For over a decade, more 727s were built per year than any other jet airliner; in 1984, production ended with 1,832 built and 1,831 delivered, the highest total for any jet airliner until the 737 surpassed it in the early 1990s. The airliner's middle engine (engine 2) at
8710-631: The Boeing 727. Production ended in September 1984 with 1,832 having been built. The Boeing 727 design was a compromise among United Airlines , American Airlines , and Eastern Air Lines ; each of the three had developed requirements for a jet airliner to serve smaller cities with shorter runways and fewer passengers. United Airlines requested a four-engine aircraft for its flights to high-altitude airports, especially its hub at Stapleton International Airport in Denver, Colorado . American Airlines, which
8844-532: The Great and developed from the Moscow ( Middle or Central Russian ) dialect substratum under the influence of some of the previous century's Russian chancery language. Prior to the Bolshevik Revolution , the spoken form of the Russian language was that of the nobility and the urban bourgeoisie. Russian peasants, the great majority of the population, continued to speak in their own dialects. However,
8978-590: The Institute of Russian Language of the Russian Academy of Sciences, an optional acute accent ( знак ударения ) may, and sometimes should, be used to mark stress . For example, it is used to distinguish between otherwise identical words, especially when context does not make it obvious: замо́к ( zamók – "lock") – за́мок ( zámok – "castle"), сто́ящий ( stóyashchy – "worthwhile") – стоя́щий ( stoyáshchy – "standing"), чудно́ ( chudnó – "this
9112-649: The JT8D, as it was about 1,000 lb (450 kg) 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 devices on its wing, the 727 could use shorter runways than most earlier jets (e.g. the 4800-ft runway at Key West International Airport ). Later 727 models were stretched to carry more passengers and replaced earlier jet airliners such as
9246-526: The Middle East and North Africa – 1.3 million, Sub-Saharan Africa – 0.1 million, Latin America – 0.2 million, U.S., Canada , Australia, and New Zealand – 4.1 million speakers. Therefore, the Russian language is the seventh-largest in the world by the number of speakers , after English, Mandarin, Hindi -Urdu, Spanish, French, Arabic, and Portuguese. Russian is one of the six official languages of
9380-807: The Russian alphabet include ⟨ ѣ ⟩ , which merged to ⟨ е ⟩ ( /je/ or /ʲe/ ); ⟨ і ⟩ and ⟨ ѵ ⟩ , which both merged to ⟨ и ⟩ ( /i/ ); ⟨ ѳ ⟩ , which merged to ⟨ ф ⟩ ( /f/ ); ⟨ ѫ ⟩ , which merged to ⟨ у ⟩ ( /u/ ); ⟨ ѭ ⟩ , which merged to ⟨ ю ⟩ ( /ju/ or /ʲu/ ); and ⟨ ѧ ⟩ and ⟨ ѩ ⟩ , which later were graphically reshaped into ⟨ я ⟩ and merged phonetically to /ja/ or /ʲa/ . While these older letters have been abandoned at one time or another, they may be used in this and related articles. The yers ⟨ ъ ⟩ and ⟨ ь ⟩ originally indicated
9514-458: The Russian principalities before and especially during Mongol rule. This strengthened dialectal differences, and for a while, prevented the emergence of a standardized national language. The formation of the unified and centralized Russian state in the 15th and 16th centuries, and the gradual re-emergence of a common political, economic, and cultural space created the need for a common standard language. The initial impulse for standardization came from
9648-458: The Soviet era can speak Russian, other generations of citizens that do not have any knowledge of Russian. Primary and secondary education by Russian is almost non-existent. In Uzbekistan , Russian is the language of inter-ethnic communication. It has some official roles, being permitted in official documentation and is the lingua franca of the country and the language of the elite. Russian
9782-512: 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
9916-661: The Tu-154 (B variant) until the fatal fire incident in Surgut had been investigated. Its operation in Iran ceased in February 2011 due to a number of crashes and incidents involving the type (almost 9% of all Tu-154 losses have occurred in Iran). This grounding compounded the effects of US embargo on civil aircraft parts, substantially decreasing the number of airworthy aircraft in the Iranian civil fleet. In 2010 there were two fatal losses of
10050-463: The Tu-154 cannot be modified to meet the current Stage III noise regulations , so are no longer allowed to fly into airspace where such regulations are enforced, such as the European Union, but the Tu-154M's D-30 engines can be fitted with hush kits , allowing them to meet noise regulations. Many variants of this airliner have been built. Like its Western counterpart, the Boeing 727, many of
