the smart choice. If more aviators were to do so, the flurry of refusals would probably cause the procedure to be changed, resulting in a safety improvement for the rest of our brethren.
Getting back to Namowitz’s example, the check pilot did accept the alternate missed approach instruction, but were I in his shoes I’d have refused it for two reasons. Not only was it a poor idea to be head-down while low and descending, but there’s also the issue of setting up the missed approach procedure. These days, many of us are equipped with TSO-C129/145 GPS receivers and typically fly all missed approaches with GPS guidance.
Naturally, we should be prepared in case reversion to a ground-based navaid is required, but even if you were prepared for that eventuality, according to the Aeronautical Information Manual, many alternate missed procedures are not published, even if the holding fix is. That means the procedure will not appear in the database or on the approach plate. The only way to obtain it is by having ATC verbally communicate it to you over the radio. Right out of 1940, folks.
“Some locations may have a preplanned alternate missed approach procedure for use in the event the primary navaid used for the missed approach procedure is unavailable,” explains the Aeronautical Information Manual.”To avoid confusion, the alternate missed approach instructions are not published on the chart. However, the alternate missed approach holding pattern will be depicted on the instrument approach chart for pilot situational awareness and to assist ATC by not having to issue detailed holding instructions.” The alternate missed approach also may use navaids not part of the approach or the primary missed approach.
How ironic is that? The alternate missed is used for instances where a navaid (typically ground based) is unavailable, but with GPS we can go there anyway. It’d be infinitely safer to simply allow a /G, /F, or other suitably equipped airplane to fly the published missed even if the navaid was offline.
So was the controller the bad guy here? Not necessarily. They simply follow approved procedures for moving traffic. If the airplane has multiple pilots on board and they’re familiar with the area, this could’ve almost been a reasonable request. Almost. But for a single pilot in actual IMC? No way. The best response is to focus on the instruments, fly the plane, put down the pencil, and give the controller the only read back he needs to hear:
It’s a beautiful thing.
