124-538: Jomo Kenyatta International Airport ( IATA : NBO , ICAO : HKJK ) is an international airport serving Nairobi , the capital and largest city of Kenya . The other three important international airports in Kenya include Kisumu International Airport , Moi International Airport and Eldoret International Airport . Located in the Embakasi suburb 18 kilometres (11 mi) southeast of Nairobi's central business district,

248-535: A 3,200 nmi (5,900 km; 3,700 mi) range. A total of 154 Boeing 720s and 720Bs were built until 1967. Some 720s were later converted to the 720B specification. The 720 was succeeded by the Boeing 727 trijet. The 707-120 was the first production 707 variant, with a longer, wider fuselage, and greater wingspan than the Dash 80. The cabin had a full set of rectangular windows and could seat up to 189 passengers. It

372-406: A Dutch roll incident he experienced as a passenger on an early commercial 707 flight. As the aircraft's movements did not cease and most of the passengers became ill, he suspected a misrigging of the directional autopilot (yaw damper). He went to the cockpit and found the crew unable to understand and resolve the situation. He introduced himself and relieved the ashen-faced captain who immediately left

496-414: A convertible passenger–freight configuration, which became the most widely produced variant of the 707. The 707-320C added a strengthened floor and a new cargo door to the -320B model. The wing was fitted with three-section leading-edge flaps which allowed the removal of the underfin. A total of 335 of this variant were built, including some with JT3D-7 engines (19,000 lbf (85 kN) takeoff thrust) and

620-454: A demonstration flight over Lake Washington outside Seattle , on August 7, 1955, test pilot Tex Johnston performed a barrel roll in the 367-80 prototype. Although he justified his unauthorized action to Bill Allen , then president of Boeing, as selling the airplane with a 1 'g' maneuver he was told not to do it again. The 132 in (3,400 mm) wide fuselage of the Dash 80 was large enough for four-abreast (two-plus-two) seating like

744-412: A dominant airliner manufacturer with its 7x7 series . The initial, 145-foot-long (44 m) 707-120 was powered by Pratt & Whitney JT3C turbojet engines. The shortened, long-range 707-138 and the more powerful 707-220 entered service in 1959. The longer-range, heavier 707-300/400 series has larger wings and is stretched slightly by 8 feet (2.4 m). Powered by Pratt & Whitney JT4A turbojets,

868-484: A fuselage 55 feet (17 m) longer than the 707-320B, to 208.6 feet (63.6 m) in length. This second model would have carried 225 passengers in mixed-class configuration and 279 passengers in all-economy configuration. Like the 707-620, the 707-820 was also set to compete with the stretched DC-8-60 Super Series models. The design was being pitched to American, TWA, BOAC, and Pan Am at the time of its proposal in early 1965. The 707-820 would have cost US$ 10,000,000. Like

992-664: A joint venture with Seven Q Seven (SQS) and Omega Air, selected the JT8D-219 low-bypass turbofan as a replacement powerplant for Boeing 707-based aircraft, calling their modified configuration a 707RE. Northrop Grumman selected the -219 to re-engine the US Air Force's fleet of 19 E-8 Joint STARS aircraft, which would allow the J-STARS more time on station due to the engine's greater fuel efficiency. NATO also planned to re-engine their fleet of E-3 Sentry AWACS aircraft. The -219

1116-467: A kink in the trailing edge to add area inboard. Takeoff weight was increased to 302,000 lb (137,000 kg) initially and to 312,000 lb (142,000 kg) with the higher-rated JT4As and center section tanks. Its first flight was on January 11, 1958; 69 turbojet 707-320s were delivered through January 1963, the first passengers being carried (by Pan Am) in August 1959. The 707-420 was identical to

1240-436: A longer fuselage and wing meant a painstaking redesign of the wing and landing-gear structures. Rather than spend money on upgrading the 707, engineer Joe Sutter stated the company "decided spending money on the 707 wasn't worth it". The project was cancelled in 1966 in favor of the newer Boeing 747. The 707-820 was a proposed intercontinental stretched variant of the 707-320B. This 412,000-pound MTOW (187,000 kg) variant

1364-566: A misnomer when Embakasi itself is 1,624 metres (5,328 ft) AMSL ), 40 km (25 mi) away, and 10 degrees off the runway centre-line. Visibility rarely falls below this obstruction-distance in the clear air of the plains, and it may have been possible to see the summit of Mount Meru in Northern Tanzania, about 220 km (140 mi) away; both Kilimanjaro 213 km (132 mi) away and Mount Kenya could be clearly seen. On Sunday 9 March 1958, Embakasi Airport (now JKIA)

1488-567: 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

1612-879: A rail link to central Nairobi went into operation. [REDACTED] Media related to Jomo Kenyatta International Airport at Wikimedia Commons IATA airport code The assignment of these codes is governed by IATA Resolution 763, and it is administered by the IATA's headquarters in Montreal , Canada. The codes are published semi-annually in the IATA Airline Coding Directory. IATA provides codes for airport handling entities, and for certain railway stations. Alphabetical lists of airports sorted by IATA code are available. A list of railway station codes , shared in agreements between airlines and rail lines such as Amtrak , SNCF , and Deutsche Bahn ,

