ATF Advanced Tactical Fighter. Original program name for the F-22.
ATO Air Tasking Order. A planning document that lists every aircraft sortie and target for a given day’s operations. Preparation of the ATO requires careful “deconfliction” to ensure the safety of friendly aircraft. During Desert Storm the ATOs ran to thousands of pages each day.
Avionics General term for all the electronic systems on an aircraft, including radar, communications, flight control, navigation, identification, and fire control computers. Components of an avionics system are increasingly interconnected by a “data bus” or high-speed digital network.
AWACS Airborne Warning and Control System. Specifically used to describe the Boeing E-3 Sentry family, but also used generically to describe similar types used by other Air Forces.
Bandit Fighter pilot jargon for a confirmed enemy aircraft. An older term, still used by some English-speaking air forces, is “Bogey.”
Bar One sweep of a radar beam, typically a few degrees in altitude and 60 to 120 degrees in width.
BARCAP Barrier Combat Air Patrol. A fighter operation intended to prevent enemy aircraft from passing through a defined airspace. A BARCAP is typically established along the most likely enemy area of approach, involving relays of fighters that are continuously relieved in place.
BDA Bomb Damage Assessment. The controversial art of determining from fuzzy imagery and contradictory intelligence whether or not a particular target has been destroyed or rendered inoperative.
Bingo The point when an aircraft has just enough fuel remaining to return safely to a friendly base. At this point, a rational pilot will attempt to disengage, unless there is an extremely compelling reason to put the aircraft at risk.
BLU Air Force nomenclature for a “bomb” or “munition.”
Boresight Mode When a radar beam or electro-optical device is pointed straight ahead (12 o’clock).
BVR Beyond Visual Range; usually used in reference to radar-guided air-to-air missiles. “Visual range” depends on the weather, how recently the windscreen was cleaned and polished, and the pilot’s visual acuity, but against a fighter-sized target rarely exceeds 10 miles (16 km.).
BW Bomber Wing (traditionally Bombardment Wing).
C-130 Hercules Lockheed tactical transport. Four Allison T56 turboprops. Over two thousand of these classic aircraft have been built since 1955 and it is still in production. Hero of 1976 Israeli hostage rescue mission to Entebbe, Uganda. Many models and variants, including AC-130U gunship and EC-130H communications jammer. New C-130J under development has advanced avionics and new Allison T406 engine with six-bladed propellers. Standard transport has maximum takeoff weight of 175,000 lb./80,000 kg.
C-141 Starlifter Long-range heavy lift transport, built by Lockheed, entered service in 1964. Four TF33 turbofan engines. About 227 remain in service, subject to weight restrictions due to airframe fatigue. Equipped for in-flight refueling. Maximum takeoff weight 325,000 pounds.
C-17 Globemaster III Heavy-lift McDonnell Douglas transport designed for operation into short, unimproved runways. Four P & W F117 turbofan engines. Maximum takeoff weight 585,000 lb./266,000 kg. Advanced cockpit with flight crew of two plus enlisted loadmaster in cargo bay. Only forty aircraft currently funded.

C3I Command, Control, Communications, and Intelligence; the components and targets of information warfare. Pronounced “see-three-eye.”
Call Sign (1) An identifying name and number assigned to an aircraft for a particular mission. Aircraft in the same flight will usually have consecutive numbers. (2) A nickname given to an aviator by his/her squadron mates and retained throughout his/her flying career, often humorous.
Canard Small fixed or movable wing located forward of an aircraft’s main wing. This is the French word for “duck,” from an early French aircraft (c. 1910) that first used this feature and was nicknamed “the Duck.” Canard-type designs are generally very resistant to stalling.
Canopy The transparent bubble that covers the cockpit of an aircraft. Usually made of Plexiglas, or polycarbonate, sometimes with a microscopically thin layer of radar-absorbing material. Easily scratched or abraded by sand or hail. Ejection seats have a means of explosively jettisoning or fracturing the canopy to reduce the chance of injury during ejection.
