What is indicated by the top of the white arc on the airspeed indicator?

• A. Vne
• B. Vso
• C. Vfe
• D. Vno

Answer: (C)

The top of the white arc on the airspeed indicator indicates Vfe, which stands for the maximum flap extended speed. This is the highest speed at which an aircraft can safely be flown with the flaps fully extended. Exceeding this speed while the flaps are deployed can lead to potential control issues or structural damage to the aircraft, as flaps alter the aerodynamics significantly. Pilots must be aware of this speed to ensure safe operation during approaches and landings when the aircraft is configured for maximum lift and drag with flaps extended. Understanding Vfe is crucial for maintaining safety and performance standards while flying.
