The Boeing 727 is a medium to short-range single-aisle airliner, featuring 6 abreast seating. In the early stages, it was suggested that Boeing and de Havilland, which later became Hawker Siddeley, collaborate as both aircraft makers were developing a trijet airliner. The aircraft gross weight eventually increased from 169,000 to 209,500 pounds (76,700 to 95,000 kg) for the latest versions. This didn’t mean it came with a soft roof so much as it came with options for a mixed passenger/cargo payload.

AIRLINER SPOTTING GUIDE   |   BOEING VS AIRBUS SPOTTING TIPS What are the Specs of the Airbus A380 Super Jumbo? The nose is "pointed". This modification was originally developed by Valsan Partners, but was later marketed by Quiet Wing Technologies in Redmond, Washington. [25][26], Since September 1, 2010, 727 jetliners (including those with a hush kit) are banned from some Australian airports because they are too loud.[27]. Because of the middle engine being located in the rear of the fuselage, there was no room to change to a wider high bypass option. The first 727-200 flew on July 27, 1967, and received FAA certification on November 30, 1967. A cargo conversion for United Parcel Service, these were re-engined with Stage 3-compliant Rolls-Royce Tay turbofans. Aerial Firefighting with Fire Fighting Airplanes. [40] After the first delivery in mid-1972, Boeing eventually raised production to more than a hundred per year to meet demand by the late 1970s. The Boeing 727 is a tri-jet with an engine each side of the fuselage just adjacent to the leading edge of the tail fin. The 20 ft (6.1 m) longer variant typically carries 134 passengers in two classes over 2,550 nmi (4,720 km), or 155 in a single class. [14] With no wing-mounted engines, leading-edge devices (Krueger, or hinged, flaps on the inner wing and extendable leading edge slats out to the wingtip) and trailing-edge lift enhancement equipment (triple-slotted,[21] fowler flaps) could be used on the entire wing. Due to its clean aerodynamic lines, it was capable of maximum speeds around Mach .9 or better. A military version, the Boeing C-22, was operated as a medium-range transport aircraft by the Air National Guard and National Guard Bureau to airlift personnel. the 4800-ft runway at Key West International Airport). The Advanced featured improvements in lifting capacity through airframe strengthening, more powerful engines as well as an option for a longer range version with additional fuel carrying capacity. As of May 2020[update], a total of 13 Boeing 727s (1× 727-100s and 12× -200s) were in commercial service with 6 airlines, plus one in government and private use. [30], At the start of the 21st century, the 727 remained in service with a few large airlines. The compromise was reached and development began. Representatives from each company met and discussed the project, however, de Havilland wanted Boeing to make the Trident under licence, while Boeing for their part wanted an aircraft with 6 abreast seating and short runway abilities. Copyright © 2020 AirlinerSpotter.com  All Rights Reserved. One of the features that gave the 727 its ability to land on shorter runways was its clean wing design. This means that lift enhancing equipment can be applied to the whole wing with no gaps. (adsbygoogle = window.adsbygoogle || []).push({}); The Boeing 747 with its four engines, one full passenger deck the length of the fuselage, and bulbous front fuselage is an easy spot. Other customers included TWA, Pan Am, Air Algérie, TAME, and many smaller airlines. Of the passenger model of the 727-200 Advanced, a total of 935 were delivered, after which it had to give way to a new generation of aircraft.

The 727 proved to be such a reliable and versatile airliner that it came to form the core of many startup airlines' fleets. Included below is a table of the Boeing customer codes used for some larger and popular world airlines. The aircraft was then able to be used to haul freight during the night hours. These regulations have been in effect since December 31, 1999. [10], In 1960, Pratt & Whitney was looking for a customer for its new JT8D turbofan design study, based on its J52 (JT8A) turbojet,[11] while United and Eastern were interested in a Pratt & Whitney alternative to the RB163 Spey. Nosewheel brakes were available as an option to reduce braking distance on landing, which provided reduction in braking distances of up to 150 m (490 ft).[20]. The first 727-100 (N7001U) flew on February 9, 1963. [5], In 1959, Lord Douglas, chairman of British European Airways (BEA), suggested that Boeing and de Havilland Aircraft Company (later Hawker Siddeley) work together on their trijet designs, the 727 and D.H.121 Trident, respectively. Boeing wing strobe lights flash only once, while Airbus airliners flash twice in rapid succession. It also features a flat APU exhaust at the rear of the fuselage. Included on this page is a quick and easy guide to spotting the Boeing jetliners in use today by looking at details such as engine placement, tail design and landing gear configuration. The museum's previous 727-223, tail number N874AA, was donated to the National Airline History Museum in Kansas City and will be flown to its new home once FAA ferry approval is granted. Lastly, Eastern Airlines needed more than 2 engines as they had overwater routes to the Caribbean. Due to the engines being mounted much higher on the fuselage, they were further away from foreign objects being ingested than those of aircraft with engines slung under the wing. Boeing's current official name for the project is New Midsize Aircraft (NMA). [18] The 727 is equipped with a retractable tailskid that is designed to protect the aircraft in the event of an over-rotation on takeoff. This meant the 727 did not have to leave one of its engines running whilst on the ground to provide power. 2 x 2 wheel bogies underwing plus 2 wheeled nose gear. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. All but 5 are located within the United States. The 727 has proven to be popular where the airline serves airports with gravel, or otherwise lightly improved, runways. Boeing 747 8 Intercontinental and Freighter History.

