I am very interested to know more about deep stall recovery of a conventional jet (such as the B737) with a swept back wing, wing mounted engines and conventional tail.
My guess would have been to initially apply up to full forward control column in an effort to reduce the AoA of the wings and holding that full forward position (or at least reducing only to the point of pulling zero G's) until such time that the airspeed is sufficient for the wings to pull the positive G's required to recover from the dive without stalling a second time.
No doubt there would be high rates of descent involved. At low levels, this would be a major problem. I wonder how low is too low.
I'm guessing there is initially a chance that the tailplane might stall. After-all it is at a high angle of attack too and you have, by pushing the control collumn forward, put it's co-efficient of lift at a maximum.
Approach-to-stall recovery calls for the application of maximum thrust. I'm not sure if that the pitch-up moment is desireable during a deep stall.
Is it possible do describe a generic deep stall recovery technique for the type of jet aircraft described above and perhaps outline the different considerations between approach-to-stall and deep stall?
Thankyou.
