Hi there..

I have no idea about aviation so excuse me if this is a dumb question.

Why is that on planes the landing gear:

a) has such an unique interface relative to the other avionics. E.g Why
the long handle?
b) What is the purpose of the wheel at the end of the landing gear arm?


Cheers
Steve

What kind of airplane are you looking at Steve? Some gear handles are only
an electric switch that activates a valve and on others the handle moves the
valve itself. The wheel on the end is a symbol of what the handle does.
Flap handles are usually a flat blade. Helps reduce the accidental gear
retraction accident