1736-666: A stronger structure to support a maximum takeoff weight increased by 19,000 lb (8,600 kg), along with modifications to the wing. The 707-320B series enabled nonstop westbound flights from Europe to the West Coast of the United States and from the US to Japan. The final 707 variant was the 707-320C, (C for "Convertible"), which had a large fuselage door for cargo. It had a revised wing with three-sectioned leading-edge flaps, improving takeoff and landing performance and allowing

1860-596: A takeoff weight of 335,000 lb (152,000 kg). Most -320Cs were delivered as passenger aircraft with airlines hoping the cargo door would increase second-hand values. The addition of two additional emergency exits, one on either side aft of the wing raised the maximum passenger limit to 219. Only a few aircraft were delivered as pure freighters. One of the final orders was by the Iranian Government for 14 707-3J9C aircraft capable of VIP transportation, communication, and in-flight refueling tasks. The 707-700

1984-596: A threat to the 757 and 767 programs. The information gathered from testing led to the eventual retrofitting of CFM56 engines to the USAF C-135/KC-135R models, and some military versions of the 707 also used the CFM56. The Douglas DC-8 "Super 70" series with CFM56 engines was developed and extended the DC-8's life in a stricter noise regulatory environment. As a result, significantly more DC-8s remained in service into

2108-460: A viable option because the installation of larger, more powerful engines would need a larger undercarriage, which was not feasible given the design's limited ground clearance at takeoff. Boeing's answer to the problem was the first wide-body airliner—the Boeing 747 . The 707's first-generation engine technology was also rapidly becoming obsolete in the areas of noise and fuel economy, especially after

2232-526: A year. The only rival in intercontinental jet aircraft production at the time was the British de Havilland Comet. However, the Comet series had been the subject of fatal accidents (due to design flaws) early in its introduction and withdrawn from service; virtually redesigned from scratch, it was still smaller and slower than the 707 when reintroduced as version -4. In addition, airlines and their passengers at

2356-528: Is 00501. Discussions about building the airport date back to 1945. At that time, the colonial power—Britain—and its national airline, BOAC , were worried that the existing airport at Eastleigh was inadequate for post-War civilian airliners. The costs of improving Eastleigh versus developing a new airport occupied planners for eight years. Who would pay was a major issue. Plans for the airport were drawn up in 1953, work started in January 1954, and by mid-1957 it

2480-510: Is 60 metres (200 ft) wide and 4.2 kilometres (2.6 mi) long. This is an ICAO code F which can handle the new generation wide bodied aircraft like the Airbus A380 and the Boeing 747-8 . The new runway was designed with fog lights, whereas the current runway is only lit at the sides. The runway would also have enabled long haul flights to destinations like New York city carrying up to 32 tonnes of passengers and cargo. In 2019, however,

2604-509: Is GSN and its IATA code is SPN, and some coincide with IATA codes of non-U.S. airports. 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

2728-526: Is also a Turkish Airlines TAV Lounge (T1B), as well as the Swissport Aspire Lounge (T1C). Both are regular lounges, which can be accessed by elite status or a paid-pass. In January 2017, a new instrument landing system -equipped runway 5,500 metres (18,000 ft) in length was approved for construction at a cost of KES 37 billion shillings (approximately US$ 370 million). According to KAA's managing director John Anderson, construction of

2852-554: 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

2976-523: 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

3100-513: 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

3224-543: 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

3348-568: Is publicized as being half the cost of the competing powerplant, the CFM International CFM56 , and is 40 dB quieter than the original JT3D engines. The first commercial orders for the 707 came on October 13, 1955, when leading global carrier Pan Am committed to 20 Boeing 707s, and 25 Douglas DC-8s, dramatically increasing their passenger capacity (in available revenue passenger seat-miles per hour/per day) over its existing fleet of propeller aircraft. The competition between

3472-416: Is used for William P. Hobby Airport , the new Houston–Intercontinental became IAH. The code BKK was originally assigned to Bangkok–Don Mueang and was later transferred to Suvarnabhumi Airport , while the former adopted DMK. The code ISK was originally assigned to Gandhinagar Airport (Nashik's old airport) and later on transferred to Ozar Airport (Nashik's current airport). Shanghai–Hongqiao retained

3596-489: Is used primarily by Skyteam member airlines. Terminal 1B houses common-use check-in counters, with security check points leading to the departure lounge on level 1. On level one is the Aspire lounge as well as duty-free shopping outlets and cafes. This terminal houses common-use check-in counters, with security checkpoints leading to the departure lounge on level 1. On level 1 are duty-free shops, Kenya Airways Simba Lounge and

3720-484: The 1973 oil crisis . Operations of the 707 were threatened by the enactment of international noise regulations in 1985. Shannon Engineering of Seattle developed a hush kit with funding from Tracor, Inc , of Austin, Texas. By the late 1980s, 172 Boeing 707s had been equipped with the Quiet 707 package. Boeing acknowledged that more 707s were in service than before the hush kit was available. Trans World Airlines flew

3844-456: The 377 Stratocruiser , quickly faded with only 56 examples sold and no new orders as the 1940s drew to a close. That venture had netted the company a $ 15 million loss. During 1949 and 1950, Boeing embarked on studies for a new jet transport and saw advantages with a design aimed at both military and civilian markets. Aerial refueling was becoming a standard technique for military aircraft, with over 800 KC-97 Stratofreighters on order. The KC-97

