During a spin to the left, which wing(s) is/are stalled?

• A. Both wings are stalled
• B. Left wing only
• C. Right wing only
• D. Neither wing

Answer: (A)

In a spin, both wings are stalled. When an airplane or glider enters a spin, the angle of attack on both wings reaches the critical point and lift is lost on each wing. The rotation is then driven by unequal stall on the two wings—the wing that’s more deeply stalled creates the yaw that sustains the spin. In a spin to the left, you typically have the left wing more deeply stalled, but the right wing is still stalled too, so both wings are stalled overall. The other possibilities don’t fit because a single-wing stall or no stall at all wouldn’t produce a stable spin.
