A different aircraft, but perhaps with some similar characteristics :
In the January 2011 issue of Safety First, Jacques Roysay discusses Stall Warning and Stall. He says:
"A practical exercise done in flight in DIRECT LAW on an A340-600 and well reproduced on the simulator consists in performing a low level flight deceleration at idle until the SW is triggered, and then to push the THR to TOGA while continuing to pull on the stick to maintain the altitude.
The results of such a manoeuvre are:
In clean configuration, even if the pilot reacts immediately to the SW by commanding TOGA, when the thrust actually reaches TOGA ( 20 seconds later), the aircraft stalls.
In approach configuration, if the pilot reacts immediately to the SW, the aircraft reaches AoA stall - 2 degrees.
In approach configuration, if the pilot reacts with a delay of 2 seconds to the SW the aircraft stalls."
The example that I had done to me on a Britannia with a new Captain who HAD to go from Flight Idle to Overshoot, MAY have been faster... But it seemed an age. (A Merlin would have been even better.)
I would like to count the seconds OUT LOUD to remind myself just how long it really takes. ( On a sim, of course !)
( The usual Approach Power on a Britannia would have been about " 300 Torque". After THAT example, I never used less than " 250 Torque ".)
