Can an airplane stall at any altitude?
Absolutely! Since stalls are an AOA (angle of attack) issue, the type of airplane doesn't matter. As Chief Pilot Daun said, “an airplane can stall at any altitude, airspeed or attitude.” So the question that comes to mind is, “how are stalls in airliners different from stalls in small airplanes?”
