At what altitude does the prohibition on spins end?

The prohibition on spins typically ends at an altitude of 22,000 feet. This regulation is rooted in safety protocols and operational considerations within aviation to ensure that maneuvers like spins, which can be dangerous and difficult to recover from, are performed only at altitudes where recovery is feasible and does not compromise flight safety.

The rationale for setting this specific altitude is that at lower altitudes, there is less time and space for recovery from a spin. Once an altitude of 22,000 feet is reached, pilots are generally considered to have enough vertical room to recover safely should a spin occur, allowing for better reaction time and more options for recovery techniques. This altitude has been established as part of training and regulatory guidance in both military and civilian aviation environments to instill safe practice among pilots.
