I used to give a standard extra time exercise on endorsement training (732/733/734) to emphasis the Flight with Unreliable Airspeed thing and for progressive I/F confidence building during the endorsement program. Worked a treat for the latter .. but, of course, relied on good pre-sim briefing and a nil-anxiety environment for the guys and gals up front.
(a) total speed and height info failure .. often the sim couldn't accomodate everything and we had to revert to covering those things which couldn't be failed by pressing buttons at the organ grinder's station
(b) T/O in restricted vis
(c) aim to fail everything desired by shortly after gear up - end up with no airspeed, altitude, VSI, radalt, etc., cues so that the crew had to rely on configuration, attitude, and thrust to continue the recovery
(d) crew flies a climbing circuit to intercept the ILS for recovery to nominal cat 1 minima
(e) check for compatible FPA/GS from the configuration, attitude and thrust numbers, considering expected wind
(f) fly it down to a landing
Most folk walked it in on the first attempt and I can't recall anyone needing more than a second look at the problem.
Not directly transferable to line operations in any sense and quite artificial ... but served a useful directed skills purpose. The guys and gals probably would never get to see a similar exercise again but the basics stay with them.
