each gear) are green and will illuminate when each gear is
fully extended and locked.
When the gear unlocked light
and gear down lights are not illuminated, the landing gear
is in the UP and locked position.
The lights are push-to-
test type with rotatable dimming shutters.
LANDING GEAR WARNING HORN
The landing gear warning horn is controlled by the
throttles and the flap preselect handle.
The warning horn
will sound an intermittent note if either throttle is retard-
ed below approximately 12 inches Hg. manifold pressure with
the landing gear retracted or if the flap handle is lowered
past the 15° position with the landing gear in any position
except extended and locked.
The warning horn can be activat-
ed by either the flap handle or by throttle position as each
functions independently of the other.
The warning horn is
also connected to the
UP
position of the landing gear switch
and will sound if the switch is placed in the
UP
position
while the aircraft is on the ground.
NOTE
Do not pull landing gear warning circuit
breaker to silence horn as this would also
turn off the landing gear indicator lights
and prevent landing gear retraction.
LANDING GEAR HANDCRANK
A landing gear handcrank, see Figure 2-6, for manually
lowering the landing gear is located just below the right
front edge of the pilot's seat.
Normally the crank is folded
and stowed in a clip beside the seat.
To use the crank, tilt
pilot's seat aft (std) or raise pilot's seat (opt), pull
crank out from its storage clip and unfold it until it locks
in operating position.
The procedure for manually lowering
the landing gear is given in Section III.
To stow the crank,
push the lock release button on the crank handle, fold handle
and insert it in the storage clip.
