What are the two types of spin recovery techniques?

The correct answer identifies the two primary types of spin recovery techniques: power-off recovery and power-on recovery.

Power-off recovery is used when an aircraft is in a spin that has developed due to a stall with the throttle at a low power setting, where the aircraft is essentially in a clean configuration without thrust aiding recovery. The technique typically involves reducing the angle of attack (by pulling back on the control yoke or stick), neutralizing the ailerons to avoid inducing more roll, and applying opposite rudder to counteract the spin. This type of recovery is critical, as it is the most common situation pilots face when spinning occurs.

Power-on recovery, on the other hand, is relevant when the spin develops with power applied, such as during a climb or approach with full-throttle conditions. In this scenario, recovery techniques involve managing the power settings and control inputs to restore the aircraft to a straight and level flight. This emphasizes the skill of recognizing how engine power can affect spin recovery dynamics.

Both techniques emphasize the importance of understanding how changes in power settings can influence the aircraft's behavior in a spin and provide frameworks for effective recovery, highlighting best practices for maintaining control during emergency situations.
