TRUE

Robert,

I am under the impression what I did was a commercial maneuver. This
is done for emergency descents for commercial jet jockeys and of
course Lears wouldn't be doing acro flight..

See http://discussions.flightaware.com/v...?p=87546#87546
where I raised this question before undertaking the exercise.
Thoughts?

First of all, I really doubt that anyone other than the NetKops on UseNet
care whether you were conducting acrobatic flight. Personally, the only
reason I can think of for an emergency descent in a non-pressurized light
single is a fire; and in that case I might not stop at 90 degrees. Besides,
in an actual emergency, "ya gotta do what ya gotta do" and being prepared
under non-emergency conditions is usually more than half the battle!

As to commercial jets, each type may require a type rating and each type
rating may include a recommended procedure. There is an article on flying
corporate and commercial turbine powered aircraft in each issue of AOPA
Pilot, and one of the issues about a year ago did include a simulated
emergency descent. In the aircraft type involved, it was easily possible
for an attendant or passenger to be standing in the cabin at the time that
an emergency might develope; so IIRC the proceedure used in the article was
to roll about 30 degrees and push over sufficiently to feel a little light
in the seat (about 1/2G) while retarding the thrust levers to flight idle.
The article covered the procedure trained by a particular operator of a
particular aircraft type.
