is on the ground. Master arm power is removed whenthe handle is in the DOWN position, but is availablewhen the handle is in the UP position.ARMAMENT SAFETY OVERRIDESWITCH.— The armament safety override (ARMTSAFETY ORIDE) switch (fig. 7-7) is located in thenosewheel well. This switch is a magnetically heldclosed switch. The switch is used as an armamentsafety override to bypass the open landing gear safetycircuit when the LDG GEAR handle is in the DOWNposition. This switch enables technicians to performfunctional checks while the aircraft is on the ground.Missile Control SystemThe missile control system consists of the basiccontrols and components previously discussed, andthe following controls and components: the weaponsstatus indicators, the liquid (LIQ) cooling controlpanel, and the aft cockpit caution advisory panel.Multiple Weapons Release SystemThe multiple weapons release system comprisesthe basic controls and components, as well as themultiple weapons systems controls and components.M61A1 20-mm Automatic Gunfire ControlsystemThe M61A1 20-mm automatic gunfire controlsystem enables selecting, arming, and firing of thegun. Depending upon the mission objective, thegunfire control system can be operated in an air-to-air(A/A), air-to-ground (A/G), or air-combat maneuver(ACM encounter) mode.AN/AWW-4 Fuze Function Control SystemThis system is used to provide a high dc voltagefor the charging and arming of electrical bomb fuzes.It also provides voltage for the electrical initiation ofthe VT or proximity fuze. The faze is called a VTfuze because the original device contained vacuumtubes.Decoy Dispensing SystemsThe F-14 aircraft uses the AN/ALE-29A or theAN/ALE-39 decoy dispensing system to eject decoyrounds into the air. These rounds consist of chaffpackages or flares. Releasing these rounds allows theaircraft to evade air-to-air and surface-to-air attacks.The location of the decoy dispenser is shown infigure 7-8.Jettison SystemThe jettison system enables the jettisoning ofcertain external stores. There are four jettison modes:1. Emergency—Pilot controlled.2. ACM encounter—NFO selected, pilot controlled.3. Selective—NFO controlled.4. Auxiliary—NFO controlled.The NFO is the person in the back seat of theaircraft. The NFO selects and controls the jettison byusing the armament control indicator located in the aftcockpit (fig. 7-2). In all modes, arming and fuzing areFigure 7-7.-Armament safety override switch.7-4