10184-540: The Tu-154 due to pilot error and/or weather conditions (a Polish presidential jet attempting a rural airfield landing in heavy fog, the 2010 Polish Air Force Tu-154 crash , and a Russian-registered plane that suffered engine stall after a crew member accidentally de-activated a fuel transfer pump). Following these accidents, in March 2011 the Russian Federal Bureau of Aviation recommended a withdrawal of remaining Tu-154Ms from service. On 27 December 2016,
10318-478: The Tu-154s in service have been hush-kitted, and some converted to freighters. As of August 2017, there were 44 Tupolev Tu-154 aircraft of all variants still in civil, governmental or military service. A 45th aircraft has been sighted flying with Air Kyrgyzstan in 2017, but is not listed by the airline as part of its fleet. A 46th aircraft, a Polish Tu-154 with operational number 102, is currently in storage at
10452-467: The United Nations. Education in Russian is still a popular choice for both Russian as a second language (RSL) and native speakers in Russia, and in many former Soviet republics. Russian is still seen as an important language for children to learn in most of the former Soviet republics. In Belarus , Russian is a second state language alongside Belarusian per the Constitution of Belarus . 77% of
10586-564: The aft stair could be opened in flight, the Central Intelligence Agency used them to drop agents and supplies behind enemy lines in Vietnam . In early 1988, The Iraqi Air Force modified a Boeing 727 by fitting it with Thomson-CSF TMV-018 Syrel pods for ESM and Raphael-TH pods with side looking radar . Known as 'Faw-727', it was reportedly used as an ELINT platform in the invasion of Kuwait in 1990 (during which it
10720-516: The airplane struck snow plows on the runway), cargo overloading in the lapse of post-Soviet federal safety standards, and mid-air collisions due to faulty air traffic control . Other incidents resulted from mechanical problems, running out of fuel on unscheduled routes, pilot errors (including inadequate flight training for new crews), and cargo fires; several accidents remain unexplained. On 2 January 2011, Russia's Federal Transport Oversight Agency advised airlines to stop using remaining examples of
10854-450: The airstair could not be lowered in flight. The design included an auxiliary power unit (APU), which allowed electrical and air-conditioning systems to run independently of a ground-based power supply, and without having to start one of the main engines. An unusual design feature is that the APU is mounted in a hole in the keel beam web, in the main landing gear bay. The 727 is equipped with
10988-516: The backbone of its fleet until the 2000s; FedEx began replacing them with Boeing 757s in 2007. Many cargo airlines worldwide employ the 727 as a workhorse, since, as it is being phased out of U.S. domestic service because of noise regulations, it becomes available to overseas users in areas where such noise regulations have not yet been instituted. Charter airlines Sun Country , Champion Air , and Ryan International Airlines all started with 727 aircraft. The 727 had some military uses as well. Since
11122-403: The broader sense of expanding the use of Russian alongside or in favour of other languages. The current standard form of Russian is generally regarded as the modern Russian literary language ( современный русский литературный язык – "sovremenny russky literaturny yazyk"). It arose at the beginning of the 18th century with the modernization reforms of the Russian state under the rule of Peter
11256-485: The contemporary Boeing 727 have dihedral (upward sweep). The anhedral means that Russian airliners have poor lateral stability compared to their Western counterparts, but also are more resistant to Dutch roll tendencies. Considerably heavier than its predecessor Soviet-built airliner, the Ilyushin Il-18 , the Tu-154 was equipped with an oversized landing gear to reduce ground load, enabling it to operate from
11390-572: The country. There is an Israeli TV channel mainly broadcasting in Russian with Israel Plus . See also Russian language in Israel . Russian is also spoken as a second language by a small number of people in Afghanistan . In Vietnam , Russian has been added in the elementary curriculum along with Chinese and Japanese and were named as "first foreign languages" for Vietnamese students to learn, on equal footing with English. The Russian language
