Where this duff gen originated from heaven knows but one thing is for sure, and that it's has been regurgitated for the past 40 years and passed down from instructor to instructor.

It may go back to the time the Wirraway was the RAAF advanced single engine trainer. The stall in a Wirraway was characterised by a sharp wing drop. Instinctive use of aileron to prevent further wing drop invariably caused the wing to drop further because of the increased angle attack of the aileron on the dropped wing. While that was true of some wartime designs, post war trainers like the Cessna and Piper range were subject to civil certification and wing design meant stalls were benign

Wartime accent was placed on not using aileron initially and this was reflected in flying training manuals of that era. Rather than use aileron. use of rudder was taught based on the premise that skidding the aircraft to wings level was better than risking further wing drop if aileron was used.

As we now know, this technique was not optimum for wing drop recovery but it's interpretation persisted through the years possibly because the majority of flying instructors employed by aero clubs were former military personnel. Thus the myth was perpetuated to this day despite the correct method of recovery from a dropped wing at point of stall published in the CASA flight instructors manual.
