While I agree that practice recovering from "realistic entry" spins
and/or spiral dives is highly desirable, there are real problems with
trying to do so.

For example, my LS8-18 POH specifically states "Aerobatic flight not
approved". My club's Grob 103s are approved for spins, but the club
insurance policy prohibits doing them. There is one nearby commercial
operator who offers an introductory aerobatics course using a Blanik
L-13AC, but as he wants to get out of the flying business that option
won't be available much longer.
