Assuming the simulator instructor is suitably experienced to brief on how to recover from Unusual Attitudes - after all the Boeing 737 (for example) FCTM explains the procedure step-by-step - then it is a simple 15 minute procedure in the simulator to teach the subject. While most jet transport simulators may not have the ideal fidelity,the important thing is teaching the pilot instrument interpretation of the UA and its recovery. This is because most accidents involving UA fatalities started off by the crew having poor basic instrument flying skills in the first instance. Automation dependency does that for you.
If each recurrent simulator session was conducted with equal time spent on automatic flight and manual raw data flight, the problem would soon be solved. Crew blind concentration on - and hence almost total dependence on - the flight director, is the prime reason why basic instrument flying skills are being shot to pieces.
In turn, this becomes a vicious circle where low hour pilots such as MPL and their ilk who are the captains of the future, and for no fault of their own, have never known anything than glass cockpits, will always have trouble learning to fly by hand on instruments.
Even basic raw data flying such as touch and go circuits and landings is excellent scanning practice because things happen fast. The object being to increase scanning skills. That means switching off the automatic features such as autothrottle and FD. Yet rarely do instructors permit these manoeuvres during initial type rating and recurrent training on type. The solution above to preventing loss of control accidents caused directly by poor instrument flying skills, is so simple and cost effective. Instructors must not get bogged down wasting valuable simulator time with lengthy checklist reading when surely the priority is to give hands on flying.
Assuming that operators will never seriously encourage pilots to hand fly on revenue flights, even on the clearest of days or nights, then we should use the flight simulator to do the job. Anything is better than the current head-in-the sand approach to accidents based upon it always happens to the other fellow in some other country.