11524-413: The factory and the industrial plant their local peasant dialects with their phonetics, grammar, and vocabulary, and the very process of recruiting workers from peasants and the mobility of the worker population generate another process: the liquidation of peasant inheritance by way of leveling the particulars of local dialects. On the ruins of peasant multilingual, in the context of developing heavy industry,
11658-456: The final reading amendments that state that all schools and kindergartens in the country are to transition to education in Latvian . From 2025, all children will be taught in Latvian only. On 28 September 2023, Latvian deputies approved The National Security Concept, according to which from 1 January 2026, all content created by Latvian public media (including LSM ) should be only in Latvian or
11792-692: The generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union , the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to
11926-480: The government bureaucracy for the lack of a reliable tool of communication in administrative, legal, and judicial affairs became an obvious practical problem. The earliest attempts at standardizing Russian were made based on the so-called Moscow official or chancery language, during the 15th to 17th centuries. Since then, the trend of language policy in Russia has been standardization in both the restricted sense of reducing dialectical barriers between ethnic Russians, and
12060-467: 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
12194-490: The impression of an oval interior, with a lower ceiling than is common on Boeing and Airbus airliners. The passenger cabin accommodates 128 passengers in a two-class layout and 164 passengers in single-class layout, and up to 180 passengers in high-density layout. The layout can be modified to a winter version where some seats are taken out and a wardrobe is installed for passenger coats. The passenger doors are smaller than on its Boeing and Airbus counterparts. Luggage space in
12328-457: 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. 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 727 passenger service
12462-451: The inner wing and extendable leading edge slats out to the wingtip) and trailing-edge lift enhancement equipment (triple-slotted, Fowler flaps ) could be used on the entire wing. Together, these high-lift devices produced a maximum wing lift coefficient 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
12596-405: The larger Airbus A300 , so the project was cancelled in 1976. A concept with a 155-foot (47 m) fuselage and two high-bypass turbofan engines under the wings (but retaining the T tail) was proposed in 1977. More compact systems, a redesign of the internal space, and removing the need for the flight engineer would have increased the capacity to 189 seats in a two-class configuration. After only
12730-578: The military airport in Mińsk Mazowiecki . It was operated by 36th Special Aviation Regiment , but after the 2010 Polish Air Force Tu-154 crash of the Tu-154 101, the Regiment has been disbanded and the plane was grounded. It was fully operational, but the government decided not to use or sell it until the investigation into the Smoleńsk crash is finished. As of June 2021 the aircraft is not flying, and it
12864-431: The new aircraft. 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. 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
12998-524: The northwestern Xinjiang Uyghur Autonomous Region . Russian was also the main foreign language taught in school in China between 1949 and 1964. In Kazakhstan , Russian is not a state language, but according to article 7 of the Constitution of Kazakhstan its usage enjoys equal status to that of the Kazakh language in state and local administration. The 2009 census reported that 10,309,500 people, or 84.8% of
13132-515: The other hand, before the war, almost a quarter of Ukrainians were in favour of granting Russian the status of the state language, while after the beginning of Russia's invasion the support for the idea dropped to just 7%. In peacetime, the idea of raising the status of Russian was traditionally supported by residents of the south and east . But even in these regions, only a third of the respondents were in favour, and after Russia's full-scale invasion , their number dropped by almost half. According to
