accelerated stall

A stall entered during accelerated flight (i.e., during maneuvers). During such maneuvers, when the stalling angle is reached, the aircraft stalls at higher speeds than it would during a normal stall in straight and level flight; the speed is directly proportional to the square root of the applied load factor. For example, an aircraft whose stalling speed during level flight is 150 knots will stall at 300 knots when it is pulled out of a dive with 4 g force. Also known as high-speed stall.

Failure to take immediate steps toward recovery when an accelerated stall occurs may result in a complete loss of flight control, notably, power-on spins.
The Corsair was much less a handful than the P-51 when flown into an accelerated stall, although it was by no means as forgiving as the F6F Hellcat.
Accelerated stall from maneuvering aggressively in the traffic pattern, for example, constant altitude skidding turn from base to final at a steep bank angle with increased AoA (increased wing loading).
As the turn tightens, more pitch/power is necessary to maintain altitude, until we start pulling some G and enter an accelerated stall.
A common misconception among primary students is that an accelerated stall involves increasing airspeed.
Any reduction in stall speed also theoretically requires a commensurate reduction in maneuvering speed, the speed at which an accelerated stall unloads the wing before structural damage occurs.
Because CF is increased with a skidding turn--when compared to a properly coordinated turn--wing loading increases and contributes to increases in stalling speed, which predisposes to an accelerated stall.
With the slip-skid ball far to the right, an accelerated stall occurred while yawing left.
A traditional accelerated stall demonstration is begun from a level flight attitude at reduced power and at or below [V.
