4.5 EMERGENCY GEAR
OPERATION
An emergency hand pump is provided in case of
total electric pump failure or loss of fluid. The
emergency hand pump draws hydraulic fluid
from the bottom of the hydraulic power pack
reservoir. The hydraulic power pack electric
pumps have fluid pickup tubes that do not reach
the bottom of the hydraulic fluid reservoir. This
prevents the electric pump from being able to
pump all the fluid out of the system.
The remaining small reserve quantity of fluid
below the electric pump pickup tube is then
reserved exclusively for the emergency hand
pump. The quantity of reserve fluid below the
electric pump pickup tubes is sufficient to raise
or lower the landing gear with the hand pump
alone.
