Oh well I will tell all 3 examiners that they are wrong!
Good! Please do.
Firstly how much is some? and how much reduction in AOA
There is NO mandated maximum acceptable height loss. As regards quantifying the specific reduction in AoA, that is something I told them had been omitted from their procedure. Current teaching for light aircraft stall recovery
pitch attitude states (or should state) 'contol column centrally forward until the warning/ident ceases, then maintain that attitude'. That would seem equally applicable to large aircraft stalls - it's what I used to use when taking the VC10K to the stall warning during full flight tests. If applied promptly and correctly, the attitude change can be very small indeed and the loss of height will also be very slight.
It's important also to note that you could be very close to the stall when the stick shaker operates (assuming the aircraft is so fitted) if the wing has collected leading edge icing - which might not be obvious at night or in cloud. Which is why the recommendation is to recover using the same technique whether you receive a stall warning or a stall ident.
