I remember an Examiner relating how he had to recover an aircraft from three ua's in the circuit after takeoff
In Australia there is a long standing tradition that practice stalls must be conducted high enough to permit recovery by 3000 ft agl. Nothing in the Regs of course. Some LSA flying schools still use that "rule" even though the average LSA will only lose 50 feet in a recovery. A competent student pilot in a Cessna 172 would lose maybe 100 feet.
Yet no such tradition applies to gliders where practice stalling is often done below 1500 ft agl. And with no power to aid recovery. Would be interesting to know is there a rule for glider pilots re minimum height to recover by when practicing stall recovery?
