An IATA airport code , also known as an IATA location identifier , IATA station code , or simply a location identifier , is a three-letter geocode designating many airports and metropolitan areas around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.
83-397: Holloman Air Force Base ( IATA : HMN , ICAO : KHMN , FAA LID : HMN ) is a United States Air Force base established in 1942 located six miles (10 km) southwest of the central business district of Alamogordo , which is the county seat of Otero County , New Mexico , United States. The base was named in honor of Col. George V. Holloman , a pioneer in guided missile research. It
166-593: A comprehensive and controlled series of studies into the effects of deceleration on the human body. This led to fundamental concepts that could be applied to better safeguard aircraft occupants during a crash. The initial phase of the program, as set up by the Aero Medical Laboratory of the Wright Air Development Center , was to develop equipment and instrumentation. This was so aircraft crashes might be simulated, and to study
249-595: A conventional strike force in Europe, the 366th Tactical Fighter Wing moved to Holloman. The move was a result of French president Charles DeGaulle 's deep suspicion of "supranational organizations" and his country's shift away from the NATO orbit in the early 1960s that ultimately led to the closure of American air bases in France . 366th TFW was organized as follows: At the time of the wing's arrival at Holloman, they flew

F-15 Eagle era On 20 December 1977, the wing began converting from the F-4D to F-15A/Bs. The transition was completed on 4 June 1978. History was made during February 1980, when two pilots from the 49th each flew their F-15s 6,200 miles in just over 14 hours, establishing a record for
415-441: A human can withstand at least 46.2 g (in the forward position, with adequate harnessing). This is the highest known acceleration voluntarily encountered by a human, set on December 10, 1954. Stapp reached a speed of 632 mph (1,017 km/h), which broke the land speed record and made him the fastest man on Earth. Stapp believed that the tolerance of humans to acceleration had not yet been reached in tests. He believed it
498-535: A major role, dropping the first bombs against an Iraqi leadership target in Baghdad on 19 March 2003. In all, F-117 pilots flew more than 80 missions and dropped nearly 100 enhanced guided bomb units against key targets. Approximately 300 people deployed with the air package and provided direct support to the F-117 mission. Additionally, hundreds of other 49th FW personnel were deployed on other missions. The 479th TTW
581-567: A new airport is built, replacing the old one, leaving the city's new "major" airport (or the only remaining airport) code to no longer correspond with the city's name. The original airport in Nashville, Tennessee, was built in 1936 as part of the Works Progress Administration and called Berry Field with the designation, BNA. A new facility known as Nashville International Airport was built in 1987 but still uses BNA. This

His first assignment included a series of flights testing various oxygen systems in unpressurized aircraft at 40,000 ft (12.2 km). One of the major problems with high-altitude flight was the danger of "the bends" or decompression sickness . Stapp's work resolved that problem as well as many others, which allowed
747-539: A result, many Military Air Transport Service (MATS) aircraft in USAF and carrier on-board delivery aircraft in USN were equipped or retrofitted with this type of seat. Commercial airlines were made aware of these findings, but still use forward-facing seats. The British Royal Air Force also installed it on many of their military transport aircraft. As a result of Stapp's findings, the acceleration requirement for fighter seats
830-494: A suborbital flight launched 31 January 1961, the first great ape in space, and Enos on a 1961 orbital flight as the third great ape to orbit Earth. The 366th Tactical Fighter Wing arrived on 15 July 1963, making Holloman a Tactical Air Command (TAC) operating base. On 8 April 1966, the 4758th Defense Systems Evaluation Squadron (DSES) arrived from Biggs AFB Texas . The squadron evaluated aircraft weapons systems and to provide training for air defense units. Aircraft flown by

During this deployment the 49th flew more than 21,000 combat hours over just about every battle zone from An Loc to vital installations in the Hanoi vicinity. During five months of combat, the wing did not lose any aircraft or personnel. The unit received an Air Force Outstanding Unit Award with Combat "V" Device for its participation. The 49th TFW officially closed out its Southeast Asia duty on 9 October 1972, turning over Takhli to