CAP Combat Air Patrol, a basic fighter tactic that involves cruising economically at high or medium altitude over a designated area searching for enemy aircraft.
CBU Cluster Bomb Unit. A munition that is fuzed to explode at low altitude, scattering large numbers of “submunitions” over an area target. Submunitions can be explosive grenades, delayed-action mines, antitank warheads, or other specialized devices.
CENTAF The Air Force component of U.S. Central Command, including units deployed to bases in Kuwait, Saudi Arabia, and other states in the Gulf region. The Commander of CENTAF is an Air Force lieutenant general, who typically also commands 9th Air Force based at Shaw AFB, South Carolina.
CENTCOM United States Central Command, a unified ( joint service) command with an area of responsibility in the Middle East and Southwest Asia. Headquartered at McDill AFB, Florida, and generally commanded by an Army four-star general. CENTCOM normally commands no major combat units, but in a crisis situation it would rapidly be reinforced by units of the Army’s XVIIIth Airborne Corps, the U.S. Marine Corps, and Allied forces.
Chaff Bundles of thin strips of aluminum foil or metallized plastic film that are ejected from an aircraft to confuse hostile radar. A chaff cloud creates a temporary “smokescreen” that makes it difficult for radar to pick out real targets. The effectiveness of chaff depends on matching the length of the chaff strips to the wavelength of the radar.
Chop To assign a unit to the command of a different headquarters. For example, in a Middle Eastern crisis the 366th Wing might be chopped to CENTCOM (U.S. Central Command). Term is probably derived from Cantonese pronunciation of the Chinese word for a seal used to sign official documents. “In-chop” and “out-chop” designate the official dates that a unit arrives in or departs a particular theater of operations.
CinC Commander in Chief. Used to designate the senior officer, typically a four-star general or admiral in charge of a major command, such as CINCPAC (Commander in Chief of the U.S. Pacific Command).
CMUP Conventional Munitions Upgrade Program. U.S. Air Force initiative to develop new families of low-cost improved conventional bombs.
CONOPS Concept of Operations. The commander’s guidance to subordinate units on the conduct of a campaign.
CTAPS Contingency Tactical Air Control System Automated Planning System. A transportable network of computer workstations, linking various databases required for the generation of an Air Tasking Order.
CVW Carrier Air Wing. A force of Navy aircraft organized for operation from an aircraft carrier. Typically includes one fighter squadron, two attack squadrons, and small units of helicopters and anti-submarine, electronic warfare and early warning radar planes. U.S. Marine Corps air units may be assigned to a carrier air wing.
CW Continuous Wave. A type of radar that emits energy continuously, rather than in pulses.
DARO Defense Airborne Reconnaisance Office. A Pentagon agency created in 1992, charged with fixing the mess in U.S. airborne recon.

Drag The force that resists the motion of a vehicle through a gaseous or liquid medium. The opposite force is lift. Also the practice of cross-dressing in clothing of the opposite sex for informal squadron entertainment events.
DSCS Defense Satellite Communication System. A family of geosynchronous satellites and ground terminals ranging from 33-inch airborne
antennas to 60-foot ground dishes. The current generation, DSCS III, includes five satellites, providing global coverage. Some earlier DSCS II satellites are still operational.
E-2C Hawkeye U.S. Navy carrier-based twin-turboprop airborne early warning aircraft built by Grumman. Large radar in saucer-shaped rotating antenna housing. Entered service in 1964. Also operated by France, Israel, and Japan.
E/O Electro-optical. A general term for sensors that use video, infrared, or laser technology for assisting navigation or locating, tracking, or designating targets.
ECM Electronic Countermeasures. Any use of the electromagnetic spectrum to confuse, degrade, or defeat hostile radars, sensors, or radio communications. The term ECCM (electronic counter-countermeasures) is used to describe active or passive defensive measures against enemy ECM, such as frequency-hopping or spread-spectrum waveforms.
EF-111 Raven Electronic warfare version of the F-111 fighter bomber. Nicknamed “Spark ’Vark.”
