What is Vfe (maximum flap-extended speed)?

• A. 90 KIAS
• B. 80 KIAS
• C. 100 KIAS
• D. 85 KIAS

Answer: (D)

Vfe is the maximum speed you may fly with the flaps extended. For the Cessna 152, when the flaps are fully extended, the published Vfe is 85 KIAS. That means any flight with flaps down must stay at or below 85 knots to stay within the safe structural and aerodynamic limits. If you retract the flaps or use only partial extension, higher speeds are permissible, but the flap-extended limit remains 85 KIAS. The other speeds listed do not represent the full-flap Vfe for this aircraft.
