ACCELERATED STALL - Any stall made to occur at other than 1g.
ACCESSORY GROUP - Mechanical and electrical units mounted on an engine necessary for its operation, such as starter, magnetos, fuel pumps, etc.
Accelerated Stalls can occur at higher-than-normal airspeeds due to abrupt and/or excessive control applications. These stalls may occur in steep turns, pull-ups, or other abrupt changes in flight path.

11: Nonturning Accelerated Stall
In an aerobatic loop, you are pulling about 4 Gs at the bottom, so the stalling speed is about twice what it would be in ordinary unaccelerated flight.
These symptoms describe the low speed non accelerated stall. Its possible to induce stall at higher speeds as in level turns and fast pitch up accelerations where some symptoms will not show at all.
Angle of Attack compared to Relative Wind ...
This is the reason for the phenomenal turning ability (imposition of g-load on the wings in a turn before an accelerated stall occurs) of the airplane, allowing it to turn more sharply than any Allied fighter of the time.
An increase in altitude will further increase the angle of attack in a 2-g turn. This is why pilots practice "accelerated stalls" which illustrate that an airplane can stall at any speed. For any speed there is a load that will induce a stall.