3968-571: The Canadian transcontinental railroads were built, each station was assigned its own two-letter Morse code : When the Canadian government established airports, it used the existing railway codes for them as well. If the airport had a weather station, authorities added a "Y" to the front of the code, meaning "Yes" to indicate it had a weather station or some other letter to indicate it did not. When international codes were created in cooperation with

4092-409: The first responders choosing to loot the airport instead of fighting the blaze. International arrivals had been bused to a temporary facility set up in the ground floor of the new parkade until the reconstruction of the damaged areas. In June 2015, a new, fully functional temporary terminal building became operational. This terminal building was planned for a design life of 10 years, until completion of

4216-492: The "20" part of the designation is Boeing's "customer number" for its development aircraft. Announced in July 1957 as a derivative for shorter flights from shorter runways, the 707-020 first flew on November 23, 1959. Its type certificate was issued on June 30, 1960, and it entered service with United Airlines on July 5, 1960. As a derivative, the 720 had low development costs, allowing profitability despite few sales. Compared to

4340-404: The -320 by adding a second inboard kink, a dog-toothed leading edge, and curved low-drag wingtips instead of the earlier blunt ones. These wingtips increased overall wingspan by 3.0 ft (0.9 m). Takeoff gross weight was increased to 328,000 lb (149,000 kg). The 175 707-320B aircraft were all new-build; no original -320 models were converted to fan engines in civilian use. First service

4464-409: The -320, but fitted with Rolls-Royce Conway 508 (RCo.12) turbofans (or by-pass turbojets as Rolls-Royce called them) of 18,000 lbf (80 kN) thrust each. The first announced customer was Lufthansa . BOAC 's controversial order was announced six months later, but the British carrier got the first service-ready aircraft off the production line. The British Air Registration Board refused to give

4588-568: The -320, but with Conway turbofan engines. Though initially fitted with turbojet engines, the dominant engine for the Boeing 707 family was the Pratt & Whitney JT3D , a turbofan variant of the JT3C with lower fuel consumption and higher thrust. JT3D-engined 707s and 720s were denoted with a "B" suffix. While many 707-120Bs and -720Bs were conversions of existing JT3C-powered machines, 707-320Bs were available only as newly built aircraft, as they had

4712-432: The 21st century than 707s. The 707-620 was a proposed domestic range-stretched variant of the 707-320B. The 707-620 was to carry around 200 passengers while retaining several aspects of the 707-320B. It would have been delivered around 1968 and would have also been Boeing's answer to the stretched Douglas DC-8 Series 60 . Had the 707-620 been built, it would have cost around US$ 8,000,000. However, engineers discovered that

4836-399: The 707 also led to the upgrading of air traffic control systems to prevent interference with military jet operations. As the 1960s drew to a close, the exponential growth in air travel led to the 707 being a victim of its own success. The 707 had become too small to handle the increased numbers of passengers on the routes for which it had been designed. Stretching the fuselage again was not

4960-461: The 707 and DC-8 was fierce. Pan Am ordered these planes when and as they did so that they would be the operators of the "first-off" production line for each aircraft type. Once the initial batch of the aircraft had been delivered to them and put into operation, Pan Am would have the distinction of being not only the "Launch Customer" for both transcontinental American jets, but the exclusive operator of American intercontinental jet transports for at least

5084-425: The 707's width again to compete, this time to 148 in (3,760 mm). The first flight of the first-production 707-120 took place on December 20, 1957, and FAA certification followed on September 18, 1958. Both test pilots Joseph John "Tym" Tymczyszyn and James R. Gannett were awarded the first Iven C. Kincheloe Award for the test flights that led to certification. A number of changes were incorporated into

5208-505: The 707-120, it has a length reduced by 9 feet (2.7 m), a modified wing and a lightened airframe for a lower maximum takeoff weight . Powered by four Pratt & Whitney JT3C turbojets, the initial 720 could cover a 2,800 nmi (5,200 km; 3,200 mi) range with 131 passengers in two classes. Powered by JT3D turbofans, the 720B first flew on October 6, 1960, and entered service in March 1961. It could seat 156 passengers in one class over

5332-472: The 707-320 entered service in 1959, and the 707-420 with Rolls-Royce Conway turbofans in 1960. The 720, a lighter short-range variant, was also introduced in 1960. Powered by Pratt & Whitney JT3D turbofans, the 707-120B debuted in 1961 and the 707-320B in 1962. The 707-120B typically flew 137 passengers in two classes over 3,600 nautical miles [nmi] (6,700 km; 4,100 mi), and could accommodate 174 in one class. With 141 passengers in two classes,

5456-663: The 707-320/420 could fly 3,750 nmi (6,940 km; 4,320 mi) and the 707-320B up to 5,000 nmi (9,300 km; 5,800 mi). The 707-320C convertible passenger-freighter model entered service in 1963, and passenger 707s have been converted to freighter configurations. Military derivatives include the E-3 Sentry airborne reconnaissance aircraft and the C-137 Stratoliner VIP transport. In total, 865 Boeing 707s were produced and delivered, not including 154 Boeing 720s. During and after World War II, Boeing

5580-511: The B-47 and B-52, and had developed the yaw damper system on the B-47 that would be applied to later swept-wing configurations like the 707. However, many pilots new to the 707 had no experience with this instability as they were mostly accustomed to flying straight-wing propeller-driven aircraft such as the Douglas DC-7 and Lockheed Constellation . On one customer-acceptance flight, where

