Autopilot questions for small GA aircraft

On the 182 (with G1000 KAP 140) we can doing full coupled approaches.
The autopilot takes over when the wheels leave the ground and I don't
kick it off until 200 feet. Full GPSS, etc.

Doesn't that take some of the alleged fun out of flying a small airplane?


Just trolling now.

What about using the autopilot to trim, and then turning it off? I do this in
simulation, but only because the sim doesn't allow extremely precise trim
adjustments (as far as I know).

Recent aircraft (like the Cirrus) have a switch that automatically trims
off all the control force that you or your autopilot are holding. But the
sort of aircraft I can afford don't have that - you have to be pretty
close to trimmed before you can use the altitude hold.

But only an idiot would try an autopilot for the first time in IMC.

I dunno. A pilot who isn't IR might try to turn on the autopilot upon finding
himself in IMC in order to keep the aircraft straight and narrow while he
gathers his wits about him, even though he might not have ever had occasion to
use it previously. It would be a reasonably logical thing to try.

Sure, but it would be more logical to try out the autopilot when you're
checking out in the aircraft in the first place.

Both. Last week when I was doing my IPC I started to get airsick. I
immediately turned on the autopilot so I could take a break.

What is IPC?

Instrument Proficiency Check.

C has features?? I thought the whole point of that language was to
offer nothing but bare metal.

Sounds like aircraft will eventually go the way of cars, with only a few
idiot-light indicators and perhaps an airspeed indicator.

I can see trimming off force for the pilot, but I'm puzzled by the autopilot
interaction. Don't most autopilots work by adjusting trim to begin with (at
least for altitude)?

But the
sort of aircraft I can afford don't have that - you have to be pretty
close to trimmed before you can use the altitude hold.

What happens if you are far away when you engage the autopilot?

Sure, but it would be more logical to try out the autopilot when you're
checking out in the aircraft in the first place.

True, but when you're stuck in fog and you don't know anything about flying on
instruments, it might be instinctive to reach for something that could fly the
plane for you and give you some time to think of a way out of your situation.

Were you engaged in unusual maneuvers that made you sick? I don't know what
an IPC involves. One of my concerns about ever flying in a small airplane is
that the movements might make me sick, although I've never been airsick in
large aircraft (apart from some queasiness on one or two flights when I was
already sick with something else and we were flying through turbulence).

It disengages. If you're close but not right on, it flashes a "trim up"
or "trim down" light at you.

Part of checking out in a new aircraft is becoming familiar with *all*
aircraft systems - and you should do that in perfect weather. If you
haven't become familiar with all aircraft systems then you shouldn't be
flying it alone in marginal weather.

Yes. One of the required skills for instrument flight is recovery from
unusual attitudes. You close your eyes, your instructor tries to get you
disoriented, puts the plane in an unusual attitude - usually either a
steep spiral dive or a steep climb near stall. It's the "get you
disoriented" part that got me sick - my instructor likes to give you a
real roller coaster. The first recovery, I counted four really hard
positive G pulls, a couple of hard negative G pushes,some hard slips and
skids, and the stall horn went off a couple of times. The second recovery
was about the same.

Wait and see. Cirrus is doing very well.

And I'm sure every pilot follows that policy religiously. That's why
accidents never occur.

Has "zip" to do with the man's point.

Yes, by far most do. But you couldn't realize this having never flown.

Standard procedure with a good CFI.

Clueless as usual.

Paul,

Sounds like you know very little about what it means to pilot an aircraft.


Please! Not again! How can you possibly feed the idiot?

You do thast because you're a fjukkwit.

then maybe you'll be able to fly!
nah.
