Which V-speed represents maximum flap extended speed?

1. Vfe

2. Vle

3. Vno

4. Va

The correct answer is: Vfe

The V-speed representing maximum flap extended speed is indeed Vfe. This speed is crucial in managing aircraft performance when flying with flaps extended, as exceeding Vfe can lead to increased drag and potential structural risks to the wing and flap system. Understanding Vfe helps pilots safely operate the aircraft during critical phases of flight, such as landing and approach. It effectively defines the maximum airspeed at which the flaps can be safely deployed and used without risking damage or compromising control effectiveness. This operational boundary is vital for maintaining safety, especially during maneuvers that involve a higher angle of attack. In context, Vle refers to maximum landing gear extended speed, which is unrelated to flap usage. Vno is the maximum structural cruising speed, beyond which the aircraft should not be flown in turbulent air; while Va is the design maneuvering speed, allowing for coordinated movements without excessive control deflections. Each of these speeds serves a specific purpose, but when it comes to flaps, Vfe is the critical value to adhere to.
