Stall recovery technique
Dear Pumpkinpilot:
My point is that JAR states "with minimum height loss".
This implies using power in the stall recovery which is not from an aerodynamic perspective the right thing to do when you have gone beyond the critical angle of attack for the wing.
How does a glider recover from a stall?
NASA tested a B757 at 41,000 feet and applied full power in the stall - the RoD was 2000 fpm!
Colgan Q400: 2300ft, gear down, flaps 10 deg, stick shaker activated and AP was disengaged. Power was increased to 75% TQ. Crew pulled 25lb on yoke, aircraft pitched UP 31 deg. Followed by 45 deg nose down and 45 deg bank to left before 105 deg right. RoD 9600 fpm last 800 feet to impact.
Adding power at stall warning with prop a/c leads to prop disc loading that is assymetric which leads to nose pitch UP and yawing moment - hence spin entry.
The Priority is to unstall wing then add power (20% above stall speed for JAR25 test flying).
