What is the maximum flap-extended speed (Vfe) in KIAS?

• A. 83 KIAS
• B. 90 KIAS
• C. 85 KIAS
• D. 95 KIAS

Answer: (C)

Vfe is the maximum speed at which you may fly with the flaps in a given position. For the Cessna 152, the POH lists two flap settings and their Vfe limits: with flaps at 10 degrees, Vfe is 110 KIAS; with flaps at 20 degrees, Vfe is 85 KIAS. Since the maximum flap extension is 20 degrees, the governing Vfe is 85 KIAS. So the best answer is 85 KIAS. The other values don’t match the published Vfe for the full-flap condition.