5704-580: The Boeing 707. After suspending its scheduled passenger service in April 2013, Saha continued to operate a small fleet of 707s on behalf of the Iranian Air Force . As of 2019, only a handful of 707s remain in operation, acting as military aircraft for aerial refueling, transport, and AWACS missions. Although certified as Series 100s, 200s, 300s, etc., the different 707 variants are more commonly known as Series 120s, 220s, 320s, and so on, where

5828-460: The DC-8, such as United , Delta , and Eastern , were left without jets until September and lost market share on transcontinental flights. Qantas was the first non-US airline to use the 707s, starting in 1959. The 707 quickly became the most popular jetliner of its time. Its success led to rapid developments in airport terminals, runways, airline catering, baggage handling, reservations systems, and other air transport infrastructure. The advent of

5952-587: The KES 56 billion (US$ 560 million) Greenfield Terminal Project was terminated by Kenya Airports Authority because the contractor failed to secure funds, thus ending Kenya's vision of having the largest terminal in Africa. In February 2017, the airport was awarded a Category One Status by the Federal Aviation Administration of the United States, thus allowing possible direct flights between

6076-519: The Mara Lounge and Mount Kenya Lounge, both at airside, Level 1, and open 24 hours. Terminal 3, also referred to as the "Greenfield Terminal", is a projected new terminal building with a capacity of 20 million passengers per year. Construction first began in 2014, but was cancelled in 2016. With passenger numbers at the airport nearing the capacity limit, Roads, Transport, and Public Works Cabinet Secretary Kipchumba Murkomen announced in 2023 that

6200-596: The President William Ruto 's government would resume the project in 2024 as a public-private partnership (PPP) with an expected completion in 2027. In January 2015, the Simba Lounge and Pride Lounge on the second floor of Terminal 1A were opened. The two facilities, with a combined capacity of 350 people, were developed at a cost of KES 135 million ($ 1.35 million), and are for the use of KQ's Premier World and SkyTeam's Sky Priority passengers. There

6324-553: The Stratocruiser. Answering customers' demands and under Douglas competition, Boeing soon realized this would not provide a viable payload, so it widened the fuselage to 144 in (3,660 mm) to allow five-abreast seating and use of the KC-135's tooling. Douglas Aircraft had launched its DC-8 with a fuselage width of 147 in (3,730 mm). The airlines liked the extra space and six-abreast seating, so Boeing increased

Following the closure of the main international arrivals and departures terminal after a fire , a parking facility was converted into the temporary international arrivals terminal. This terminal was subsequently opened to serve arriving passengers on airlines operating out of Terminals 1B and 1C. Remodeling and extending Terminals 1B, 1C and 1D

6572-499: 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 .

On 7 August 2013, a fire originating in the immigration area caused massive damage to the airport and forced it to suspend operations temporarily. Unit 3, usually dedicated to domestic operations, was used temporarily for international traffic. The worst fire in

6820-481: 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

6944-423: The aircraft a certificate of airworthiness, citing insufficient yaw control, excessive rudder forces, and the ability to over-rotate on takeoff, stalling the wing on the ground (a fault of the de Havilland Comet 1). Boeing responded by adding 40 in (100 cm) to the vertical stabilizer, applying full instead of partial rudder boost, and fitting an underfin to prevent over-rotation. These modifications except to

The working conditions were so poor that were reports of suicides and self-mutilation among the labourers. The site chosen, on a lava plain 18 kilometres (11 mi) from the centre of Nairobi (the city's two other airports, Eastleigh and Wilson, are closer), has approaches free from any obstruction for at least 18 km (11 mi) in any direction. The nearest mountain ("high ground") would be

Under the vision, JKIA's aging infrastructure was to be upgraded to World Class standards. New terminals and runway upgrades were to be added in phases. The African Development Bank carried out an Environmental Impact Assessment on the development of Phase 1 of

7316-418: The airport has scheduled flights to destinations in over 50 countries. Originally named Embakasi Airport , the airport's name was changed in 1978 to honour Jomo Kenyatta , Kenya's first president and Prime Minister . The airport served over 7 million passengers in 2016, making it the seventh busiest airport in passenger traffic on the continent. The postal code for Jomo Kenyatta International Airport (JKIA)

In large metropolitan areas, airport codes are often named after

7812-480: The airport's history occurred on the fifteenth anniversary of the 1998 United States embassy bombings in Nairobi and Dar es Salaam , but no connection was immediately obvious and no terrorist group has claimed responsibility. The cause is not believed to be intentional, as no explosive devices were discovered during the initial investigation. According to Kenyan officials, firefighting efforts were hampered by some of

The 707-320 Intercontinental is a stretched version of the turbojet-powered 707-120, initially powered by JT4A-3 or JT4A-5 turbojets producing 15,800 lbf (70.3 kN) each (most eventually got 17,500 lbf (77.8 kN) JT4A-11s). The interior allowed up to 189 passengers, the same as the -120 and -220 series, but improved two-class capacity due to an 80-in fuselage stretch ahead of

8060-515: The building; the minimum of signs is required. And although Embakasi was designed to meet Nairobi's particular needs, both airports shared a lightness and spaciousness that was at the time extraordinarily refreshing. The fitting and colour schemes employed at the then Embakasi Airport were first-class. In 1972, the World Bank approved funds for further expansion of the airport, including a new international and domestic passenger terminal building,

