[72] The last delivery of a 737-200 aircraft was in August 1988 to Xiamen Airlines. The 737 Classic series featured CFM56 high bypass turbofan engines, which yielded significant gains in fuel economy and a reduction in noise over the JT8D low bypass engines used on the 737 Original series (−100 and −200), but also posed an engineering challenge given the low ground clearance of the Boeing 737 family. [18][19] It was the first aircraft to have, as part of its initial certification, approval for Category II approaches,[20] which refers to a precision instrument approach and landing with a decision height between 98 to 197 feet (30 to 60 m). These enhanced short runway versions could increase pay or fuel loads when operating on runways under 5,000 feet (1,500 m). [88][89] The 737 MAX 7 replaced the 737-700 and was predicted to carry 12 more passengers and fly 400 nmi (740 km) farther than Airbus A319neo with 7% lower operating costs per seat.[90]. This reduced the downforce on the main wheels thereby reducing the effectiveness of the wheel brakes. [58] The last two -400s, i.e. contém as seguintes caracteristicas: 1,70 m de envergadura 1,80 de fuselagem duas edf duct fun … Two additional aircraft were delivered to the Colorado Air National Guard at Buckley ANGB (later Buckley AFB) and Peterson AFB, Colorado, in direct support of cadet air navigation training at the nearby U.S. Air Force Academy. 737 Classic: 737-300, 737-400, 737-500. The main cabin (where the passengers sit) was also made better. The plane could now carry 149 passengers, because the fuselage of the plane was made bigger. The sides of the tires are exposed to the air in flight. In 1980, preliminary aircraft specifications of the variant, dubbed 737-300, were released at the Farnborough Airshow. The P-8 Poseidon (formerly Multimission Maritime Aircraft) developed for the United States Navy by Boeing Defense, Space & Security, based on the Next Generation 737-800ERX. The -700 seats 126 passengers in a two-class or 149 passengers in a one-class layout. Many countries use the 737 as a military plane. ", "Boeing officially launches re-engined 737. On average, somewhere in the world, a 737 took off or landed every five seconds in 2006. Since entering service in 1968, the 737 has carried over 12 billion passengers over 74 billion miles (120 billion km; 65 billion nm), and has accumulated more than 296 million hours in the air. Only 30 -100s were ever made.[19]. The NMA project was set aside in January 2020, as Boeing focused on returning the 737 MAX to service and announced that it would be taking a new approach to future projects.[109]. The -300 can usually hold 128 passengers. [55] The 737-300 retrofitted with Aviation Partners' winglets was designated the -300SP (Special Performance). The 737 has also been in 106 hijackings. The Boeing 737 Classic is the name of the 737-300/-400/-500. The -100 was finished on January 17, 1967. [127] The next generation 737, 737 MAX, will feature an Advanced Technology (AT) Winglet that is produced by Boeing. Introduced in 1997, the 737 Next Generation (NG) -600/700/800/900 variants have updated CFM56-7s, a larger wing and an upgraded glass cockpit, and seat 108 to 215 passengers. [18] Lufthansa got its first 737 on December 28, 1967. Launched in 1980 and introduced in 1984, the 737 Classic -300/400/500 variants were re-engined with CFM56-3 turbofans and offered 110 to 168 seats. En una grabación de cabina, se puede escuchar a Engineer Joe Sutter relocated the engines to the wings, lightening the wing structure and simplifying the accommodation of six-abreast seating in the fuselage. The -200 was basically just a longer version of the 737-100. Boeing establece rangos máximos de 6100, 7900, 7700 y 7260 millas respectivamente para cada modelo de 747. They proved to be relatively ineffective and tended to lift the aircraft up off the runway when deployed. 