switch is used as an armament safety override to bypass the open landing gear safety circuit when the LDG GEAR handle is in the DN position. This lets you make func- tional checks of the system during ground maintenance. Missile Control System The missile control system consists of the controls and components you have already read about. It also contains the following missile system controls and components: Weapons status indicators Liquid (LIQ) cooling control panel Aft cockpit caution advisory panel The AIM-54 and AIM-7 missile fire control systems help to select, prepare, and launch AIM-54 and AIM-7 missiles. The AIM-54 is a long-range, semiactive, radar midcourse guided and active radar terminal guided missile. It operates in either the normal or boresight mode. The F-14 carries a maximum of six AIM-54 missiles-two are suspended from multipurpose pylons on stations 1B and 8B, and the remaining four at weapons rail stations 3R, 4R, 5R, and 6R. The AIM-7 is a medium-range, semiactive, radar-guided missile. It also operates in either the normal or boresight mode. The F-14 carries a maximum of six AIM-7 missiles—two are suspended from multipurpose pylons on stations 1B and 8B and four at semisubmerged fuselage stations 3, 4, 5, and 6. The AIM-9 fire control system enables selecting, preparing, and firing of the AIM-9 (series) missiles. The AIM-9 missile is a supersonic, short-range, air-to-air intercept missile that uses passive infrared for target detection and guidance. The F-14 carries a maximum of four AIM-9 missiles-one missile each on stations 1A, 1B, 8A, and 8B. The weapons status indicators are located on the ACM panel. They notify the pilot of the weapon status of the AIM-9 missiles on stations 1A, 1B, 8A, and 8B. The Sidewinder cool (SW COOL) switch (fig. 15-1) is a two-position, push-button switch on the ACM panel. This switch is used to generate the AIM-9 missile cool signal to cool the missiles. When in the ACM encounter mode, AIM-9 missile cooling is automatically selected, regardless of the SW COOL switch position. The throttle quadrant, located on the left side console of the forward cockpit, contains the CAGE/SEAM push-button switch for initiating the Sidewinder expanded acquisition mode (SEAM) lock-on command. The pilot presses the CAGE/SEAM push-button switch when the missile is locked on the target, as indicated by the AIM-9 tone in the pilot headset. The SEAM LOCK advisory indicator, located on the ACM panel, lights to notify the pilot that the AIM-9 missile selected is locked on the target. A tone volume control panel with an SW potentiometer, located on the pilot’s left side console, controls the AIM-9 tone to the pilot’s headset. Multiple Weapons Release System The multiple weapons release system has basic controls and components and multiple weapons system controls and components. They are discussed in the following paragraphs. The bomb release and rocket control systems enable selecting, preparing, and delivering of the air-to-ground stores. Weapons that can be carried on stations 3R, 4R, 5R, and 6R range from general-purpose bombs of various sizes to CBU, and GBUs. M61A1 20-MM Automatic Gun Fire Control System The M61A1 20-mm automatic gun fire control system enables selecting, arming, and firing of the gun. Depending upon the mission objective, the gun fire control system can be operated in an air-to-ground (A/G), air-to-air (A/A), or air combat maneuver (ACM encounter) mode. Two attack modes of operation are available—computer pilot attack mode and manual attack mode. The computer pilot attack mode operates with the weapon control system, command signal decoder system (CSDC), and the vertical display indicator system to display target data. The manual attack mode is used primarily as a backup mode to provide a manually controlled sight reticle if a system malfunction occurs. GUN RATE SWITCH. The GUN RATE switch (fig. 15-1) is located on the ACM panel. It is a two-position, push-button, indicator switch that selects HIGH (6,000 rounds per minute) or LOW (4,000 rounds per minute) rate of fire. This switch is only active in the A/G and A/A modes. A/G GUN SWITCH. The A/G GUN switch (fig. 15-2) is located on the armament control indicator panel. It is a two-position toggle switch that enables or inhibits a mixed bomb and gun mode operation. The MIXED position enables bomb and gun mode operation while the OFF position inhibits it. GUN CONTROL UNIT. The gun control unit, located above the gun barrels, contains the BURST 15-4