Airbus A340, history of a long haul airliner.

Speed was increased by 50 mph (80 km/h) by replacing the two side engines with the JT8D-217 or the JT8D-219, which are also found on many MD-80s, along with the addition of hush kits to the center engine. The 727 had some military uses, as well. This was based on their requirement to operate out of their high, altitude hub at Denver. A quadjet, the 707 has a swept wing with podded engines. [48], Zero Gravity Corporation uses a modified 727-200 in reduced-gravity passenger carrying operations.[49]. Because the engines are mounted on the rear of the fuselage, this leaves the wings clear of any obstruction caused by engine pylons. These incidents caused the loss of 4,209 lives of which 345 were caused by 178 hijackings. The JT8D is a low bypass engine which made the 727 one of the noisiest commercial airliners. Inside this highly popular City Jet. To this end, the 727 was able to be self-sufficient. The 727 was designed as a follow-on to the Boeing 707 quad-jet airliner from which it borrowed the cockpit and some of the fuselage design. If you have any experiences you would like to share around the 727, we would love to hear them in the comments section below. The first delivery was made on December 14, 1967, to Northeast Airlines. The 727 was designed as a follow-on to the Boeing 707 quad-jet airliner from which it borrowed the cockpit and some of the fuselage design. First, the aerodynamics of the wings. The 727 is one of the noisiest commercial jetliners, categorized as Stage 2 by the U.S. The 727-200 was also offered in a variant called the 727-200 Advanced. One can spot a Boeing jet airliner in nearly any airport in the world. A feature called the Cooper Vane was added after 1971 to prevent the door opening in flight. The Advanced version of the 727-200 was introduced in 1970. This is obviously lost revenue as far as utilising cabin space for paid seats is concerned.

After only a few months the concept was developed into the Boeing 7N7 design which eventually became the Boeing 757. Aircraft were delivered for United Airlines as 727-22, for American Airlines as 727-23, and so on (not -122, -123, etc.) The JT8D-200 engines are much quieter then the original JT8D-1 through -17 variant engines that power the 727, as well as more fuel efficient due to the higher bypass ratio, but the structural changes to fit the larger-diameter engine (49.2 inches (125 cm) fan diameter in the JT8D-200 compared to 39.9 inches (101 cm) in the JT8D-1 through -17) into the fuselage at the number two engine location were prohibitive. Also, the 787 does not have winglets or sharklets, which are used on the similar shaped Airbus A350. Originally a prototype, it was later sold to United Airlines, which donated it to the Museum of Flight in Seattle in 1991. They determined that the JT8D-200 engine could be used on the two side-mounted pylons. Boeing 737 Interior. Actual aircraft followed a "727-00" pattern. Note that the 777-200 has four cabin doors while the 777-300 has five cabin doors. ……. This allowed airlines to carry passengers from cities with large populations, but smaller airports to worldwide tourist destinations. [7][8] Boeing and de Havilland each sent engineers to the other company's locations to evaluate each other's designs, but Boeing eventually decided against the joint venture. In addition, the 727 has seen sporadic government use, having flown for the Belgian, Yugoslav, Mexican, New Zealand, and Panama air forces, among the small group of government agencies that have used it. Today those speeds are rarely seen as the economics of flying those speeds at today’s’ fuel prices are not viable. The 200 was 6.1 metres (20 feet) longer than the 727-100 and together they enabled the 727 to cover the 120 to 180 seat market. This honour was taken by the Boeing 737 in the early 1990s. The airlines were; United Airlines, Eastern Airlines and American Airlines. [17] This S-duct proved to be troublesome in that flow distortion in the duct induced a surge in the centerline engine on the take-off of the first flight of the 727-100. One example would be Emirates Boeing 777-31H. Launched in 1965, the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that December. Boeing 737 History, the story behind this hugely successful City Jet. It was succeeded by the 757-200 and larger variants of the 737. [33][34][35] The Federal Aviation Administration granted the museum a special permit for the 15-minute flight. This is similar to the convertible version with a roller-bearing floor for palletised galley and seating and/or cargo to allow much faster changeover time (30 minutes). The first 727-100 rolled out November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964. Eastern Airlines wanted a third engine for its overwater flights to the Caribbean, since at that time twin-engine commercial flights were limited by regulations to routes with 60-minute maximum flying time to an airport (see ETOPS). ……needed more than 2 engines as they had over-water routes…. 707 - Narrow bodied,4 engines. The success of the 707 in the 1960s made Boeing the early leader in commercial airliners, and led to a popular 7x7 family of jetliners introduced over the years: the 717, 727, 737, 747, 757, 767, 777, and the 787 Dreamliner. United did not proceed with its order and Indian Airlines instead ordered the larger Airbus A300, so the project was cancelled in 1976. American Airlines Boeing airliners awaiting takeoff at the DFW International Airport. The high-mounted engines greatly reduce the risk of foreign object damage.
