stall with max power I saw a video of a test flight of a GA plane and it stalled with max power and with a moderate AOA (angle of attack). How can a plane stall with max power (with the wings flying below the critical angle of attack)?
A plane (airfoil) can stall at any airspeed and/or power setting so long as the critical angle of attack is exceeded. Airplanes stalling only below a specified airspeed is a common misconception largely due to the fact planes are usually listed with a “stall speed” below which the aircraft will generally stall in most situations. However if the critical angle of attack is exceeded at a higher speed a stall can also occur. The only way to know the critical angle of attack is from an angle of attack measurement device installed on the airframe it is inherently somewhat different than the aircrafts attitude.
