Which statement about stall speeds is true?

• A. Power-off stall with flaps UP is lower
• B. Power-off stall with flaps DOWN is lower
• C. Vne is lower than Vno
• D. Vfe is higher than Vne

Answer: (B)

Flaps increase wing camber and lift at lower speeds, so the airplane can reach the stall at a lower indicated airspeed when the power is reduced (power-off). That means the lowest stall speed occurs with the flaps down during a power-off stall. The other facts about Vne vs Vno and Vfe vs Vne aren’t correct for this scenario, since Vne is typically higher than Vno and Vfe is well below Vne. Therefore, the true statement is that power-off stall with flaps down is lower.
