The Walleye MOAT also requires at least three
persons and a DSM-77 test set. The DSM-77 test set
projects a test image to be received by the Walleye.
With the cockpit switches ON, as listed in the
checklist, the Walleye dome cover removed, and the
tester mounted on the weapon and switched to LIGHT,
a display appears on the aircraft monitor. When the
tester is switched to LIGHT-MOTION, the image
moves from side to side, diagonally, or up and down,
depending upon the position of the tester. The tester
control assembly is rotated around the foundation
assembly during the testing process. During each
position test, the person in the cockpit pulls the trigger
switch and the weapon's television camera will lock on
to one of the target dots and follow it as it moves. As
each test is completed for each weapon loaded, the
dome cover should be replaced.
WARNING
During MOAT, or any other test being
performed after weapons have been loaded
on the aircraft, the MASTER ARMAMENT
switch must NEVER be placed in the ON
position.
When performing aircraft release and system
control checks, you should always use the step-by-step
procedures (checklist) provided in the aircraft loading
manual. A few safety precautions must be observed
when performing aircraft release and system control
checks. These precautions are listed below.
1.
Before you begin an aircraft release and system
control check, make sure the aircraft is parked
in a designated area, secured, and electrically
grounded.
2.
Before you apply external electrical power to
the aircraft, make sure all cockpit switches
have been positioned to OFF, NORMAL, or
HOLD.
If
required,
apply
external
air
conditioning.
3.
Release and control system checks will not be
performed with weapons loaded on the aircraft.
Checks may be performed with airborne stores
(fuel tanks, empty MERs/VERs, pods, etc.)
installed on the aircraft stations, provided
cartridge retainers, breech caps, and ejector
cartridges are removed.
4.
Test equipment should only be used by
personnel who have become qualified through
an established qualification and certification
program.
Stray voltage checks are normally performed with
the weapon loaded on the aircraft, but they are made
before making an electrical connection between the
weapon and the aircraft. Additionally, this check is
normally performed after the aircraft's engines have
been started and all aircraft preflight checks have been
completed. The stray voltage check is performed at the
last possible moment before the aircraft takes off. This
is to ensure that no voltage has been induced in the
aircraft firing circuitry from external sources, such as
the ship's radar. The launcher electrical safety pin must
not be removed until the aircraft is positioned on the
catapult for takeoff.
