2025年1月15日 · VNO, the maximum structural cruising speed, is the highest speed that you can safely fly in smooth air. VNO is marked by the upper limit of the green arc on the airspeed indicator. If you’re above VNO (in the yellow arc or “caution range”) and you encounter air that is not smooth, you could cause damage to the aircraft.

2010年8月12日 · At the top end of the Green Arc, is the Vno. Vno As the Green Arc is the Normal Operating Range, the top of the green arc is the Velocity (V) of Normal (n) Operations (o) or Vno. This is the maximum structural cruising speed. Operation of the Aircraft at the Vno speed, and lower, is within the certified range for operations within gusts.

Vno：最大结构巡航速度. 飞机在扰动气流中最大速度，对应空速表绿色末端（黄色起始端） Vne：极限速度. 对应空速表黄色末端（红线） 以下速度写在手册和QRH上，不在空速表. Va：机动速度. 大于此速度，避免副翼、方向舵、升降舵全行程操作. Vb：颠簸穿越速度

2022年8月30日 · VNE — Never exceed speed. This is the maximum speed an aircraft can fly without risking structural damage. This is similar to VMO above, it really depends on the type of aircraft in question. VNO — The maximum structural cruising speed. This is the fastest speed an aircraft can fly without risking damage to the airframe.

2024年10月27日 · VMO is the absolute maximum operating speed in smooth air, while VNO is the speed limit for normal operation, particularly in turbulent or rough air. Exceeding VNO in turbulence can lead to structural stress, while exceeding VMO can lead to more immediate structural risks regardless of turbulence.

2017年8月14日 · Formula for determining VA at less than max landing weight: VA2 equals VA multiplied by current weight divided by max landing weight. — Maximum speed for airbrake extension. — Maximum speed for...

2024年10月14日 · VNO (Maximum Structural Cruising Speed): The highest speed for normal operations; flying above this is allowed only in smooth air with caution. VNE (Never Exceed Speed): The absolute maximum speed the aircraft can safely fly; exceeding this can lead to structural damage.

2025年1月2日 · Vno: Maximum structural cruising speed. The speed that should not be exceeded except in smooth air and with caution. Vne: Never exceed speed. The maximum speed at which the aircraft should never be operated. Vmc: Minimum control speed with the critical engine inoperative. V1: Takeoff decision speed. The speed beyond which takeoff should no ...

2013年6月2日 · Vne －－ 永不超过的速度。 禁止在这个速度以上运行，因为它可能导致损坏或者结构失效。 设计机动速度Va －－ 这是乱流速度和突然操纵的最大速度。 如果在飞行期间，遭遇乱流或者严重的紊流，要降低空速到机动速度或者以下来最小化飞机结构上的应力。 考虑重量的时候参考这个速度很重要。 例如，当飞机有较重的载荷时Va可能是100节，但是载荷轻的时候就只有90节。 起落架操作速度 Vlo －－ 如果飞机装配了可收放起落架的话，这个速度就是伸出或者 …

Vno – Safe Structural Cruising Speed. The safe structural cruising speed is the maximum speed at which it’s safe to operate without the fear of causing damage to the aircraft. While it can also be safe to travel above Vno, it is only safe to do so in smooth air when no turbulence is present.