Canada's unusual codes—which bear little to no similarity with any conventional abbreviation to the city's name—such as YUL in Montréal , and YYZ in Toronto , originated from the two-letter codes used to identify weather reporting stations in the 1930s. The letters preceding the two-letter code follow
1079-617: Is available. However, many railway administrations have their own list of codes for their stations, such as the list of Amtrak station codes . Airport codes arose out of the convenience that the practice brought pilots for location identification in the 1930s. Initially, pilots in the United States used the two-letter code from the National Weather Service (NWS) for identifying cities. This system became unmanageable for cities and towns without an NWS identifier, and
1162-523: Is different from the name in English, yet the airport code represents only the English name. Examples include: Due to scarcity of codes, some airports are given codes with letters not found in their names: The use of 'X' as a filler letter is a practice to create three-letter identifiers when more straightforward options were unavailable: Some airports in the United States retained their NWS ( National Weather Service ) codes and simply appended an X at
1245-513: Is in conjunction to rules aimed to avoid confusion that seem to apply in the United States, which state that "the first and second letters or second and third letters of an identifier may not be duplicated with less than 200 nautical miles separation." Thus, Washington, D.C. area's three airports all have radically different codes: IAD for Washington–Dulles , DCA for Washington–Reagan (District of Columbia Airport), and BWI for Baltimore (Baltimore–Washington International, formerly BAL). Since HOU

He said "I felt a sensation in the eyes, somewhat like the extraction of a molar without anesthetic," but his survival without any permanent injuries supported the development of further safety technologies including the ejection seat . Also developed by Stapp as an added safety measure was an improved version of the currently used shoulder strap and lap belt . The new high-strength harness withstood 45.4 g (445 m/s²), compared to
1411-543: Is not followed outside the United States: In addition, since three letter codes starting with Q are widely used in radio communication, cities whose name begins with "Q" also had to find alternate codes, as in the case of: IATA codes should not be confused with the FAA identifiers of U.S. airports. Most FAA identifiers agree with the corresponding IATA codes, but some do not, such as Saipan , whose FAA identifier

Stapp also participated in wind-blast experiments, in which he flew in jet aircraft at high speeds to determine whether or not it was safe for a pilot to remain with his aircraft if the canopy should accidentally blow off. Stapp stayed with his aircraft at a speed of 570 mph (920 km/h) with the canopy removed, and suffered no injurious effects from

In 1993 these squadrons were inactivated with assets transferred to the 7th, 8th and 9th Fighter Squadrons. The 7th was designated a combat training squadron, the 8th and 9th being deployable operational fighter squadrons. On 1 July 1993, the 20th Fighter Squadron was activated as part of the 49th Operations Group, taking over
2822-501: The 49th underwent a number of transitions. On 1 October 1991, the 49th was redesignated the 49th Fighter Wing as part of an Air Force wide redesignation of units. On 1 November 1991, the 7th Fighter Squadron ceased F-15 operations, performing a Lead-In Fighter Training (LIFT) mission with Northrop AT-38B Talons , preparing for the transition to the Lockheed F-117A Nighthawk . during most of 1992. On 1 June 1992

The intention of the program was for the QF-106 to survive repeated engagements with air-to-air missiles , to make it possible for each QF-106 to last as long as possible before it was destroyed. The last shootdown of a QF-106 (57–2524) took place at Holloman AFB on 20 February 1997. The QF-106

3486-480: The U.S. For example, several airports in Alaska have scheduled commercial service, such as Stebbins and Nanwalek , which use FAA codes instead of ICAO codes. Thus, neither system completely includes all airports with scheduled service. Some airports are identified in colloquial speech by their IATA code. Examples include LAX and JFK .

The QF-106s began operating as a Full-Scale Aerial Target (FSAT) in late 1991 at White Sands Missile Range New Mexico, and later at the Eglin Gulf Test Range in Florida (based at Holloman and Tyndall). A typical mission would employ
3652-481: The United States, because "Y" was seldom used in the United States, Canada simply used the weather station codes for its airports, changing the "Y" to a "Z" if it conflicted with an airport code already in use. The result is that most major Canadian airport codes start with "Y" followed by two letters in the city's name (for example, YOW for O tta w a , YWG for W innipe g , YYC for C algar y , or YVR for V ancouve r ), whereas other Canadian airports append

For instance: Or using a code for the city in one of the major airports and then assigning another code to another airport: When different cities with the same name each have an airport, they need to be assigned different codes. Examples include: Sometimes,

