Final answer:
The statement is generally false; the manual spin recovery mode is used to assist in spin recovery, not to prevent it. This mode is essential in many aircraft to regain control when automated systems are ineffective.
Step-by-step explanation:
The statement 'Selection of manual spin recovery mode (SPIN switch in RCVY) seriously degrades controllability, will prevent recovery from any departure or spin, and is prohibited' can be classified as False. In the context of aircraft operations, the SPIN or spin recovery switch is a tool available to pilots to assist in the recovery from spins. Its purpose is to allow manual control for spin recovery when autopilot or automated systems are not effective in resolving the spin condition.
It is not correct to say that selecting manual spin recovery mode will prevent recovery from any departure or spin. Rather, in some aircraft, it is a necessary step to regain control. Manufacturers provide procedures for spin recovery that usually include the use of manual spin recovery mode under certain conditions. The statement incorrectly suggests that such mode will degrade controllability to a level that prevents recovery and is prohibited, which is generally not the case.
However, it's important to note that not all aircraft are capable of or certified for intentional spin recovery, and in such cases, the statement might be true for that specific aircraft type. Pilots must always follow the procedures outlined in the aircraft's flight manual for recovery from unusual flight attitudes, including spins.
