These exercises were done in the sim at 10,000' in order to take a little of the stress out & ensure that impact did not occur, as that was considered negative training. Perhaps they should have been done at lower altitudes in order to create a realistic scenario & instil some respect for the seriousness of the situation.
Negative training - rubbish. The best low level stall recovery training is on short final at 800 feet on a coupled approach then close both thrust levers to simulate autothrottle system failure. That is basically what happened in the Turkish Airlines crash at Amsterdam. The airspeed rapidly bleeds off and the stab trim works overtime trimming back to hold the coupled glide slope. The stick shaker sounds about VREF minus 30 knots. It is best demonstrated first by a competent instructor, because things happen so quickly.
On go-around from VREF minus 30, thrust increase gives a strong pitch up already exacerbated by almost full back stab trim at the time the stick shaker operates. This is not a play fun exercise but deadly serious and it takes several attempts before recovery technique is refined. This is exactly what simulators are for.
But to conduct landing configuration stall recoveries at 5-10,000 ft in a simulator in order to avoid someone's idea of "negative training" is ridiculous.
