Performancespeed limitations
Never Exceed Speed (Vne)
Never Exceed Speed (VNE) is the absolute maximum speed at which an aircraft may be safely flown, marked by a red line on the airspeed indicator (ASI). Operating above this speed may result in immediate structural failure, flutter, or loss of control. It represents the extreme structural limit of the airframe under dynamic pressure.
Key Points
- •V<sub>NE</sub> is represented by a solid red radial line on the ASI.
- •V<sub>NE</sub> must never be exceeded under any operation or circumstance.
- •Exceeding V<sub>NE</sub> risks catastrophic structural failure due to the dynamic pressures and flutter loads imposed on the airframe.
Exam Relevance
Identifying ASI markings and understanding the catastrophic consequences of exceeding Vne is a fundamental safety requirement tested in aerodynamics and performance.