8184-416: The cockpit feeling ill. Johnston disconnected the faulty autopilot and manually stabilized the plane "with two slight control movements". Johnston recommended Boeing increase the height of the tail fin , add a boosted rudder as well as add a ventral fin . These modifications were aimed at mitigating Dutch roll by providing more directional stability in yaw . The initial 145-foot-long (44 m) 707-120

8308-502: 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

8432-565: The country. It also had over 7 million passengers pass through it. Domestic travellers through the Jomo Kenyatta International Airport (JKIA) made up 40% cent of overall passengers in 2016. This is an increase from 32% five years prior (2012). Terminal 1A has a capacity of 2.5 million passengers a year and three levels, 30 check-in counters, 12 departure gates, ample seating, and food and retail options. The arrivals area houses five baggage carousels. This terminal

8556-448: The design constraints imposed by limitations of late-1940s jet engines, developing a robust, safe, and high-capacity jet aircraft was within reach for Boeing. Boeing studied numerous wing and engine layouts for its new transport/tanker, some of which were based on the B-47 and C-97, before settling on the 367-80 "Dash 80" quadjet prototype aircraft. Less than two years elapsed from project launch in 1952 to rollout on May 14, 1954, with

8680-886: 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

8804-525: The fin under the tail became standard on all 707 variants and were retrofitted to all earlier 707s. The 37 -420s were delivered to BOAC, Lufthansa, Air-India , El Al , and Varig through November 1963; Lufthansa was the first to carry passengers, in March 1960. The 707-320B had the application of the JT3D turbofan to the Intercontinental, but with aerodynamic refinements. The wing was modified from

8928-429: The first jetliner developed and produced by Boeing Commercial Airplanes . Developed from the Boeing 367-80 prototype first flown in 1954, the initial 707-120 first flew on December 20, 1957. Pan Am began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 is a swept wing quadjet with podded engines . Its larger fuselage cross-section allowed six-abreast economy seating, retained in

9052-487: The first Dash 80 flying on July 15, 1954. The prototype was a proof-of-concept aircraft for both military and civilian use. The United States Air Force was the first customer, using it as the basis for the KC-135 Stratotanker aerial refueling and cargo aircraft. Whether the passenger 707 would be profitable was far from certain. At the time, nearly all of Boeing's revenue came from military contracts. In

9176-557: The first three letters of the city in which it is located, for instance: The code may also be a combination of the letters in its name, such as: Sometimes the airport code reflects pronunciation, rather than spelling, namely: For many reasons, some airport codes do not fit the normal scheme described above. Some airports, for example, cross several municipalities or regions, and therefore, use codes derived from some of their letters, resulting in: Other airports—particularly those serving cities with multiple airports—have codes derived from

9300-478: The following format: Most large airports in Canada have codes that begin with the letter "Y", although not all "Y" codes are Canadian (for example, YUM for Yuma, Arizona , and YNT for Yantai , China), and not all Canadian airports start with the letter "Y" (for example, ZBF for Bathurst, New Brunswick ). Many Canadian airports have a code that starts with W, X or Z, but none of these are major airports. When

9424-597: The form of " YYZ ", a song by the rock band Rush , which utilizes the Morse code signal as a musical motif. Some airports have started using their IATA codes as brand names , such as Calgary International Airport (YYC) and Vancouver International Airport (YVR). Numerous New Zealand airports use codes that contain the letter Z, to distinguish them from similar airport names in other countries. Examples include HLZ for Hamilton , ZQN for Queenstown , and WSZ for Westport . Predominantly, airport codes are named after

9548-484: The government signaled that this project was no longer a priority. The main entrance to Jomo Kenyatta International Airport is on Airport South Road, which can be accessed by an exit from the A109 highway (Mombasa Road). The new 2022 expressway can connect travellers to the airport with no turns or traffic from the city. Passengers can also travel to and from the airport via city Bus Route Number 34. On 7 December 2020,

9672-408: The initial 707's wing to help increase range and payload, giving birth to the 707-320. Pan Am inaugurated 707 service with a christening at National Airport on October 17, 1958, attended by President Eisenhower , followed by a transatlantic flight for VIPs (personal guests of founder Juan Trippe ) from Baltimore's Friendship International Airport to Paris. The aircraft's first commercial flight

9796-487: The international air booking systems or have international luggage transferred there, and thus, they are booked instead through the airline or a domestic booking system. Several heliports in Greenland have 3-letter codes used internally which might be IATA codes for airports in faraway countries. There are several airports with scheduled service that have not been assigned ICAO codes that do have IATA codes, especially in

9920-506: The jets would bear 700-series numbers, and the first would be the 707. The marketing personnel at Boeing chose 707 because they thought it was more appealing than 700. The project was enabled by the Pratt & Whitney JT3C turbojet engine, the civilian version of the J57 that yielded much more power than the previous generation of jet engines and was proving itself with the B-52. Freed from

10044-622: The last new-build 707 airframes built as E-3 and E-6 aircraft. Traces of the 707 are still found in the 737 , which uses a modified version of the 707's fuselage, as well as the same external nose and cockpit configurations as those of the 707. These were also used on the previous 727 , while the 757 also used the 707 fuselage cross-section. The 707's wings are swept back at 35°, and like all swept-wing aircraft, display an undesirable " Dutch roll " flying characteristic that manifests itself as an alternating combined yawing and rolling motion. Boeing already had considerable experience with this on

