Emergency Extension
General
The emergency gear extension system is pneu-
matically operated by a bottle charged to
1,800–3,000 psi with dry air or nitrogen located
in the nose compartment. Bottle pressure is
shown on the direct-reading EMERGENCY AIR
indicator on the copilot’s instrument panel
(Figure 14-8). The bottle also provides pressure
for emergency braking.
Prior to using the system, the landing gear
selector switch (see Figure 14-1) should be
placed in the GEAR DOWN position, and the
GEAR circuit breaker on the right essential bus
should be pulled. This will prevent inadvertent
gear retraction subsequent to a successful exten-
sion. The system is activated by depressing the
emergency gear extension lever on the left side of
the pedestal (Figure 14-9). The lever has a ratchet
to keep it in the down position, once activated,
and can be raised only by pulling an adjacent
metal tab while lifting the lever.
