What does Vne stand for?

Vne stands for "Never Exceed Speed." This is a critical airspeed limitation in aircraft operations, indicating the maximum velocity an aircraft should not exceed under any circumstances. Exceeding this speed can lead to structural damage to the aircraft, loss of control, or potentially catastrophic failure, as it often occurs in turbulence or extreme maneuvers. Understanding and respecting Vne is essential for safe flying practices, as it helps pilots maintain aircraft integrity and operational safety during flight.

The other terms mentioned are related to performance criteria but serve different purposes: best angle of climb refers to the optimal climb rate for gaining altitude over distance, maximum flap extended speed relates to the highest speed at which flaps can be safely deployed, and stall speed in landing configuration pertains to the minimum speed at which an aircraft can maintain controlled flight during landing. These are important for various operational scenarios, but they do not define Vne.