13266-461: The other three languages in the East Slavic branch. In many places in eastern and southern Ukraine and throughout Belarus, these languages are spoken interchangeably, and in certain areas traditional bilingualism resulted in language mixtures such as Surzhyk in eastern Ukraine and Trasianka in Belarus. An East Slavic Old Novgorod dialect , although it vanished during the 15th or 16th century,
13400-517: The overhead compartments is very limited. Like the Tupolev Tu-134 , the Tu-154 has a wing swept back at 35° at the quarter- chord line. The British Hawker Siddeley Trident has the same sweepback angle, while the Boeing 727 has a slightly smaller sweepback angle of 32°. The wing also has anhedral (downward sweep) which is a distinguishing feature of Russian low-wing airliners designed during this era. Most Western low-wing airliners such as
13534-446: The parliament approved a bill to close up all Russian language schools and kindergartens by the school year. The transition to only Estonian language schools and kindergartens will start in the 2024-2025 school year. In Latvia , Russian is officially considered a foreign language. 55% of the population was fluent in Russian in 2006, and 26% used it as the main language with family, friends, or at work. On 18 February 2012, Latvia held
13668-453: The peasants' speech was never systematically studied, as it was generally regarded by philologists as simply a source of folklore and an object of curiosity. This was acknowledged by the noted Russian dialectologist Nikolai Karinsky , who toward the end of his life wrote: "Scholars of Russian dialects mostly studied phonetics and morphology. Some scholars and collectors compiled local dictionaries. We have almost no studies of lexical material or
13802-459: The population aged 15 and above, could read and write well in Russian, and understand the spoken language. In October 2023, Kazakhstan drafted a media law aimed at increasing the use of the Kazakh language over Russian, the law stipulates that the share of the state language on television and radio should increase from 50% to 70%, at a rate of 5% per year, starting in 2025. In Kyrgyzstan , Russian
13936-418: The population was fluent in Russian in 2006, and 67% used it as the main language with family, friends, or at work. According to the 2019 Belarusian census , out of 9,413,446 inhabitants of the country, 5,094,928 (54.1% of the total population) named Belarusian as their native language, with 61.2% of ethnic Belarusians and 54.5% of ethnic Poles declaring Belarusian as their native language. In everyday life in
14070-479: The pronunciation of ultra-short or reduced /ŭ/ , /ĭ/ . Because of many technical restrictions in computing and also because of the unavailability of Cyrillic keyboards abroad, Russian is often transliterated using the Latin alphabet. For example, мороз ('frost') is transliterated moroz , and мышь ('mouse'), mysh or myš' . Once commonly used by the majority of those living outside Russia, transliteration
14204-472: The proper pronunciation of uncommon words or names. Russian is an East Slavic language of the wider Indo-European family . It is a descendant of Old East Slavic , a language used in Kievan Rus' , which was a loose conglomerate of East Slavic tribes from the late 9th to the mid-13th centuries. From the point of view of spoken language , its closest relatives are Ukrainian , Belarusian , and Rusyn ,
14338-447: The remaining operators are: In January 2010 Russian flag carrier Aeroflot announced the retirement of its Tu-154 fleet after 40 years, with the last scheduled flight being Aeroflot Flight 736 from Yekaterinburg to Moscow on 31 December 2009. In December 2010, Uzbekistan Airways also declared that it was retiring its Tu-154s. In February 2011, all remaining Iranian Tu-154s were grounded after two incidents. On 27 December 2016,
14472-491: The respondents), while according to the 2002 census – 142.6 million people (99.2% of the respondents). In Ukraine , Russian is a significant minority language. According to estimates from Demoskop Weekly, in 2004 there were 14,400,000 native speakers of Russian in the country, and 29 million active speakers. 65% of the population was fluent in Russian in 2006, and 38% used it as the main language with family, friends, or at work. On 5 September 2017, Ukraine's Parliament passed
14606-530: The risk of foreign object damage . 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. A total of three C-22Bs were in use, all assigned to the 201st Airlift Squadron , District of Columbia Air National Guard . At the start of the 21st century, the 727 remained in service with
