The A/A weapon select switch selects the
Sparrow missile on the priority station when the
switch is in the FWD position. Each time the switch
is depressed, the priority station changes. SEL is
displayed on the DDI underneath the SP acronym of
the station selected. An X is superimposed through
the SP when the missile is not tuned. The X
disappears when the missile tunes. The RADAR
switch is located on the sensor control panel.
AIM-9 Sidewinder Fire Control System
The Sidewinder fire control system provides the
aircraft with the capability for firing a Sidewinder
missile. Control of the missile is provided through
the SMP. No voltage is supplied to fire the missile
until the trigger switch is pulled. Weapon selection is
made by the A/A weapon select switch on the aircraft
controller grip assembly. Tone volume is controlled
by the WPN VOL switch. The system consists of the
IR COOL switch, trigger switch, and the armament
basic controls and components.
The A/A weapon select switch selects the
Sidewinder missile on the priority station when the
switch is in the DOWN position. Each time the
switch is depressed, the priority station changes. SEL
is displayed on the DDI underneath the SW acronym
of the station selected. The WPN VOL switch is on
the intercommunication amplifier control panel
assembly.
The IR COOL switch is a three-position switch on
the map gain control panel assembly. When the
switch is in the OFF position, coolant is disabled to
the seeker heads unless weight is off the wheels, the
MASTER switch is in the ARM position, and the
station is selected. In the NORM position, coolant is
enabled to all seeker heads when the weight is off the
wheels. In the ORIDE position, coolant is enabled to
all seeker heads when power is applied to the aircraft.
M61A1 20-mm Gun System
The M61A1 20-mm gun system provides the
aircraft with the capability for firing the gun. The
system enables selecting, arming, and firing.
Depending upon the mission objective, the gun can be
operated in the A/A or the A/G computer modes. In
the A/G mode there are two submodes. The two
submodes are the continuously computer impact point
(CCIP) and the manual (MAN) modes. There are
three A/A modes. These are the director, disturbed,
and the cage modes. Control of the gun is supplied
through the SMP. No voltage is supplied to the gun
until the trigger switch is pulled.
AN/ALE-39 Decoy Dispensing System
The AN/ALE-39 decoy dispensing system
provides the aircraft with the capability for dispensing
chaff and flares. The decoy rounds are contained in
two dispensers at the fuselage underside area.
Control is supplied through the SMP. The system
consists of the dispenser/ECM control panel, engine
throttle lever grip assembly, left console DISP switch,
the ALE-39 programmer, two AN/ALE-29A
dispensers, and the armament system basic controls
and components.
ANTISUBMARINE WARFARE
WEAPONS SYSTEMS
Learning Objective: Recognize various
weapons systems on ASW type aircraft.
Antisubmarine warfare (ASW) is becoming an
ever broadening field.
Our ASW capabilities have
been improving constantly. As a senior avionics
technician, you must play the key role in maintaining
the ASW platform used for in-flight launching of
search and kill stores. When launched at precise
intervals and locations and in conjunction with the
aircraft’s electronic data processing equipment, these
stores provide accurate information for detecting
enemy submarines. The kill stores consist mainly of
torpedoes, mines, bombs, rockets, and guided
missiles.
The remainder of this chapter discusses the
basic ASW system, the P-3C and S-3A search store
systems, the helicopter search store systems, the
P-3C and S-3A kill store systems, and the helicopter
kill store systems. Finally, the control systems for
release and control of search and kill stores are
discussed.
BASIC ASW WEAPONS SYSTEMS
The basic ASW weapons systems consist of the
equipment and accessories necessary for carrying and
releasing the search and kill stores.
