In a spin, are both wings stalled?

In a spin, both wings are indeed stalled, which is why the correct answer indicates that both wings are stalled during the spin maneuver. A spin is characterized by an uncoordinated flight condition where the aircraft experiences a rapid rotation around its vertical axis, and this occurs as a result of one wing having a higher angle of attack than the other.

When one wing stalls, it generates less lift than the other, causing the aircraft to begin to yaw towards the lower-lift wing. However, for the airplane to maintain the spin, both wings are stalled; the airflow over both wings is disrupted, which leads to a significant reduction in lift and an inability to regain control without corrective input.

In terms of understanding the dynamics of spins and stalls, this comprehensive stall condition is critical because recovering from a spin generally requires specific recovery techniques that acknowledge that both wings are in a stalled condition, which is essential for a safe flight operation.
