What is the term for the highest speed permissible with wing flaps in a prescribed extended position?

• A. Flap Extended Speed
• B. Flaps Maximum Speed
• C. Flap Down Speed
• D. Flap Safe Speed

Answer: (A)

Flap extended speed is the maximum airspeed at which you can fly with the flaps in the extended position. This limit protects the flap mechanism and the wing from aerodynamic loads and possible damage when the flaps are deployed. The term shown in flight manuals and on performance charts is the standard way to specify this limit, often noted as V_FE. So, the phrase “Flap Extended Speed” best matches what pilots look for as the highest permissible speed with flaps out. The other phrases aren’t standard terms used in official data, and don’t convey the specific limit for extended flaps.