10168-428: The last scheduled 707 flight for passengers by a US carrier on October 30, 1983, although 707s remained in scheduled service by airlines from other nations for much longer. Middle East Airlines of Lebanon flew 707s and 720s in front-line passenger service until the end of the 1990s. Since LADE of Argentina removed its 707-320Bs from regular service in 2007, Saha Airlines of Iran was the last commercial operator of

10292-484: The later 720 , 727 , 737 , and 757 models. Although it was not the first commercial jetliner in service, the 707 was the first to be widespread, and is often credited with beginning the Jet Age . It dominated passenger air-transport in the 1960s, and remained common through the 1970s, on domestic , transcontinental , and transatlantic flights , as well as cargo and military applications. It established Boeing as

10416-531: The later JT3D-3 version giving 18,000 lbf (80 kN). (This thrust did not require water injection, eliminating both the system and 5000–6000 lb of water.) The -120B had the wing modifications introduced on the 720 and a longer tailplane; a total of 72 were built, 31 for American and 41 for TWA, plus six short-bodied -138Bs for Qantas. American had its 23 surviving -123s converted to -123Bs, but TWA did not convert its 15 -131s. The only other conversions were Pan Am's five surviving -121s and one surviving -139,

10540-462: The launch order for 20 707-121 aircraft by Pan Am and an American Airlines order for 30 707-123 aircraft. The first revenue flight was on October 26, 1958; 56 were built, plus seven short-bodied -138s; the last -120 was delivered to Western in May 1960. The 707-138 was a -120 with a fuselage 10 ft (3.0 m) shorter than the others, with 5 ft (1.5 m) (three frames) removed ahead and behind

10664-404: The maximum takeoff weight the same as that of the -120 (247,000 lb (112 t)), the -138 was able to fly the longer routes that Qantas needed. Braniff International Airways ordered the higher-thrust version with Pratt & Whitney JT4 A engines, the 707-220. The final major derivative was the 707-320, which featured an extended-span wing and JT4A engines, while the 707-420 was the same as

10788-612: The name of the airport itself, for instance: This is also true with some cities with a single airport (even if there is more than one airport in the metropolitan area of said city), such as BDL for Hartford, Connecticut 's B ra dl ey International Airport or Baltimore's BWI, for B altimore/ W ashington I nternational Airport ; however, the latter also serves Washington, D.C. , alongside Dulles International Airport (IAD, for I nternational A irport D ulles) and Ronald Reagan Washington National Airport (DCA, for D istrict of C olumbia A irport). The code also sometimes comes from

10912-466: The new jet service StarStream , launching its first jet service, between New York-Idlewild International Airport and San Francisco International Airport , on January 25, 1959. American Airlines was the first domestic airline to fly its own jets, on January 25, 1959. TWA started domestic 707-131 flights in March and Continental Airlines started 707-124 flights in June; airlines that had ordered only

11036-406: The new runway (which will be bigger than the existing one) was scheduled to begin in 2017. It would have doubled aircraft movement from 25 to 45 per hour. The new runway was designed as a category 2 runway and would have complemented the older runway built in the 1970s. The proposed design of the project was a 4.8 kilometres (3.0 mi) long and 75 metres (250 ft) wide runway. The current runway

11160-416: The one they are located in: Other airport codes are of obscure origin, and each has its own peculiarities: In Asia, codes that do not correspond with their city's names include Niigata 's KIJ , Nanchang 's KHN and Pyongyang 's FNJ . EuroAirport Basel Mulhouse Freiburg , which serves three countries, has three airport codes: BSL, MLH, EAP. Some cities have a name in their respective language which

11284-411: The outer port (number 1) engine mount is distinctly different from the other three, as this engine is not fitted with a turbocompressor. Later-model 707s typically had this configuration, although American Airlines had turbocompressors on engines 2 and 3 only. Early 707 models often had turbocompressor fairings on all four engines, but with only two or three compressors installed. Pratt & Whitney, in

11408-603: The planned new permanent facility. On 11 September 2024, a strike was held by airport workers against proposals to lease the facility to the Adani Group of India for 30 years. The Law Society of Kenya and the Kenya National Commission on Human Rights also criticised the proposal, citing the airport being a "strategic national asset". The two groups also filed petitions in the High Court against

11532-403: The production models from the prototype. A Krueger flap was installed along the leading edge between the inner and outer engines on early 707-120 and -320 models. This was in response to de Havilland Comet overrun accidents which occurred after over-rotating on take-off. Wing stall would also occur on the 707 with over-rotation so the leading-edge flaps were added to prevent stalling even with

11656-421: The project was over US$ 29 million (US$ 111.8 million in 2013 dollars). On 14 March 1978, construction of the current terminal building was completed on the other side of the airport's single runway and opened by President Kenyatta. The airport was again renamed, this time in honour of President Kenyatta after his death about five months later on 22 August 1978. In October 1994, a British Airways Concorde landed at

11780-411: The proposal, which led to it being suspended pending a final decision. There are two terminals. Terminal 1 is arranged in a semi-circular orientation and is divided into four parts: 1A, 1B, 1C, and 1E are used for international arrivals and departures while terminal 1D is used for domestic departures and arrivals. Terminal 2 is used by low-cost carriers. The original terminal, located on the north side of