ELINT Electronic Intelligence. Interception and analysis of radar, radio, and other electromagnetic emissions in order to determine enemy location, numbers, and capabilities.
Energy In pilot jargon, the sum total of kinetic energy (speed) and potential energy (altitude) that an aircraft or missile has at a given instant. The concept of “energy maneuverability” developed by Colonel John Boyd is a fundamental idea in air-to-air tactics. Turning and other forms of maneuvering quickly use up energy, making an aircraft vulnerable to an enemy with more energy. The faster an aircraft can accelerate, the more quickly it can regain lost energy.
FAC Forward Air Controller. Designates both the aircraft and the pilot with the dangerous mission of circling over a battlefield to locate targets and direct strike aircraft.
FADEC Full Authority Digital Engine Control. A computer that monitors jet engine performance and pilot throttle inputs and regulates fuel supply for maximum efficiency.
Flameout The unintended loss of combustion inside a jet engine, due to a disruption of air flow. This can be extremely serious if the flight crew is unable to restart the affected engine.
Flap A hinged control surface, usually on the trailing edge of a wing, commonly used to increase lift during takeoff and drag during landing.
Flare (1) A pyrotechnic device ejected by an aircraft as a countermeasure to heat-seeking missiles. (2) A pitch-up maneuver to bleed off energy, performed during landing, just before touching down.
FLIR Forward Looking Infrared. An electro-optical device similar to a television camera that “sees” in the infrared spectrum rather than visible light. A FLIR displays an image based on minute temperature variations in its field of view, so that hot engine exhaust ducts, for example, appear as bright spots.
Fur Ball A confused dogfight involving a large number of aircraft on each side. Derived from the cartoonist’s typical representation of fights between cats and dogs.
G force One G is the force exerted by Earth’s gravity on stationary objects at sea level. High-energy maneuvers can subject the aircraft and pilot to as much as 9 Gs. Some advanced missiles can pull as much as 60 Gs in a turn.
G-suit Aircrew garment with inflatable bladders connected to a pressure-regulating system. During high-G maneuvers the suit compresses the legs and abdomen to prevent pooling of blood in the lower body that might deprive the brain of oxygen, causing “gray-out” or, in extreme cases, GLOC (G-induced loss of consciousness).
GBU Guided Bomb Unit. General term for a class of precision-guided munitions.
GHz Gigahertz. A measure of frequency, 1,000,000,000 cycles per second.
“Glass Cockpit” Design that replaces individual flight gauges and instruments with multi-function electronic display screens. A few mechanical gauges are usually retained for emergency backup.
Goldwater-Nichols Common name for the Military Reform Act of 1986, which created a series of unified commands cutting across traditional service boundaries and strengthened the power of the Chairman of the Joint Chiefs of Staff.
GPS Global Positioning System. A constellation of twenty-two Navstar satellites in inclined Earth orbits, which continously broadcast navigational signals synchronized by ultra-precise atomic clocks. At least four satellites are usually in transit across the sky visible from any point on Earth outside the polar regions. A specialized computer built into a portable receiver can derive highly accurate position and velocity information by correlating data from three or more satellites. An encoded part of the signal is reserved for military use. A similar, incomplete Russian system is called GLONASS.
Green Flag A series of realistic Air Force training exercises conducted at Nellis AFB to evaluate doctrine, training, tactics, readiness, and leadership at the squadron and wing level.
HARM AGM-88 High Speed Anti-Radiation Missile, produced by Texas Instruments. Mach 2+ with 146 lb. blast-fragmentation warhead. Typically fired 35 to 55 miles from target, but maximum range is greater.
Have Blue Original Lockheed “Skunk Works” prototype for the F-117 Stealth fighter. Considerably smaller than the production aircraft, and still highly classified.
Have Nap AGM-142 heavy medium range (50 mi./80 km.) standoff air-to-ground missile. Developed by Israeli Rafael Company, and co-produced by Lockheed Martin.
Have Quick A family of jam-resistant secure airborne radios operating in the UHF band utilizing frequency hopping.
HEI High Explosive Incendiary. A type of ammunition commonly used with air-to-air guns.
