You won't make aircraft aircraft drivers into aircraft pilots by teaching them spins IMO. Aircraft pilots don't need to learn how to enter and recover from a fully developed spin because this maneuver is of no practical value during non aerobatic flight.
Not true. I have had students unintentionally end up in spins by pulling too hard into avoidance turns - too much a G and 'flick', she departs controlled flight! No aerobatics involved. Full spin recovery required, though, due to the startled reaction of said studes.
Thorough and regular spin training makes for a
much better all-round pilot. IMAO.
(10000+ hours, a good chunk of it military; single and multi-engine prop, multi-engine turboprop, single and multi-engine jet, QFI , Staff QFI..... and now flying heavy scheduled airliners.)