11904-529: The proposed Green Field Terminal (GFT) which was expected to increase the capacity of JKIA to about 18.5 million passengers annually by the year 2030. The Greenfield Terminal project was to encompass the construction of a four level terminal building comprising a central processing area, a transit hotel, landside retail centers, arrivals and departures plaza. Ancillary facilities which would have included an access road, car parking, access taxiways, Ground Service Equipment (GSE) and bus parking areas. On 29 March 2016,

12028-451: The rainy months was unsuitable for Britannias. The runway was 3,048 metres (10,000 ft) long between thresholds, and was sited roughly 06–24. The 06 approach was used on 90 per cent of the time. A basic strip 3,292 metres (10,801 ft) long and 152 metres (499 ft) wide was prepared for the 46 metres (151 ft) wide runway. There were 8 metres (26 ft) shoulders each side; and consequently 48 metres (157 ft) run-offs beyond

12152-467: The runway, is used by the Kenya Air Force and is sometimes referred to as Old Embakasi Airport . Figures from KAA indicate that the airport's Terminal 1-A has a capacity of 2.5 million passengers The Kenyan government is targeting over 25 million passengers annually by 2025 on the expansion of JKIA's terminals. In 2016, JKIA accounted for more than 70 per cent of overall passenger traffic in

12276-506: The same first and middle letters, indicating that this rule might be followed only in Germany. Many cities retain historical names in their airport codes, even after having undergone an official name/spelling/transliteration change: Some airport codes are based on previous names associated with a present airport, often with a military heritage. These include: Some airports are named for an administrative division or nearby city, rather than

12400-446: The shoulders. After cambering, weak spots were reset, and finally paving machinery was used to lay the asphalt surface. The result was an engineering success of which the contractors were very proud; so accurate was the cambering that the wet surface of the runway dried out evenly on each side of the centre-line. Physically, the great care taken in the engineering resulted in a load classification number of 100 being achieved. The surface at

12524-500: The station code of Malton, Mississauga , where it is located). YUL is used for Montréal–Trudeau (UL was the ID code for the beacon in the city of Kirkland , now the location of Montréal–Trudeau). While these codes make it difficult for the public to associate them with a particular Canadian city, some codes have become popular in usage despite their cryptic nature, particularly at the largest airports. Toronto's code has entered pop culture in

12648-443: The tail dragging on the runway. The initial standard model was the 707-120 with JT3C turbojet engines. Qantas ordered a shorter-bodied version called the 707-138, which was a -120 with six fuselage frames removed, three in front of the wings, and three aft. The frames in the 707 were set 20 in (510 mm) apart, so this resulted in a shortening of 10 ft (3.0 m) to a length of 134 ft 6 in (41.0 m). With

12772-478: The three aircraft delivered to the USAF as -153s and the seven short-bodied Qantas -138s (making 13 total 707s delivered to Qantas between 1959 and 1964). The first flight of the -120B was on June 22, 1960, and American carried the first passengers in March 1961; the last delivery was to American in April 1969. Maximum weight was 258,000 lb (117,000 kg) for both the long- and short-bodied versions. The 707-220

12896-447: The time in 1958, Nairobi was one of the few towns in the world that could boast of a 1965 airport with an expansion option at hand. The number of aircraft movements then was less than 600 per month. The airport architect was strongly influenced by the design of Kloten, Zurich, in the planning and design of Embakasi, although similarities were by no means obvious. Both airports are arranged so that arrival passengers can see completely through

13020-474: The time preferred the more established Douglas Aircraft as a maker of passenger aircraft, and several major carriers committed only to the Douglas DC-8, delayed by Douglas' decision to wait for the larger and more fuel efficient ( Pratt & Whitney JT4A ) turbojet to design a larger and longer range aircraft around. Anticipating this advantage, Boeing made a late and costly decision to redesign and enlarge

13144-418: The time was strong enough to accept the Boeing 707 at maximum gross weight, although 4,572 metres (15,000 ft) rather than 3,048 metres (10,000 ft) length was the probable all-weather length requirement. There was no physical limit to extending the paved length to this figure, but more definite plans for the operation of the big jets into Kenya was required before such an increase was contemplated. At

13268-515: 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

13392-529: 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

13516-402: The ventral fin to be removed (although the taller fin was retained). The 707-320Bs built after 1963 used the same wing as the -320C and were known as 707-320B Advanced aircraft. In total, 1,010 707s were built for civilian use between 1958 and 1978, though many of these found their way to military service. The 707 production line remained open for purpose-built military variants until 1991, with

13640-414: The wing (from 138 ft 10 in (42.32 m) to 145 ft 6 in (44.35 m) ), with extensions to the fin and horizontal stabilizer extending the aircraft's length further. The longer wing carried more fuel, increasing range by 1,600 miles (2,600 km) and allowing the aircraft to operate as true transoceanic aircraft. The wing modifications included outboard and inboard inserts, as well as

13764-772: The wing, giving increased range. Maximum takeoff weight was the same 247,000 lb (112,000 kg) as the standard version. It was a variant for Qantas, thus had its customer number 38. To allow for full-load takeoffs at the midflight refueling stop in Fiji, the wing's leading-edge slats were modified for increased lift, and the allowable temperature range for use of full takeoff power was increased by 10°F (5.5°C). Seven -138s were delivered to Qantas between June and September 1959, and they first carried passengers in July of that year. The 707-120B had Pratt & Whitney JT3D-1 turbofan engines, which were quieter, more powerful, and more fuel-efficient, rated at 17,000 lbf (75.6 kN), with

