Re unusual attitudes (aerobatics). Unusual attitude recovery training in Level D flight simulators is rarely practiced in simulator cyclic training for airline pilots. Occasionally it may take place on endorsement training. If so, it may be only once every three years and lasts five minutes at the most.
The usual excuse for not practicing unusual attitude training in jet transport/turbo-prop simulators (other than within the benign officially defined figures of 45 degrees angle of bank, pitch attitude 10 degrees nose down, 25 degrees nose up and within above parameters but flying at airspeeds inappropriate for the conditions), is simulator fidelity restrictions.
Keeping in mind that nearly all jet transport/turbo-prop accidents involving unusual attitudes have been in IMC or night where the crew proved incompetent at recovery on instruments.
There is good value however, in aerobatic training in a suitable light aircraft which after all is nothing more than recovery from unusual attitudes. The RAAF taught this in their elementary, basic and advanced flying schools in years past.
A one hour exposure to aerobatic training goes a long way to gaining confidence in unusual attitude recovery techniques and applies just as much to a jet/turbo-prop type as a Citabria.
That said, you don't have to go to the unnecessary expense of five hours dual in a Citabria. You are not qualifying for a tail wheel endorsement or an aerobatic endorsement. You merely want basic dual instruction aerobatic flying to include barrel rolls ie recovery from fully inverted - stall turns ie recovery from very nose high attitude and maybe a roll off the top (recovery from inverted slow flight).
So, if your airline simulator instructor doesn't have the time of five minutes (expense) or the inclination, to demonstrate to you the correct way of recovering from an unusual attitude (possibly because he is not confident of success himself
), then hire an aerobatic qualified instructor to teach you the basics in a suitable trainer. That is much better than just reading the theory in manuals.
Better still, try to practice the aeros under the hood and really improve your instrument scan. It will be money worth spent. But don't get talked into a tail-wheel endorsement or an aerobatic endorsement; unless of course you have the spare cash.
