Which Way Will It Go?

For many, predicting the direction in which an airplane will spin is a Fools Errand-any spins should be avoided in the first place. But understanding how a spin develops and how control deflections help determine the spin direction also can help us avoid them.

Key Takeaways:

• Spins develop when an airplane's wing exceeds its critical angle of attack (stalls) while simultaneously experiencing a yawing moment, often initiated by an uncoordinated turn or rudder input.
• The spin's direction is determined by the more fully stalled wing, which lowers and rotates the aircraft in the direction of the initial yaw.
• Avoiding stalls, particularly when the aircraft is yawing or in an uncoordinated turn, is crucial for preventing spins.
