What is the function of Vfe in flight operations?

Vfe indicates the maximum speed at which an aircraft can safely fly with the flaps extended. This is a critical piece of information for pilots, as exceeding this speed while the flaps are deployed can lead to excess aerodynamic stress on the aircraft and potentially cause structural failure or control issues. Understanding Vfe helps pilots manage flap use effectively during various phases of flight, particularly during approach and landing where flaps are typically extended to improve lift and decrease stall speed. By knowing the correct Vfe for the specific configuration, pilots can ensure they remain within safe operational limits, maintaining the integrity and handling characteristics of the aircraft.
