SECTION V
the airplane back and forth with the rudder centered to determine that the
plane follows a perfectly straight line. The turning arc of the nose wheel is 30
degrees in either direction and is factory adjusted at stops on the bottom of
the forging. The turning radius of the nose wheel is 13 feet.
The steering arm stops should be carefully adjusted so that the nose
wheel reaches its full travel just after the rudder hits its stops. This guarantees
that the rudder will be allowed to move through its full travel.
Incorporated with each gear assembly are micro-switches. The down
switches are connected individually to green indicator lights on the
instrument panel and close when the gear is locked down. The up switches are
in series-parallel and open after each gear is fully up. When this circuit opens.
the yellow gear in transit light goes out. The micro-switches must be adjusted
carefully so that contact is made just as the gear reaches the required position.
The gear position lights are dim when panel lights are on.
Located in the control quadrant below the throttle are two micro-
switches. These switches activate the warning horn and the red light on the
instrument panel under the following conditions:
I. Gear up and power reduced below approximately 14" of manifold
pressure.
2. On aircraft equipped with the backup gear extender. if the sys-
tem has extended the landing gear and the gear selector is UP.
except at full throttle.
3. Gear selector switch in UP position while on the ground.
On aircraft NOT equipped with the backup gear extender. an additional
switch is installed which activates the warning horn and light whenever the
flaps are extended beyond the approach position (10°)and the landinggear
are not down and locked.
On the left oleo is a micro-switch which prevents the gear from retracting
if the oleo is compressed. i.e. on the ground.