In rare cases, the code comes from the airport's unofficial name, such as Kahului Airport 's OGG (for local aviation pioneer Jimmy H ogg ). In large metropolitan areas, airport codes are often named after
3901-502: The base was planned to "be manned by a skeleton crew merely as a plane refuelling station, [for] emergency landings, etc.", and it was temporarily inactivated on 28 February 1946. Post-war the AAF was used to support the Alamogordo Guided Missile Test Base which had its first Boeing Ground-to-Air Pilotless Aircraft launch on 14 November 1947. With the September 1947 formation of the USAF, in late 1947
3984-502: The code SHA, while the newer Shanghai–Pudong adopted PVG. The opposite was true for Berlin : the airport Berlin–Tegel used the code TXL, while its smaller counterpart Berlin–Schönefeld used SXF; the Berlin Brandenburg Airport has the airport code BER, which is also part of its branding. The airports of Hamburg (HAM) and Hannover (HAJ) are less than 100 nautical miles (190 km) apart and therefore share
4067-420: The decelerator had profound implications for both civilian and military aviation. For instance, the backward-facing seat concept, which was known before, was given great impetus by the crash research program. It proved beyond a doubt that this position was the safest for aircraft passengers and required little harness support, and that a human can withstand much greater deceleration than in the forward position. As
4150-934: The end. Examples include: A lot of minor airfields without scheduled passenger traffic have ICAO codes but not IATA codes, since the four letter codes allow more number of codes, and IATA codes are mainly used for passenger services such as tickets, and ICAO codes by pilots. In the US, such airfields use FAA codes instead of ICAO. There are airports with scheduled service for which there are ICAO codes but not IATA codes, such as Nkhotakota Airport/Tangole Airport in Malawi or Chōfu Airport in Tokyo, Japan. There are also several minor airports in Russia (e.g., Omsukchan Airport ) which lack IATA codes and instead use internal Russian codes for booking. Flights to these airports cannot be booked through
4233-548: The first dual-based tactical fighter wing. The 6583d Air Base Group was inactivated in place. Under the dual-basing concept, the 49th, stationed at Holloman, deployed individual squadrons periodically to Europe , fulfilling their NATO commitment. The operational squadrons of the 49th TFW upon its arrival were: All three squadrons flew the McDonnell Douglas F-4D Phantom II . In 1972 squadron aircraft tail codes were standardized on "HO".