14740-415: The same runways. The aircraft has two six-wheel main bogies fitted with large, low-pressure tires that retract into pods extending from the trailing edges of the wings (a common Tupolev feature), plus a two-wheel nose gear unit. Soft oleo struts ( shock absorbers ) provide a much smoother ride on bumpy airfields than most airliners, which very rarely operate on such poor surfaces. The original requirement
14874-430: The standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries. The aircraft has a cruising speed of 850 km/h (460 kn; 530 mph) and a range of 5,280 km (3,280 mi). Capable of operating from unpaved and gravel airfields with only basic facilities, it
15008-679: The survey carried out by RATING in August 2023 in the territory controlled by Ukraine and among the refugees, almost 60% of the polled usually speak Ukrainian at home, about 30% – Ukrainian and Russian, only 9% – Russian. Since March 2022, the use of Russian in everyday life has been noticeably decreasing. For 82% of respondents, Ukrainian is their mother tongue, and for 16%, Russian is their mother tongue. IDPs and refugees living abroad are more likely to use both languages for communication or speak Russian. Nevertheless, more than 70% of IDPs and refugees consider Ukrainian to be their native language. In
15142-459: The syntax of Russian dialects." After 1917, Marxist linguists had no interest in the multiplicity of peasant dialects and regarded their language as a relic of the rapidly disappearing past that was not worthy of scholarly attention. Nakhimovsky quotes the Soviet academicians A.M Ivanov and L.P Yakubinsky, writing in 1930: The language of peasants has a motley diversity inherited from feudalism. On its way to becoming proletariat peasantry brings to
15276-458: 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 (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
15410-786: The two. Others divide the language into three groupings, Northern , Central (or Middle), and Southern , with Moscow lying in the Central region. The Northern Russian dialects and those spoken along the Volga River typically pronounce unstressed /o/ clearly, a phenomenon called okanye ( оканье ). Besides the absence of vowel reduction, some dialects have high or diphthongal /e⁓i̯ɛ/ in place of Proto-Slavic * ě and /o⁓u̯ɔ/ in stressed closed syllables (as in Ukrainian) instead of Standard Russian /e/ and /o/ , respectively. Another Northern dialectal morphological feature
15544-511: The use of the language has some presence in certain areas. A large part of the population, especially the older generations, can speak Russian as a foreign language. However, English has replaced Russian as lingua franca in Lithuania and around 80% of young people speak English as their first foreign language. In contrast to the other two Baltic states, Lithuania has a relatively small Russian-speaking minority (5.0% as of 2008). According to
15678-471: The very rear of the fuselage gets air from an inlet ahead of the vertical fin through an S-shaped duct . 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. This was fixed by the addition of several large vortex generators in the inside of the first bend of the duct. The 727 was designed for smaller airports, so independence from ground facilities
15812-402: The wing as the higher fuselage height of the center section was simply retained towards the rear. 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). The 727 proved to be such a reliable and versatile airliner that it came to form the core of many startup airlines' fleets. The 727
15946-697: The world's ninth-most spoken language by total number of speakers . Russian is one of two official languages aboard the International Space Station , one of the six official languages of the United Nations , as well as the fourth most widely used language on the Internet . Russian is written using the Russian alphabet of the Cyrillic script ; it distinguishes between consonant phonemes with palatal secondary articulation and those without—the so-called "soft" and "hard" sounds. Almost every consonant has
16080-679: Was also stipulated as a requirement. Conceptually similar to the British Hawker Siddeley Trident , which first flew in 1962, and the American Boeing 727 , which first flew in 1963, the medium-range Tu-154 was marketed by Tupolev at the same time as Ilyushin was marketing its long-range Ilyushin Il-62 . The Soviet Ministry of Aircraft Industry chose the Tu-154, as it incorporated the latest in Soviet aircraft design and best met Aeroflot's anticipated requirements for
