Sorry BOAC,
While I can happily agree that a reduction in AoA is required I cannot accept that releasing backpressure is the correct response to a stall warning, it may be effective but it may not. Stall recovery procedures do not say "release any backpressure then if ineffective move the control column centrally forward". There is a reason for that. There are too many variables, rate of speed reduction, trim, power setting, nose attitude, bank angle, g load, control authority etc.
In the right circumstances releasing backpressure may be sufficient to remove a warning but what we have to have is a procedure that works and for people to understand that there is no ambiguity in how it is applied, that is why Boeing and Airbus rewrote their procedures in the light of recent tragic events.
If we're talking max rate turns or air combat in the buffet then things are different but that's a specialised environment.
