View Full Version : More Than One V-LE (flight with gear extended speed)?

Is it possible to have more than a single V-LE (maximum airspeed with
gear extended without damage)? I know that some airplanes have more
than one V-LO (max gear operation speed), one for retraction and one
for extension. Perhaps there are configurations in which there are
different V-LE speeds, e.g., different CG or flap configurations.

Thanks.

Why would Vle be based on flap configuration or CG? Vle is usually
limited by the amount of speed the gear doors can handle when down and
sometimes the power of the gear motor to push the nosewheel out.
