What is the minimum altitude required for intentional spin entry?

The minimum altitude required for intentional spin entry is 13,500 feet Mean Sea Level (MSL). This altitude is established to ensure that pilots have sufficient vertical space to safely recover from a spin and to avoid any risk of reaching the ground before regaining control of the aircraft. At this altitude, pilots can effectively manage the spin recovery procedures, which involves a clear understanding of the aircraft's behavior and adequate time to restore it to a stable flight condition. Selecting a sufficient altitude is crucial for safety, as it provides a buffer zone to perform necessary maneuvers, confirm recovery techniques, and assess the aircraft's response without the pressure of immediate ground impact.

Choosing an altitude lower than 13,500 feet could compromise the pilot's ability to recover from the maneuver, making it a critical component of spin training and operations in the T-6 aircraft.