16214-526: Was an important requirement. This led to one of the 727's most distinctive features: the built-in airstair that opens from the rear underbelly of the fuselage, which initially could be opened in flight. Hijacker D. B. Cooper used this hatch when he parachuted from the back of a 727, as it was flying over the Pacific Northwest . Boeing subsequently modified the design with the Cooper vane so that
16348-588: Was briefly locked on by a Kuwaiti Mirage F1 on August 2) and the subsequent Iraqi monitoring of Coalition forces during Desert Shield . The 727 has proven to be popular where the airline serves airports with gravel, or otherwise lightly improved, runways. The Canadian airline First Air , for example, previously used a 727-100C to serve the communities of Resolute Bay and Arctic Bay in Nunavut, whose Resolute Bay Airport and former Nanisivik Airport both have gravel runways. The high-mounted engines greatly reduce
16482-686: Was developed to meet Aeroflot's requirement to replace the jet -powered Tu-104 and the Antonov An-10 and Ilyushin Il-18 turboprops . The requirements called for either a payload capacity of 16–18 t (35,000–40,000 lb) with a range of 2,850–4,000 km (1,540–2,160 nmi) while cruising at 900 km/h (490 kn), or a payload of 5.8 t (13,000 lb) with a range of 5,800–7,000 km (3,100–3,800 nmi) while cruising at 850 km/h (460 kn). A take-off distance of 2,600 m (8,500 ft) at maximum takeoff weight
16616-714: Was donated to the National Airline History Museum in Kansas City and was planned to be flown to its new home once FAA ferry approval was granted. After a series of financial problems with the restoration, N874AA was seized by Boeing Field for nonpayment of storage fees in 2021 and subsequently broken up and scrapped. Iran Aseman Airlines , the last passenger airline operator, made the worldwide last scheduled 727 passenger flight on January 13, 2019 between Zahedan and Tehran . Data from: Boeing Aircraft since 1916 The two series of 727 are
16750-405: Was first introduced in North America when Russian explorers voyaged into Alaska and claimed it for Russia during the 18th century. Although most Russian colonists left after the United States bought the land in 1867, a handful stayed and preserved the Russian language in this region to this day, although only a few elderly speakers of this unique dialect are left. In Nikolaevsk, Alaska , Russian
16884-482: 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. Actual aircraft followed
17018-421: Was fluent in Russian in 2006, and 19% used it as the main language with family, friends, or at work. According to the 2014 Moldovan census , Russians accounted for 4.1% of Moldova's population, 9.4% of the population declared Russian as their native language, and 14.5% said they usually spoke Russian. According to the 2010 census in Russia , Russian language skills were indicated by 138 million people (99.4% of
17152-477: 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
17286-405: 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. A convertible passenger cargo version; only one was built. The Advanced version of
17420-466: Was operating the four-engined Boeing 707 and Boeing 720 , requested a twin-engined aircraft for efficiency. 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 ). Eventually, the three airlines agreed on a trijet design for
17554-442: 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
17688-402: Was the sixth-most used language on the top 1,000 sites, behind English, Chinese, French, German, and Japanese. Despite leveling after 1900, especially in matters of vocabulary and phonetics, a number of dialects still exist in Russia. Some linguists divide the dialects of Russian into two primary regional groupings, "Northern" and "Southern", with Moscow lying on the zone of transition between
17822-427: Was to have a three-person flight crew – captain , first officer , and flight engineer – as opposed to a four- or five-person crew, as on other Soviet airliners. A fourth crew member, a navigator , was soon found to be still needed, and a seat was added on production aircraft, although that workstation was compromised due to the limitations of the original design. Navigators are no longer trained, and this profession
17956-399: Was widely used in the extreme Arctic conditions of Russia's northern/eastern regions, where other airliners were unable to operate. Originally designed for a 45,000-hour service life (18,000 cycles), but capable of 80,000 hours with upgrades, it was expected to continue in service until 2016, although noise regulations have restricted flights to Western Europe and other regions.