The first run on the rocket sled took place on 30 April 1947 with ballast. The sled ran off the tracks. The first human run took place the following December. Instrumentation on all the early runs was in the developmental stage, and it was not until August 1948 that it
5644-400: The subjects in the backward position, and 55 in the forward position. Stapp, one of the most frequent volunteers on the runs, sustained a fracture of his right wrist during the runs on two separate occasions, also broke ribs, lost fillings from his teeth and developed bleeding into his retinas that caused temporary vision loss; in one run he survived forces up to 38 g. Stapp's research on
5727-401: The two-letter code of the radio beacons that were the closest to the actual airport, such as YQX in Gander or YXS in Prince George . Four of the ten provincial capital airports in Canada have ended up with codes beginning with YY, including: Canada's largest airport is YYZ for Toronto Pearson (as YTZ was already allocated to Billy Bishop Toronto City Airport , the airport was given
5810-529: The use of two letters allowed only a few hundred combinations; a three-letter system of airport codes was implemented. This system allowed for 17,576 permutations, assuming all letters can be used in conjunction with each other. Since the U.S. Navy reserved "N" codes, and to prevent confusion with Federal Communications Commission broadcast call signs , which begin with "W" or "K", the airports of certain U.S. cities whose name begins with one of these letters had to adopt "irregular" airport codes: This practice
5893-416: The wind blasts. Among these experiments was one of the first high-altitude skydives, executed by Stapp himself. He also supervised research programs in the field of human factors in escape from aircraft. Stapp was an inveterate collector of aphorisms and adages, kept a logbook of such, and the practice spread to his entire working group. He published a collection of these in 1992. Stapp is credited with being
5976-415: The wing participated in its first dual-basing exercise, Crested Cap I, deploying 2,000 personnel and 72 aircraft to NATO bases in Europe. Also in 1969, the 49th earned the coveted MacKay Trophy for the "most meritorious flight of the year", for the redeployment from Germany to Holloman after Crested Cap II. The MacKay Trophy recognized the 49th for the fastest non-stop deployment of jet aircraft accomplished by
6059-425: Was activated at Holloman on 1 January 1977 to provide Lead-In Fighter Training (LIFT) training for pilots assigned to fly tactical fighter or attack aircraft. The 479th Flew AT-38B Talons with the following squadrons: All 479th TTW aircraft carried the "HM" tail code. The LIFT program was sharply cut back in 1991, and the wing replaced by the 479th Fighter Group at Holloman, with the aircraft being consolidated under
6142-443: Was activated on 20 September 1949 to oversee all research and development projects. The Holloman Air Development Center became the base operating unit on 10 October 1952, and the 3,500 ft (1,100 m) rocket-powered sled was first run on 19 March 1954. On 10 December 1954, Lt Colonel (Dr.) John P. Stapp rode a Holloman rocket propelled test sled, Sonic Wind No. 1, to a speed of 632 miles per hour (1,017 km/h). The center
6225-474: Was adequate to begin recording. By August 1948, sixteen human runs had completed, all in the backward-facing position. Forward-facing runs started in August 1949. Most of the earlier tests ran to compare the standard Air Force harnesses with a series of modified harnesses. This was to determine which type gave the best protection to the pilot. By June 8, 1951, 74 human runs had been made on the decelerator, 19 with
6308-462: Was an American career U.S. Air Force officer, flight surgeon , physician , biophysicist , and pioneer in studying the effects of acceleration forces on humans. He was a colleague and contemporary of Chuck Yeager , and became known as "the fastest man on earth". His work on Project Manhigh pioneered many developments for the US space program. Born in Salvador de Bahia , Brazil , Stapp
6391-515: Was awarded to Flight Systems Inc. (later Honeywell) to modify 194 surplus Convair F-106 Delta Dart aircraft stored at Davis-Monthan AFB Arizona to the QF-106A target drone configuration. This program came to be known as Pacer Six, and the first flight of a converted drone took place in July 1987. Following the completion of an initial batch of ten QF-106s in 1990, most of the work was transferred to
6474-493: Was delivered by Col. Kevin Zeeck on 18 November. The second, 72-1218, arrived at the base two days later. The remaining 14 F-4s arrived at AMARG by the second week of January 2005 in 4 further waves. The 48th Rescue Squadron was activated at Holloman AFB on 1 May 1993 with its six Sikorsky HH-60G Pave Hawk helicopters. The personnel of the 48th deployed six times in support of Operations Northern and Southern Watch. Additionally,
6557-414: Was increased considerably up to 32 g (310 m/s²). His work showed that a pilot could walk away from crashes when properly protected by harnesses if the seat does not break loose. The "side saddle" or sideways-facing harness was also developed by Stapp. The new triangular-shaped harness gave vastly increased protection to fully equipped paratroopers. It was made of nylon mesh webbing, fit snugly over
6640-655: Was inducted into the National Aviation Hall of Fame for his work in aviation safety. In 1991, Stapp was awarded the National Medal of Technology , "for his research on the effects of mechanical force on living tissues leading to safety developments in crash protection technology". In 2012, 13 years after his death, Stapp was awarded the Air Force Space and Missile Pioneers award. The award recognizes individuals for their significant role in
6723-750: Was renamed the Air Force Missile Development Center on 1 September 1957 and inactivated on 1 August 1970. Additionally, Captain Joseph W. Kittinger, Jr. , stepped out of an open balloon gondola at 102,800 feet (31.3 km) on 16 August 1960, in an attempt to evaluate techniques of high altitude bailout. Capt Kittinger's jump lasted 13 minutes, reaching a velocity of 614 mph (988 km/h). That jump broke four world records: highest open gondola manned balloon flight, highest balloon flight of any kind, highest bailout, and longest free fall. The Aero-Medical Field Laboratory at Holloman "conducted space flight training with chimpanzees [in] 1961–1962", including Ham on
6806-686: Was replaced by the QF-4 Phantom drone. Today, the 96th Test Group from Eglin Air Force Base Florida is responsible for operational testing and evaluation of new equipment and systems proposed for use by these forces. Current initiatives include advanced self-protection systems for combat aircraft, aircrew life support systems, aerial reconnaissance improvements, new armament and weapons delivery systems, and improved maintenance equipment and logistics support. On 15 July 1963, after serving at Chaumont-Semoutiers Air Base , France as
6889-755: Was the eldest of four sons of Reverend Charles Franklin Stapp and Mrs. Mary Louise Shannon, Baptist missionaries. He studied in Texas at Brownwood High School in Brownwood and San Marcos Baptist Academy in San Marcos . In 1931, Stapp received a bachelor's degree from Baylor University in Waco , an MA from Baylor in 1932, a PhD in Biophysics from the University of Texas at Austin in 1940, and an MD from
