Which V-speed represents maximum flap extended speed?

1. Vno

2. Vfe

3. Va

4. Vs0

The correct answer is: Vfe

The speed that represents maximum flap extended speed is indeed Vfe. This speed is critical for pilots since it indicates the maximum airspeed at which the aircraft can safely fly with the flaps extended. Exceeding this speed could lead to increased aerodynamic drag and potential control difficulties, as the airflow over the wings and control surfaces changes with the angle of attack and configuration of the aircraft. Understanding Vfe is essential for safe aircraft operation during various phases of flight, particularly during approach and landing when flaps are typically deployed to improve lift at lower speeds. This knowledge helps pilots manage airspeed and configuration in a way that promotes safety and performance in a given flight scenario. The other choices relate to different aspects of flight parameters: Vno is the maximum structural cruising speed, Va is the design maneuvering speed, and Vs0 is the stall speed in the landing configuration, none of which pertain to the use of flaps specifically.
