“squat” switches, on the main gear shock
str ut, open the control circuit when the oleo
strut is compressed. The squat switches must
close to actuate a solenoid, which moves a
downlock hook on the LDG GEAR CON-
TROL switch to the released position. This
mechanism prevents the LDG GEAR CON-
TROL switch handle from being placed in
the UP position when the air plane is on the
g round. The downlock hook automatically
unlocks when the airplane leaves the ground.
The downlock hook disengages when the
airplane leaves the ground because the squat
switches close and a circuit is completed
through the solenoid that moves the hook.
In the event of a malfunction of the down-
lock solenoid or the squat switch circuit,
