Some (most) military birds have what is called a 'SQUAT' switch. It is
a switch on a main gear oelo that is activated after bird is airborne
and strut extends. Is suppossed to prevent one from pulling gear on
ground (

Some. Those that use electrics to bring up the gear can do so. Some
the gear handle is just a hydraulic control. No squat switch because there
isn't any electrics involved in moving the gear.

The Navion (L-17) works that way too. It's not usually the take-off roll.
The common mistake is having the handle in the UP position when cranking
the engine. It only takes the pressure from the starter turing the engine to start the nose
wheel up (and the nose down).
