During the incipient stage of a spin, what typically happens?

During the incipient stage of a spin, the key event is that the aircraft begins to enter the spin process. This stage occurs when the aircraft has lost its controlled flight, typically as a result of an uncoordinated maneuver or excessive yaw. In this phase, one wing begins to stall while the other wing may still have some lift, causing the aircraft to start a yawing motion. As the aerodynamic forces start to dominate, this leads to the development of a spin.

Understanding the dynamics of a spin is crucial for pilots, especially for a Certified Flight Instructor (CFI), as it allows for effective instruction on recovery techniques and safe flying practices. Knowing that the incipient stage is the beginning of an aircraft spin emphasizes the importance of recognizing and addressing the symptoms early to prevent progression into a fully developed spin.
