Section III - SYSTEMS DESCRIPTION
THRUST REVERSERS
DESCRIPTION
The thrust reverser assembly consists of clamshell type doors which, when stowed, form the final
section of the engine exhaust nozzle. The reverser doors are held in the stowed positions by a latching
system until released by the sequenced actuation of a series of switches and relays.
Two fan flaps within each installation are used to reduce the temperature at the clamshell doors while
in reverse mode; these are stowed and deployed in conjunction with the clamshell doors. Each thrust
lever has a solenoid operated baulk arrangement which mechanically prevents selection of reverse
thrust until the reverser doors are fully deployed. Each reverse thrust selector lever has a stop to limit
the thrust obtainable at the full reverse thrust position.
CONTROLS and INDICATORS
An electrical control panel, located on the lower section of the center instrument panel, provides L/H
and R/H THRUST REVERSER POWER switchlights which illuminate ARM or OFF. Amber UNLCK and
green REVRS annunciators are also provided on the panel. An amber REVERSER annunciator,
located on the MWS panel, illuminates to indicate the existence of a malfunction of either reverser.
ARM
Pushing this switch initiates a sequence, which upon completion makes sure the thrust reverser is ready
for deployment. The white ARM annunciator will illuminate when the ready for deployment sequence
has been completed.
The white ARM annunciator will only illuminate when the following conditions are satisfied:
1. Weight on airplane wheels.
2. Thrust lever at idle.
3. Hydraulic pressure available at reverser control valves.
