position indicator. The amber LH FLT SPLR
and the RH FLT SPLR lights extinguish when
the spoilers are fully retracted and locked.
If either of the two PCU’s actuating a spoiler
panel should fail mechanically or hydrauli-
cally, the adjacent PCU is capable of actuat-
ing the spoiler.
GROUND SPOILERS
General
The ground spoiler on each wing is powered
by a single hydraulic actuator. Internal locks
in the actuator hold the spoiler retracted and
are hydraulically released for spoiler exten-
sion. Spoiler operation is controlled by a
switch on the center pedestal. The spoilers
are operative only on the ground and have two
operating positions: retracted and fully ex-
tended (45°).
Operation
The ground spoilers are armed for operation
by the GROUND SPOILER switch which re-
mains in the OFF position until armed for
takeoff (Figure 15-11) except for test.
