) work together on their trijet designs, the 727 and D.H.121 Trident, respectively. The two designs had a similar layout, the 727 being slightly larger. At that time Boeing intended to use three Allison AR963 turbofan engines, license-built versions of the Rolls-Royce RB163 Spey used by the Trident. 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. De Havilland had wanted Boeing to license-build the D.H.121, while Boeing felt that the aircraft needed to be designed for the American market, with six-abreast seating and the ability to use runways as short as .

was looking for a customer for its new JT8D turbofan design study, based on its J52 (JT8A) turbojet, while United and Eastern were interested in a Pratt & Whitney alternative to the RB163 Spey. Once Pratt & Whitney agreed to go ahead with development of the JT8D, Eddie Rickenbacker, chairman of the board of Eastern, told Boeing that the airline preferred the JT8D for its 727s. Boeing had not offered the JT8D, as it was about heavier than the RB163, though slightly more powerful; the RB163 was also further along in development than the JT8D. Boeing reluctantly agreed to offer the JT8D as an option on the 727, and it later became the sole powerplant. With high-lift devicesEden, Paul. (Ed).

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.''Case Study in Aircraft Design; the Boeing 727'', American Institute of Aeronautics and Astronautics Professional Study Series, September 1978.

The 727 was successful with airlines worldwide partly because it could use smaller runways while still flying medium-range routes. This allowed airlines to carry passengers from cities with large populations, but smaller airports to worldwide tourist destinations. One of the features that gave the 727 its ability to land on shorter runways was its clean wing design. With no wing-mounted engines, leading-edge devices (Krueger, or hinged, flaps on the inner wing and extendable

of 3.0 (based on the flap-retracted wing area). The 727 was stable at very low speeds compared to other early jets, but some domestic carriers learned after review of various accidents that the 40° flap setting could result in a higher-than-desired sink rate or a stall on final approach. These carriers' Pilots' Operation Handbooks disallowed using more than 30° of flaps on the 727, even going so far as installing plates on the flap lever slot to prevent selection of more than 30° of flaps.


Noise

The 727 is one of the noisiest commercial jetliners, categorized as Stage 2 by the U.S. Noise Control Act of 1972, which mandated the gradual introduction of quieter Stage 3 aircraft. The 727's JT8D jet engines use older low-bypass turbofan technology, whereas Stage 3 aircraft use the more efficient and quieter high-bypass turbofan design. When the Stage 3 requirement was being proposed, Boeing engineers analyzed the possibility of incorporating quieter engines on the 727. They determined that the JT8D-200 engine could be used on the two side-mounted pylons. The JT8D-200 engines are much quieter than 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 ( fan diameter in the JT8D-200 compared to in the JT8D-1 through -17) into the fuselage at the number two engine location were prohibitive. Current regulations require that a 727, or any other Stage 2 noise jetliner in commercial service must be retrofitted with a hush kit to reduce engine noise to Stage 3 levels to continue to fly in U.S. airspace. These regulations have been in effect since December 31, 1999. One such hush kit is offered by

, and has been purchased by over 60 customers. Aftermarket winglet kits, originally developed by Valsan Partners and later marketed by Quiet Wing Corp. have been installed on many 727s to reduce noise at lower speeds, as well as to reduce fuel consumption. In addition, Raisbeck Engineering developed packages to enable 727s to meet the Stage 3 noise requirements. These packages managed to get light- and medium-weight 727s to meet Stage 3 with simple changes to the flap and slat schedules. For heavier-weight 727s, exhaust mixers must be added to meet Stage 3. American Airlines ordered and took delivery of 52 Raisbeck 727 Stage 3 systems. Other customers included TWA, Pan Am, Air Algérie, TAME, and many smaller airlines. Since September 1, 2010, 727 jetliners (including those with a hush kit) are banned from some Australian airports because they are too loud.


Operational history

In addition to domestic flights of medium range, the 727 was popular with international passenger airlines. The range of flights it could cover (and the additional safety added by the third engine) meant that the 727 proved efficient for short- to medium-range international flights in areas around the world. The 727 also proved popular with cargo and charter airlines.

Variants

''Data from: ''Boeing Aircraft since 1916'' The two series of 727 are the initial -100 (originally only two figures as in -30), which was launched in 1960 and entered service in February 1964, and the -200 series, which was launched in 1965 and entered service in December 1967.


727-100

The first 727-100 (N7001U) flew on February 9, 1963. FAA type approval was awarded on December 24 of that year, with initial delivery to United Airlines on October 29, 1963, to allow pilot training to commence. The first service was flown by Eastern Air Lines on February 1, 1964, between Miami, Washington, DC, and Philadelphia. A total of 571 Boeing 727-00/100 series aircraft were delivered (407 -100s, 53 -100Cs, and 111 -100QCs), the last in October 1972. One 727-100 was retained by Boeing, bringing total production to 572. The -100 designation was assigned retroactively to distinguish the original short-body version. Prior to the introduction of the 727-200, all short-body aircraft followed a "727-00" pattern. Aircraft were delivered for United Airlines as 727-22, for American Airlines as 727-23 and these designations were retained even after the advent of the 727-200. However, short-body aircraft ordered after the introduction of the 727-200 followed the new "727-100" pattern (i.e. 727-123 for American Airlines). ;727-100C Convertible passenger cargo version, additional freight door and strengthened floor and floor beams, three alternative fits: *94 mixed-class passengers *52 mixed-class passengers and four cargo pallets () *Eight cargo pallets () ;727-100QC QC stands for Quick Change.

727-200

A stretched version of the 727-100, the -200 is longer () than the -100 (). A fuselage section ("plug") was added in front of the wings and another 10 ft fuselage section was added behind them. The wing span and height remain the same on both the -100 and -200 (, respectively). The original 727-200 had the same maximum gross weight as the 727-100; however, as the aircraft evolved, a series of higher gross weights and more powerful engines were introduced along with other improvements, and from line number 881, 727-200s are dubbed -200 Advanced. The aircraft gross weight eventually increased from for the latest versions. The dorsal intake of the number-two engine was also redesigned to be round in shape, rather than oval as it was on the -100 series. The first 727-200 flew on July 27, 1967, and received FAA certification on November 30, 1967. The first delivery was made on December 14, 1967, to Northeast Airlines. A total of 310 727-200s were delivered before the -200 was replaced on the production line by the 727-200 Advanced in 1972. ;727-200C A convertible passenger cargo version; only one was built. ;727-200 Advanced The Advanced version of the 727-200 was introduced in 1970.

After only a few months, the concept was developed into the Boeing 7N7 design, which eventually became the