HOTAS Hands on Throttle and Stick. A cockpit flight control unit that allows the pilot to regulate engine power settings and steering commands with one hand.
HUD Heads-Up Display. A transparent screen above the cockpit instruments on which critical flight, target, and weapons information is projected so that the pilot need not look down to read gauges and displays during an engagement. Current HUD technology provides wide-angle display of radar and sensor data.
HVHAA High Value Heavy Airframe Aircraft. Air Force term for a big, slow, vulnerable, and extremely valuable aircraft such as an AWACS or tanker that must be protected at all costs.
IFF Identification Friend or Foe. A radio-frequency system designed to reduce the risk of shooting down friendly aircraft. An IFF “interrogator” on one aircraft transmits a coded message intended for the IFF “transponder” on an unknown target. If the proper coded reply is received, the target is reported as friendly. If no reply is received, the target is reported as unknown. IFF codes are changed frequently in wartime, but lack of an IFF response is not enough to classify a target as hostile, since the transponder may be inoperative or turned off.
IIR Imaging Infrared. An electro-optical device similar to a video camera that “sees” small differences in temperature and displays them as levels of contrast or false colors on an operator’s display screen.
IL-76 Candid Russian four-turbofan heavy transport. Maximum takeoff weight of 375,000 lb./170,000 kg. Designed to operate from relatively short, unpaved runways. Exported to many Soviet client states.
ILS Instrument Landing System. A radio-frequency device installed at some airfields that assists the pilot of a suitably equipped aircraft in landing during conditions of poor visibility.
INS Inertial Navigation System. A device that determines location and velocity by sensing the acceleration and direction of every movement after the system is initialized or updated at a known point. Conventional INS systems using mechanical gyroscopes are subject to “drift” after hours of continuous operation. Ring-laser gyros sense motion by measuring the frequency shift of laser pulses in two counter-rotating rings, and are much more accurate. The advantage of an INS is that it requires no external transmission to determine location.
Interdiction Use of airpower to disrupt or prevent the movement of enemy military units and supplies by attacking transportation routes, vehicles, and bridges deep in the enemy’s rear.
IOC Initial Operational Capability. The point in the life cycle of a weapon system when it officially enters se
rvice and is considered ready for combat, with all training, spare parts, technical manuals, and software complete. The more complex the system, the greater the chance that the originally scheduled IOC will slip.
IRBM Intermediate Range Ballistic Missile. A rocket (typically two-stage) designed to deliver a warhead over regional rather than intercontinental distances. This class of weapons was eliminated by treaty and obsolescence from U.S. and Russian strategic forces, but is rapidly proliferating in various world trouble spots, despite international efforts to limit the export of ballistic missile technologies.
J-3 Operations officer on a joint staff, responsible for assisting the commander in the planning and execution of military operations.
JCS Joint Chiefs of Staff. The senior U.S. military command level, responsible for advising the President on matters of national defense. The JCS consists of a Chairman, who may be drawn from any service, the Chief of Naval Operations, the Chief of Staff of the Army, the Commandant of the Marine Corps, and the Chief of Staff of the Air Force.
JDAM Joint Direct Attack Munition. A general-purpose Mk 83 or Mk 84 bomb or BLU-109 cluster bomb with an inertial guidance package and miniature GPS receiver in a modified tail cone. Initial operational capability originally planned for 1997. Intended for use on Air Force and Navy strike aircraft.
JFACC Joint Forces Air Component Commander. The officer who has operational control over all air units and air assets assigned to a theater of operations. The JFACC is typically drawn from the service that has the greatest amount of airpower in the area of operations, and reports directly to the theater commander in chief.
Jink A violent zigzag maneuver intended to confuse enemy tracking or fire-control systems.
Joy Stick The control stick of a fixed-wing aircraft. Moving the stick forward or back makes the nose pitch up or down. Moving the stick left or right makes the aircraft bank in the corresponding direction. The rudder is separately controlled by foot pedals.
JP-5 Standard U.S. Air Force jet fuel. A petroleum distillate similar to kerosene.
