BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual page 402

When armed, the ground spoilers will deploy au-
tomatically if the following conditions are met:
• Wheel spinup has occurred, or both
channels of the WOW system indicate
that the airplane is on the ground.
• The thrust levers are advanced above
IDLE and then returned to IDLE, or the
flight spoilers are extended with both
throttles at lDLE or SHUT OFF.
Spoiler extension is verified by illumination
of the amber LH GND SPLR and the RH GND
SPLR lights on the glareshield. If the spoil-
ers fail to extend, or if there is a difference in
extension angle, the amber SPLRS INOP light
on the spoiler control panel illuminates and the
spoilers automatically retract.
Ground Spoiler Test
Place and hold the switch in the TEST position.
• After 2 seconds, the LH GND SPLR and
RH GND SPLR lights should illuminate.
• After 4 additional seconds, the SPLRS
INOP light should illuminate as the
LH GND SPLR and RH GND SPLR
lights extinguish.
Place the switch momentarily in the OFF
position, then in the ON position.
• Check that all ground spoiler system
lights are extinguished.

FLAPS
General
The flap system consists of two inboard and
two outboard flaps. The inboard flaps have
movable flap vanes that automatically extend
or retract as the flaps are actuated. The out-
board flaps have fixed vanes. When the flaps
are extended, movable panels in the wing are
positioned to direct airflow over the outboard
vanes and flaps.
The flaps are electrically selected and elec-
trically actuated by a power drive unit (PDU)
through a system of flexible shafts and me-
chanical actuators. The PDU contains two
electric motors, either one capable of flap op-
eration. The flaps are shown in Figure 15-12.
The flap control lever is detented in all oper-
ating positions: 0°, 20°, 30°, and 45° with a
gate at the 20° position only. Intermediate po-
sitions are not possible.
Flap system controls and indicators are shown
in Figure 15-13.
