DEEP STALLS some thoughts
DY
Several mentions have been made a 'deep stall' - why? This is a specific stall condition mostly defined as "A condition such that the turbulent wake of a stalled main wing "blankets" the horizontal stabilizer, rendering the elevators ineffective and preventing the aircraft from recovering from the stall." Neither the BEA note, or any of the more 'thoughtful' contributors believe this aircraft was in any kind of "deep stall" I think it fair to say.
At the top of the zoom climb with the airspeed dropping to below 60 kts the flight controls are literally useless. What the plane will do then is literally unknown. But this one did not respond to any inputs. It did not change until the end. Thus it was out of control at that point. Like many many other craft in the same situation.
And therefore in a "DEEP STALL"!
PS: I'm thoughtful.
