Which speed is indicated by the abbreviation Vf?

Maximum landing gear extension speed
Minimum control speed with critical engine inoperative
Design flap speed
Lift off speed

The correct answer is: Design flap speed

The abbreviation Vf refers specifically to the design flap speed, which is the maximum speed at which flaps can be safely extended for a given configuration of the aircraft. This speed is critical in ensuring that the aircraft maintains optimal performance during approaches and landings while utilizing flaps, enhancing lift and controlling stall behavior. Understanding Vf helps pilots operate safely within the aircraft's limitations and use flaps effectively to manage descent and landing phases. The other options represent different speeds with specific functions or limitations during flight operations, but they do not define Vf directly. Recognizing the distinct roles of each speed is vital for safe and effective flight training, particularly when preparing for certification as a flight instructor.
