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

CONTROL

The thrust reversers are controlled by levers
(Figure 7-10) piggyback-mounted on the thrust
levers. The thrust reverser levers are latched
in the fully forward position. The latch must
be manually released by the pilot, allowing
each thrust reverser lever to be moved be-
tween three basic positions: stow (fully for-
ward), deploy (20° aft of full forward), and
reverse thrust which is a variable position.
Stow and deploy are fixed positions.
When the thrust reverser lever is unlatched,
then moved upward and aft, a solenoid is en-

gaged to prevent more than 20° of lever travel
while the air motor operates the ballscrew
jacks to drive the translating sleeve aft, ex-
posing the cascade vanes and closing the 10
blocker doors in the bypass duct. At this point,
a microswitch is operated to release the thrust
reverser lever lock solenoid. Further aft mo-
tion of the thrust reverser lever acts through
the FCU power lever to increase fuel flow and
provide proportionally more reverse thrust.
Figure 7-23 shows the CF34 engine in for-
ward thrust and reverse thrust configurations.
