Indication; Protection - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

INDICATION

Electrical control is provided by a dual-leg-
end switchlight (Figure 7-24) for each thrust
reverser. The switchlights are located on the
reverse thrust control panel on the center
pedestal. Pushing a switchlight will arm the
system and illuminate the white ARMED leg-
end. With thrust levers at IDLE and weight on
wheels or wheel spin-up, unlatching and mov-
ing the thrust reverser lever from the stowed
position will cause the translating sleeve to
move rearward which will illuminate an amber
R E V E R S E R U N L O C K E D l i g h t o n t h e
glareshield (Figure 7-25). When the translat-
ing sleeves reaches full aft travel, the associ-
ated green REVERSE THRUST switchlight
(Figure 7-25) will illuminate to indicate that
reverse thrust can now be applied.
An amber UNSAFE TO ARM light forming
part of the ARMED switchlight (Figure 7-24)
will illuminate in flight to indicate that it is
unsafe to arm that thrust reverser system be-
cause (1) either the thrust reverse lever is not
in the fully stowed position or (2) the de-
ploy/stow switch is faulty (possibly giving a
permanent deploy command). Arming the sys-
tem with the UNSAFE TO ARM light illumi-
nated could result in immediate deployment
of that thrust reverser at touchdown. On the
ground this light will illuminate if the asso-
ciated reverser was not armed and the thrust
reverser lever is actuated.
The amber REVERSER UNLOCKED light
(Figure 7-25) will illuminate if (1) the trans-
lating sleeve is not stowed, (2) the pneumatic
brake is released, (3) the mechanical lock is
disengaged, and (4) the translating sleeve has
moved rearward more than 1 inch.

PROTECTION

General
The thrust reverser protection system includes
autostow, emergency stow, and a mechanical
thrust lever retard system.

Autostow
If a REVERSER UNLOCKED light illumi-
nates in flight, an electrical signal is auto-
matically sent to pneumatically stow the
reverser. If it is successful, the REVERSER
UNLOCK light extinguishes.
