But now you might point out that flying too slow in turbulence will increase the risk of an accelerated stall
. True, but a gust-induced stall usually is very brief and the wing recovers almost before the pilot realizes that it has happened.
The same is true of preventing an accelerated stall
in a base-to-final turn.
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.
An instructor introducing steep turns, for example, might say, "Now what do you think would happen if I kept pulling back while banked this far?" Voila: the accelerated stall
. And a trim stall demonstration helps prove the importance of timely configuration changes during go-arounds.
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 landing-configuration stalling speed (Vso) also increases, predisposing an accelerated stall
: Vso at 1 G = 48 KIAS, while Vso at 1.55 G = 60 KIAS.
As the turn tightens, more pitch/power is necessary to maintain altitude, until we start pulling some G and enter an accelerated stall
. All of which could be avoided if we imposed three basic limits on our low-level maneuvering.
A common misconception among primary students is that an accelerated stall
involves increasing airspeed.
In this V-N Diagram example, 20 mph (17 knots) below published VA results in about the same protection against damage from positive and negative gusts (Reference 5), with the accelerated stall
occurring at a lower total G.
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.
