Definition
Stalls that occur at airspeeds higher than the normal 1G stall speed because the wing is being loaded beyond 1G — typically during steep turns, abrupt pull-ups, or other maneuvers that increase the load factor on the aircraft. The wing still stalls at the same critical angle of attack; the higher airspeed is simply the speed required to reach that angle when the airplane is being accelerated.
Plain English
A stall that happens at a faster-than-usual speed because the pilot is pulling harder on the airplane — for example, in a tight turn or sudden pull-up. The wing reaches its stalling angle sooner because more is being asked of it.
Context Anchor
Seen in flight training syllabi, stall awareness lessons, steep turns, pull-ups, and discussions of avoiding stalls during maneuvering flight.
Derivation
‘Accelerated’ here doesn’t mean ‘going faster’ in the everyday sense. It refers to acceleration in the physics sense — any change in velocity, including a change in direction. Pulling into a steep turn accelerates the airplane (toward the center of the turn), which increases the load on the wing.
Why Pilots Care
It can produce an unexpected stall during turns or pull-ups at speeds well above the published stall speed, catching pilots who only watch airspeed.
Grounding Statement
Picture an airplane in a steep turn: even if the airspeed looks comfortable, the wing may be working hard enough to stall sooner than expected.
Intuition Check
Do not assume “accelerated” means the airplane must be speeding up. Here it means the wing is under extra load from maneuvering, so it can stall at a higher airspeed.
Example Sentence 1
During steep turn training, the instructor demonstrated an accelerated stall to show how the airplane can stall well above its published stall speed.
Example Sentence 2
Recognizing the onset of an accelerated stall in a chandelle allows the pilot to reduce back pressure before full stall develops.