738: 186. The MAX-7 will replace the 737-700, the MAX-8 will replace the 737-800 and the MAX-9 will replace the 737-900ER. They are fitted at the end of the wing and help the engines to burn less fuel because they reduce drag. [140] The name was short-lived. L aggiornamento della velocità è ritardato di qualche secondo [9] Boeing did a lot of research and found that airlines wanted an airliner which could hold 50 to 60 passengers. [18] Lufthansa was the only significant customer to purchase the 737-100 and only 30 aircraft were produced. This was in 1970. [45][46][47] This intensified the competition between the two giant aircraft manufacturers, which has since become a duopoly competition. It filled also the gap left by Boeing's decision to discontinue the MD-80 and MD-90 aircraft, following Boeing's merger with McDonnell Douglas. [66][67] Overhead bins which move have been installed. They can also be added when the aircraft is built. On July 20, 2011, Boeing announced plans for a third major upgrade and respectively fourth generation of 737 series to be powered by the CFM LEAP-1B engine, with American Airlines intending to order 100 of these aircraft. It first flew on February 9, 1997. At that time, twelve customers had ordered the package for more than 250 airframes. Southwest Airlines flew their first flight of a 737-800 with Split Scimitar winglets on April 14, 2014. [34] The variant still sees regular service through North American charter operators such as Sierra Pacific. The 737's main landing gear (wheels) go into holes at the bottom of the plane. [31] Boeing also provided the 737-200C (Combi), which allowed for conversion between passenger and cargo use and the 737-200QC (Quick Change), which facilitated a rapid conversion between roles. The first airline to use it was Piedmont Airlines. The latest generation, the 737 MAX -7/8/9/10, powered by improved CFM LEAP-1B high bypass turbofans and accommodating 138 to 204 people, entered service in 2017. Boeing wanted to allow the aircraft to hold more passengers and travel further. Winglets can be fitted to 737s which do not have them already installed. [163], In 2016, there were 6,512 737 airliners in service (5,567 737NGs plus 945 737-200s and 737 Classics), more than the 6,510 A320 family. It has the body of a 737-700, but the wings and landing gear of a 737-800. [14][15], The first Boeing 737-100 prototype was ready in 1966. O consumo … These new brakes have been allowed by the Federal Aviation Administration. As of January 1, 2001, 1,945 are in service. Adding a fuel dump system to the bigger 737s would make the plane much heavier. [50] This first major upgrade series was later renamed to the 737 Classic series. These winglets stand approximately 8 feet (2.4 m) tall and are installed at the wing tips. exist, they are no longer needed. [11], On April 5, 1965, Boeing announced that United Airlines had ordered 40 737s. Winglets can help a plane burn up to 5% less fuel. The main development was to re-engine with the high pressure ratio CFM56-7. A third aircraft was also transferred to Air Force Material Command for use as a radar test bed aircraft and was redesignated as an NT-43A. They were used as Maritime reconnaissance (MPA)/transport aircraft, fitted with SLAMMAR (Side-looking Multi-mission Airborne Radar). [31] The 737-400's first flight was on February 19, 1988. In 1970, Boeing only got 37 orders for 737s. [10] Many designs for the engine attachment strut were tested in the wind tunnel and the optimal shape for high speed was found to be one which was relatively thick, filling the narrow channels formed between the wing and the top of the nacelle, particularly on the outboard side. ", "Continental Airlines Is First North American Carrier to Fly With Boeing's New Sky Interior. Boeing 737 je úzkotrupé dvoumotorové proudové dopravní letadlo pro krátké a střední vzdálenosti. [52], On July 20, 2011, Boeing said that they were working on a new 737 version, which would have the CFM International LEAP engine. Seating is as follows: A319: 141. [97], This information comes from: Boeing 737 specifications,[98] 737 Airport Planning Report,[99] b737.org.uk site. [36] Winglets can be added to most 737NG models. [106], In the late 2010s, Boeing worked on a medium-range Boeing New Midsize Airplane (NMA) with two variants seating 225 or 275 passengers and targeting the same market segment as the 737 MAX 10 and the Airbus A321 neo. The Boeing AT Winglet resembles a cross between the Blended Winglet and the Split Scimitar Winglet.