When do I need to slow down below maneuvering speed?

Asked by: 9581 views General Aviation

Although maneuvering speed is 108 KTs, but i never reach that speed.

if the power is high , and i pitch down, that way will reach 108.

but, i think its ok to get over that speed as long as under Vne.

But i got this question. please help. lol

    The short answer:  You need to be below Va in order to use full-scale control deflection on the aileron, elevator, or rudder.
     
    For some more detail, you can look here:

    You can fly above Va (Maneuvering speed). However, flying above Va may cause structual damage to the aircraft during abrupt maneuvers or heavy turbulence.
    Keep in mind that Va changes depending on the weight of the aircraft. It may be 108 kts @ maximum takeoff weight, but it could be significantly lower when the airplane is lighter.

    Another speed you may want to consider is Vno (Normal Operating). You should only fly above that speed in smooth air.

    The idea behind Va is that it’s the speed at which the airplane will stall before it exceeds its rated load factor. I.e. you’ll stall the plane but you wont’ bend it. That’s why Va goes down as the weight goes down–the stall speed goes down as weight goes down.
     
    If you are at or below Va (for the current weight), you (or the turbulence) can’t impose forces on the plane that exceed what it was built to handle.

    I had actually posted a video before on the subject of Va but in case you missed it here it is again
