In Australia there is a long standing tradition that practice stalls must be conducted high enough to permit recovery by 3000 ft agl.
Folks,
And for damned good reasons, too, few GA aircraft are as reliable in recovery as a glider from UAs.
There is no regulation that prohibits you from dying, either, but it is still a bloody good idea,
An example, a rare but potentially deadly occurrence, it happened again quite recently ---- a C-152 got into a flat spin, from what started as a stall off a steep climbing turn type training exercise.
Most common GA aircraft are relatively benign most of the time, but not guaranteed benign all of the time.
Many will well recall their experiences in the Traumahawke --- there were so many complaints and incidents, the FAA eventually re-certified the aircraft, the results were "interesting".
Tootle pip!!
