Roseland:
...I doubt when you're sinking at 10,000fps (close on 100kts) any amount of power will unstall you without putting the nose down.
At altitude, doubly so, because of less dense air, in turn directly related to LESS ENGINE THRUST AVAILABLE, as well as slower engine windup rate.
Reducing AOA does the job right now.
BTW, Roseland, do you mean 10,000 fpm, not fps?
