Cruise stall recovery
In our company we developed the following cruise stall recovery by trial and error in the B747-400 simulator due to the fact that the aircraft would not accelerate in level flight with full power...
Select VS -3000 ft/min
(stick shaker stops almost at once)
When IAS is half way up amber caution range...
Reduce VS in 100 ft/min stages with caution...
When IAS is at top of amber caution range...
Select FLCH to recover in protected mode to cruise alt.
Typical height loss is 2000-2500 feet.
Training Captains with plenty of time in the simulator could with trial and error finesse this to a height loss of 1000 feet but often nibbled the stick shaker...the above method works every time for regular line pilots.
