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
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 aircrafts 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 ships radar. The launcher electrical safety pin must
not be removed until the aircraft is positioned on the
catapult for takeoff.
REVIEW NUMBER 3
Q1. How many persons are required to perform a
MOAT on a Sidewinder missile?
Q2. In what position should the MASTER ARM
switch be set when a MOAT is being conducted
on a naval aircraft?
