Off to find a wide-awake cat and a ****ed-off duck.

Do we have to undershoot or overshoot the cat on north or south
headings?

Don't shoot the cat, or someone will call the SPCA

Can you inagine? You might as well read tea leaves to decide where up
is.

Groan!

Once again you're totally clueless. Your Directional Gyro is vacuum
driven. If you only needed electric instruments to fly, your primary
instruments wouldn't be pitot-static. If you have an electrical
problem, bus failure or inflight fire, you might lose all your
electrical instruments.

You think it terms of tiny airplanes.


Bertie doesn't, and he agrees with me: You're clueless.

Sure it is.
As long as you're not accelerating, which is something
that can be sensed by audio RPM , the magnetic
compass can operate as an artificial horizon too,
because it's like a plumb-bob.
It's of course, independant of operating systems.

You haven't flown, really, have you? If you had, you'd
know that the compass, being suspended from a pivot, is kept upright
by gravity, just like the ball in the turn coordinator stays in the
bottom of its tube by gravity. However, in a coordinated turn, the
TC's ball stays centered and the compass's card stays level with the
airplane's wings, not with the horizon. If it did we wouldn't need to
spend $900 on an attitude indicator; we could use the ball and
compass.
The compass reads all haywire during turns, too, not just
during acceleration. You can't use it to roll out on a heading. Timed
turns are for that.
Both you and Mx would be awful surprised the first time you
flew under the hood or in IMC. Vertigo, or what we call "crookedhead"
around here, would get you big time in no time. It surprises all new
guys, especially guys who "have it all figured out" and are trying to
teach the teachers. They come home with their tails between their
legs, same as the know-it-all trike pilot who has just had his first
taildragger experience.

Meanwhile, you don't cite your sources, so I suspect that you are a liar.

If I cared nothing about others, I'd suggest that you go up and do some flying
in IMC to make me a liar.

I do fly in IMC, liar.

A climb. You cannot tell whether you are climbing or turning based on
sensations alone in IMC.

You wouldn't know. You haven't done it.

I have. And...let me check...I'm still alive.

:O

Go play with your toy airplanes.

No doubt. But I'm not debating this with the FAA.

I quoted you chapter and verse directly from the FAA, and you
contradicted it, liar.

Bye now. Your opinions here are not worth further reading or discussion.

Well duh, it's a magnetic compass in a fluid.
The fluid can leak out.

What? Your TV screen is that realistic?

Shouldn't set Kool-Aid glasses on the monitor.

It doesn't even stay level with the airplane! Compass dip will have it
doing all sorts of tricks. Trying to keep up with one of them in a turn
is very difficult to say the least. Even turning to a north or south
heading using lead lag should almost be classed as wishful thinking.
