BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual page 379

CONTROLS AND INDICATORS
Controls
Landing gear operation is controlled with the
landing gear handle (Figure 14-8). The han-
dle is detented in both the UP and DN posi-
tions and must be pulled slightly toward the
pilot prior to movement.
A solenoid-operated locking device restrains
the handle when the airplane is on the ground,
preventing inadvertent movement of the han-
dle to the UP position. When airborne, the
weight-on-wheels (WOW) system completes
circuitry to disengage the lock, after which the
handle can be positioned to the UP position.
The DN LCK REL button, when moved down,
releases the solenoid lock whether the air-
plane is on the ground or in flight.

The MUTE HORN button, when pressed, mutes
the landing gear unsafe warning horn unless the
flaps are extended beyond the 30° position.
Indicators
Illumination of the green NOSE, LEFT, and
RIGHT position indicator lights above the
LDG GEAR control panel indicates landing
gear down and locked (Figure 14-9). Flashing
red lights in the landing gear handle indicate
that the landing gear is in transit.
With the landing gear down and locked, the
three green position indicator lights will be
illuminated and the red handle lights will be
extinguished. When the gear is up and locked,
none of these lights are illuminated.
