ARROW
PROCEDURES
A. SYSTEM OPERATIONS
1. The stall-warning system is inoperative with the master switch off.
2. The electric fuel pump must be on for
both landing and takeoff.
3. Some aircraft are equipped with an airspeed
-
power sensing system (backup gear
gear extender
(
which extends the landing gar under low airspeed
-
power conditions*
even though the pilot may not have selected gear down. This system will also prevent
retraction of the landing gear by normal means when the airspeed
-
power values
are below a predetermined minimum. (See Item
5,
Procedures Section.) To override
this system or to hold the emergency gear lever in the override up position with-
out maintaining manual pressure on the emergency gear lever, pull the lever full
up and push the latch pin in. To release the override, pull lever up to disengage
latch pin, then release lever. For normal operation, the pilot should extend and
retract the gear with the gear selector switch located on the instrument panel, just
as he would if the backup gear extender system were not installed.
*Approximately 105 mph IAS at any altitude, power off.
WARNING
Panel light dimmer switch must be off to obtain gear lights full
intensity during daytime flying. When aircraft is operated at night
and panel light dimmer switch is turned on, gear lights will
automatically dim.
4. Landing gear position indication and warning lights:
(a) The red gear warning light on the instrument panel and the horn operate
simultaneously when:
(1) In flight, when the throttle is reduced to where the manifold pressure is
approximately 14 inches of mercury or below, and the gear selector switch
is not in the down position.
(2) On aircraft equipped with the backup gear extender, when the system
has lowered the landing gear and the gear selector switch is not in the down
position and
the
throttle is not full open.
(3) On the ground, when the master switch is on and the gear selector switch
is in the up position.
NOTE
On aircraft which are 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 landing gear are not down and locked.
(b)
The three green lights on the instrument panel operate individually as each
associated gear is locked in the extended position.
