Dora-9,
You're quite correct, of course,my misuse of terminology.
The most important item in spin recovery in a Chipmunk was #1 on the pre-aerobatic checklist --- brakes off.
In the late '90s, I was quite closely involved with the many anomalies thrown up by the enactment of CASR Parts 21-35. A carefully selected CASA/Industry team (dunces from both sides excluded) did a very pragmatic job of sorting out said years of collected anomalies.
The MoD and Bored (Board) of Trade (before the CAA -- the Campaign Against Aviation) in UK agreed about nothing, and the ARB always threw in their two bob's worth.
Tootle pip!!