[128]. [100] The variant configuration with a predicted 5% lower trip cost and seat cost compared to the A321neo was firmed up by February 2018, and by mid-2018, the critical design review was completed. The first aircraft was delivered to Scandinavian Airlines on September 18, 1998. Boeing 737 MAX je čtvrtá generace dvoumotorového proudového úzkotrupého dopravního letounu Boeingu 737 na krátké a střední tratě vyvinutá Boeingem jako reakce na úspěch Příští generace (Next Generation) Boeingů 737-700, 800 a 900. [120], The 737 is unusual in that it still uses a hydro-mechanical flight control system, similar to the Boeing 707 and typical of the period, that transmits pilot commands to control surfaces by steel cables run through the fuselage and wings rather than by an electrical fly-by-wire system as used in all of the Airbus fleet and all later Boeing models. Informally referred to as the Gator (an abbreviation of "navigator") and "Flying Classroom", nineteen of these aircraft were delivered to the Air Training Command at Mather AFB, California during 1973 and 1974. 2011 decemberéig több mint 7000 megrendeléssel (a 6000-iket 2009 áprilisában adták át). However, because autopilot, advanced radar etc. Boeing made a different type of 737 for United, which was longer. 1,114 aircraft were made and the last one was delivered to Xiamen Airlines on August 8, 1988. Takeoff payloads were increased by up to 2,000 lbs on the 737-800 and 737-900ER and up to 400 lbs on the 737-600 and 737-700. By doing this, Boeing kept enough money to keep the 737 project going. Since the engine is close to the ground, it is possible that they can be damaged by things lying on the ground. [4], Boeing had been studying short-haul jet aircraft designs, and saw a need for a new aircraft to supplement the 727 on short and thin routes. It looked similar to the cabin of a Boeing 757. In this mode, the servo tabs aerodynamically control the elevators and ailerons; these servo tabs are in turn controlled by cables running to the control yoke. (Project 2A2H). This 148-inch (3.76 m) wide fuselage cross-section permitted six-abreast seating compared to the rivals' five-abreast. [73][74][75] [36][38] A, Boeing delivered the 5,000th 737 to Southwest Airlines on February 13, 2006. The first aircraft used by Boeing as prototype under registration N73700 was later ordered by and delivered to NASA on July 26, 1973, which then operated it under registration N515NA and retired after 30 years on September 27, 2003. These models go from 102 ft (31.09 m) to 138 ft (42.06 m) in length. The 737-200 Advanced is an improved version of the -200. Instead, if the emergency is not very serious, 737s fly around in circles to get rid of fuel. At first, Boeing was making it to be a shorter, cheaper airliner than its 707 and 727. Reprinted in the AIAA Journal of Aircraft, Vol.3 No.6, November/December 1966, pp.524-528. [1][73], The 737-400F was a 737-400 changed into a cargo plane. It also wanted to make improvements to make the aircraft more modern. [42] In late 1993, after engineering trade studies and discussions with major customers, Boeing proceeded to launch the third derivative of the Boeing 737, the 737 Next Generation (NG) -600/700/800/900 series. The fourth generation 737 MAX series, launched August 2011. [76] The 737-300 series was made until 1999. [82] Boeing launched the 737-700ER on January 30, 2006. SAS reports a mere 0.001 difference in fuel burn per seat per kilometer in litres in favor of Boeing in each case–despite the 738 having 18 more seats, in which case the difference could be expected to be much greater. [148], Boeing delivered 8,918 of the 737 family between March 1988 and December 2018,[149][150] while Airbus delivered 8,605 A320 family aircraft over a similar period since first delivery in early 1988. Over 10,000 737s have been ordered by airlines. These are smaller windows which are above the main windows. [174][better source needed] The 737 MAX backlog fell by 182, mainly due to the Jet Airways bankruptcy, a drop in Boeing's airliner backlog was a first in at least the past 30 years. This page was last changed on 8 July 2020, at 08:35. 737s fly to 1,200 places in 190 countries. [79], The 737-600's rivals are the Airbus A318, Embraer 195 and Sukhoi Superjet 100. [77][78] The first delivery was a MAX 8 on May 6, 2017 to Lion Air's subsidiary Malindo Air,[79] which put it into service on May 22, 2017.
