I never said that you will get "green line "vacuum. I did say that
the gyro's will continue to work with the vacuum that you will have
with a windmilling engine. Go to 10K, windmill, and see that you still
have useable gyro's. Been there, done that, they still work.

How long did you windmill? After all, the gyros are going to
continue to spin for some time with no vacuum. The slower they go,
the more difficulty they're going to have.

Did you go for more than 5 or 10 minutes and verify that they were
still working acceptably?


My gyros spin up from stopped to a usable state while my engines idle after startup.
Don't yours?
