stall with max power
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.