13888-503: The yaw damper was turned off to familiarize the new pilots with flying techniques, a trainee pilot's actions violently exacerbated the Dutch roll motion and caused three of the four engines to be torn from the wings. The plane, a brand new 707-227, N7071 , destined for Braniff, crash-landed on a river bed north of Seattle at Arlington, Washington , killing four of the eight occupants. In his autobiography, test pilot Tex Johnston describes

14012-484: Was June 1962, with Pan Am. The 707-320B Advanced is an improved version of the -320B, adding the three-section leading-edge flaps already seen on the -320C. These reduced takeoff and landing speeds and altered the lift distribution of the wing, allowing the ventral fin found on earlier 707s to be removed. From 1965, -320Bs had the uprated -320C undercarriage allowing the same 335,000 lb (152,000 kg) MTOW. These were often identified as 707-320BA-H. The 707-320C has

14136-496: Was a test aircraft used to study the feasibility of using CFM International CFM56 engines on a 707 airframe and possibly retrofitting existing aircraft with the engine. After testing in 1979, N707QT , the last commercial 707 airframe, was restored to 707-320C configuration and delivered to the Moroccan Air Force as a tanker aircraft via a "civilian" order. Boeing abandoned the retrofit program, since they felt it would be

14260-457: Was designed for hot and high operations with more powerful 15,800 lbf (70.3 kN) Pratt & Whitney JT4A-3 turbojets. Five of these were produced, but only four were ultimately delivered, with one being lost during a test flight. All were for Braniff International Airways and carried the model number 707-227; the first entered service in December 1959. This version was made obsolete by

14384-466: Was designed for transcontinental routes, and often required a refueling stop when flying across the North Atlantic. It had four Pratt & Whitney JT3C-6 turbojets, civilian versions of the military J57, initially producing 13,000 lbf (57.8 kN) with water injection . Maximum takeoff weight was 247,000 lb (112,000 kg) and first flight was on December 20, 1957. Major orders were

14508-406: Was found possible to bring the operational date forward to mid-March 1958. The task was by no means straightforward, and many problems —largely of a civil engineering nature—had to be overcome before the runway could be built. An extensive amount of the airport's construction was done utilizing forced labour, many of whom were suspected of being Mau Mau members . Due to the enormous pressure to finish

14632-416: Was from Idlewild Airport , New York, to Le Bourget , Paris, on October 26, 1958, with a fuel stop in Gander, Newfoundland . In December, National Airlines operated the first US domestic jet airline flights between New York/Idlewild and Miami, using 707s leased from Pan Am. In February 1956, rival global giant Trans World Airlines' then-President Howard Hughes ordered eight new Boeing 707-120, dubbing

14756-495: Was known for its military aircraft. The company had produced innovative and important bombers, from the B-17 Flying Fortress and B-29 Superfortress to the jet-powered B-47 Stratojet and B-52 Stratofortress , but its commercial aircraft were not as successful as those from Douglas Aircraft and other competitors. As Douglas and Lockheed dominated the postwar air transport boom, the demand for Boeing's offering,

14880-482: Was not ideally suited for operations with the USAF's new fleets of jet-powered fighters and bombers; this was where Boeing's new design would win military orders. As the first of a new generation of American passenger jets, Boeing wanted the aircraft's model number to emphasize the difference from its previous propeller-driven aircraft, which bore 300-series numbers. The 400-, 500- and 600-series were already used by their missiles and other products, so Boeing decided that

15004-592: Was opened by the last colonial governor of Kenya, Sir Evelyn Baring . The airport was due to be opened by Queen Elizabeth The Queen Mother ; however, she was delayed in Australia due to an engine failure on her Qantas Lockheed Super Constellation aircraft. Due to this, the Queen was unable to attend the ceremony. The 3,048 metres (10,000 ft) runway at the then Embakasi Airport was a big improvement on Eastleigh's 2,432 metres (7,979 ft) murram runway, which in

15128-543: Was powered by Pratt & Whitney JT3C turbojet engines. The JT3D-3B engines are readily identifiable by the large gray secondary-air inlet doors in the nose cowl. These doors are fully open (sucked in at the rear) during takeoff to provide additional air. The doors automatically close with increasing airspeed. The 707 was the first commercial jet aircraft to be fitted with clamshell-type thrust reversers . The 707 uses engine-driven turbocompressors to supply compressed air for cabin pressurization . On many commercial 707s,

15252-418: Was scheduled for 2017, after which JKIA was predicted to be able to handle 12 million passengers. This terminal serves mainly low-cost carrier airlines (LCCs). The prefabricated terminal opened in April 2015 with a capacity of 2.5M passengers. It was originally intended to relieve overcrowding. Terminal 2 houses international and domestic check-in desks and boarding gates. Current lounges at Terminal 2 include

15376-582: Was to be powered by four 22,500-pound-force thrust (100 kN) Pratt & Whitney JT3D-15 turbofan engines, and it would have had a nearly 10-foot (3.0 m) extension in wingspan, to 155.5 feet (47.4 m). Two variations were proposed, the 707-820(505) model and the 707-820(506) model. The 505 model would have had a fuselage 45 feet (14 m) longer than the 707-320B, for a total length of 198.6 feet (60.5 m). This model would have carried 209 passengers in mixed-class configuration and 260 passengers in all-economy configuration. The 506 model would have had
