The left squat switch also connects to the left stall warning test,
the outboard wheel anti-skid generators, and the landing gear
control. The right squat switch connects to the right stall warn-
ing test, the inboard wheel anti-skid generators, and the land-
ing gear control.
The main gear and the nose gear down-and-locked switches
have several functions in addition to controlling the respective
green LOCKED DN lights.
If the main down-and-locked switch does not sense a down-
andlocked condition, the aural warning system is enabled, the
inboard gear doors will not close, and the landing/taxi light for
the respective gear will not operate.
If the nose gear down-and-locked switch does not sense a
downand-locked condition, the aural warning system is
enabled, the nose gear UNSAFE light will not extinguish, and
the amber ENG SYNC light will not illuminate if the engine sync
is on.
The landing gear aural warning horn sounds and the three red
UNSAFE lights illuminate if the landing gear is not down-and-
locked, if the aircraft altitude is below 14,000 ±500 ft, and either
throttle lever is retarded below approximately 55 to 60% N
1. On
aircraft with the FC-530 autopilot, airspeed must also be
below 170 KIAS.
If the flaps are extended beyond 25× and the gear is not
downand- locked, the horn sounds and cannot be silenced.
