The current method of unusual attitude "training" at the PPL and CPL phase is a couple of steepish turns and slightly nose high/low pitch angles meanwhile the student is supposed to close his eyes so he cannot see what the instructor is doing. Then the student is permitted to open his eyes and look at the instruments (usually after a quick peek outside from under the hood) and recover to level flight.
There is already 10 hour IF requirement for CPL, but I do agree it would be useful, maybe just some IF unusual attitude recovery would be of great value, without going the whole nine (expensive) yards
What a waste of time and money. First of all, if a non-instrument rated pilot encounters IMC or at night gets into a UA inadvertently, he certainly won't have his eyes closed looking down at his knees. He will see what is going on and unless he has been properly trained in UA interpretation and recovery on the clocks he could be in strife. A half hearted UA manoeuvre in a C150 taught by a grade 3 instructor in CAVOK is a total waste of time if only for the limitations imposed by a non-aerobatic aircraft.
Obviously there are limits to throwing around a light twin during instrument flying training in the real thing. Hoods or foggles or screens have their limitations and most of the time are not true IMC simulation because you can always see the sky at some point. The answer is to use a synthetic trainer where instrument indications of an unusual attitude can be studied at leisure and appropriate recovery action demonstrated. Of course control forces are not replicated but the main thing is instant recognition of the position the aircraft is in and the best recovery action. Think inverted in a flash behind an A380...
