What airspeed limit is associated with the maximum flap extended speed?

The maximum flap extended speed, often referred to as Vfe, is a critical airspeed limit in aircraft operations that signifies the maximum speed at which the flaps may be safely extended. This speed varies depending on the aircraft type and can significantly influence flight safety and performance during approaches and landings.

For many aircraft, this limit often falls within a range that supports maintaining safe control of the airplane while flaps are deployed. The limit represented by the selected answer is 139 knots, which aligns with the typical specifications set by various aircraft manufacturers for models that require lower flap extension speeds to ensure proper aerodynamic performance and aircraft stability during low-speed maneuvers.

Understanding this airspeed limit is essential for pilots as exceeding Vfe while the flaps are extended could lead to adverse aerodynamic effects or potential structural damage, thereby emphasizing the importance of adhering to these operational limits during all phases of flight, particularly during approach and landing when flaps are commonly deployed.
