Answer :
In aviation, to ensure safety during spin recovery exercises, the recommended altitude to recover no lower than is:
(C)1,500 feet AGL.
For maneuvers such as spins, the Federal Aviation Regulations suggest a recovery should be initiated at an altitude that will allow the airplane to recover no lower than 1,500 feet Above Ground Level (AGL). Therefore, the correct answer to this question is C) 1500 feet AGL. This recommendation is to ensure there is sufficient altitude to complete the recovery without the risk of impacting the ground. It's an essential safety margin that accounts for the altitude lost during the process of stopping the spin and stabilizing the aircraft.
