Very wise.

4. Even if I tested it and it worked, I wouldn't rely on it working when
I need it.

Short answer: it was a guess.

Fair enough. My gyros behave fine on an instrument approach down to 1500
rpm, so I'd be pretty comfortable trusting them as long as I could keep my
Warrior's speed up high enough to spin the prop that fast; unfortunately,
with an engine out, that might mean descending a lot faster than I really
need to. As long as my TC were usable, I would find it hard to justify
sacrificing a lot of glide range just to keep the vacuum pump working.


All the best,


David
