4.37 TURBULENT AIR OPERATION
In keeping with good operating practice used in all aircraft, it is
recommended that when turbulent air is encountered or expected, the airspeed
be reduced to maneuvering speed to reduce the structural loads caused by
gusts and to allow for inadvertent speed build-ups which may occur as a result
of the turbulence or of distractions caused by the conditions.
4.39 LANDING GEAR
The pilot should become familiar with the function and significance of the
landing gear position indicators and warning lights.
The NAV LIGHT switch must be off to obtain full
intensity gear lights during daytime flying. When
aircraft is operated at night and NAV LIGHT
switch is turned on, gear lights will automatically
dim.
The red gear warning light on the instrument panel and the gear warning
horn operate simultaneously in flight when the throttle is reduced to where
the manifold pressure is approximately 14 inches of mercury or below, and
the gear is not in the DOWN position. The red gear warning light and horn
will also operate simultaneously on the ground when the battery master switch
is ON, the gear selector swtich is in the UP position, and the throttle is in the
retarded position.
The three green lights on the instrument panel operate individually as
each associated gear is locked in the extended position.
When the Emergency Landing Gear Extension Procedure (paragraph
3.31) is performed for training purposes, the hydraulic pump must be
deactivated by pulling the LANDING GEAR PUMP circuit breaker in order
for the procedure to extend the gear. Upon completion of the procedure,
reset the LANDING GEAR PUMP circuit breaker to resume normal
operation of the system. Verify that the emergency gear extension lever is
returned to the normal/up position.
