electrical power can be applied at the external power
receptacle on the left side of the forward fuselage. This
is easily accessible from the deck level. The external
power connector connects 115/208-volt, three-phase,
400-hertz ac external power to the ac bus. When
external power is not available, the aircraft has an
auxiliary power unit (APU) to drive either of the aircraft
generators for functional checkout of the aircraft
system.
The systems and subsystems of the F/A-18 aircraft
armament system are discussed in the following text.
The aircraft armament system, basic controls, and
components all function in relation to each other.
Ground Power Control Panel Assembly
The ground power control panel assembly has four
toggle switches. Three of these switches control the
application of external power to avionic and instrument
systems. This prevents excessive equipment operating
time because of other unassociated ground operations.
The EXT PWR (external power) switch is a
three-position switch used to apply electrical power to
the aircraft. In the NORM (normal) position, electrical
power is supplied to the aircraft. In the OFF position,
no power is supplied to the aircraft. The RESET
position resets power for the external monitoring circuit
when there is a temporary overload. Switch 1 is a
three-position switch with B ON to provide enabling
power to the mission computers. Switch 2 is a
three-position switch with B ON to provide enabling
power to the digital display indicators (DDIs). The
B ON switch also enables power to the aircraft radar.
Switch 3 is a three-position switch with B ON to provide
enabling power to the armament computer stores
management panel (SMP), AN/AWW-4 system,
HARM system, and the AN/ALE-39 system.
Landing Gear Control Handle
In the DN position, the LDG GEAR control (fig.
15-12) disables normal weapon release, launch, and fire
signals. In the UP position, 28-volt dc power is applied

The F/A-18 is a dual-mission, fighter bomber naval aircraft.
The F-14 aircraft incorporates the AN/ALE-39 chaff dispensing system.
When the landing gear handle is in the down position on the F-14 aircraft, the
armament safety override switch is used to bypass the open loading gear safety
circuit.
The F-14 aircraft can hold a maximum of six AIM-54 missiles.
The fuselage stations of the F-14 aircraft used to suspend AIM-7 missiles include
stations 3, 4, 5, and 6.
The F-14 aircraft can hold a maximum of four AIM-9 missiles.
The stations of the F-14 aircraft that are used to carry Sidewinder missiles include
stations 1A, 1B, 8A, and 8B.
The HIGH and LOW rates of fire for the M61A1 gun, when it is mounted in the
F-14 aircraft, are HIGH—6,000 and LOW— 4,000 rounds per minute.
The burst selector switch on the F-14 aircraft limits the number of rounds that are
fired per burst.
The four jettison modes of the F-14 aircraft areas follows: (1) emergency,
(2) ACM encounter (3) selective, and (4) auxiliary.
The emergency jettison mode is the only one controlled by the pilot.
