'Soaring Phoenix ' is a 78–90 seat regional jet manufactured by the Chinese state-owned aerospace company Comac . Development of the ARJ21 began in March 2002, led by the state-owned ACAC consortium . The first prototype was rolled out on 21 December 2007, and made its maiden flight on 28 November 2008 from Shanghai. It received its CAAC Type Certification on 30 December 2014 and
172-547: A family . Investigation of the historical relationships among the varieties of Chinese is ongoing. Currently, most classifications posit 7 to 13 main regional groups based on phonetic developments from Middle Chinese , of which the most spoken by far is Mandarin with 66%, or around 800 million speakers, followed by Min (75 million, e.g. Southern Min ), Wu (74 million, e.g. Shanghainese ), and Yue (68 million, e.g. Cantonese ). These branches are unintelligible to each other, and many of their subgroups are unintelligible with
258-469: A nucleus that has a vowel (which can be a monophthong , diphthong , or even a triphthong in certain varieties), preceded by an onset (a single consonant , or consonant + glide ; a zero onset is also possible), and followed (optionally) by a coda consonant; a syllable also carries a tone . There are some instances where a vowel is not used as a nucleus. An example of this is in Cantonese, where
344-457: A subject–verb–object word order , and like many other languages of East Asia, makes frequent use of the topic–comment construction to form sentences. Chinese also has an extensive system of classifiers and measure words , another trait shared with neighboring languages such as Japanese and Korean. Other notable grammatical features common to all the spoken varieties of Chinese include the use of serial verb construction , pronoun dropping , and
430-455: A Chinese character is the morpheme, as characters represent the smallest grammatical units with individual meanings in the Chinese language. Estimates of the total number of Chinese words and lexicalized phrases vary greatly. The Hanyu Da Zidian , a compendium of Chinese characters, includes 54,678 head entries for characters, including oracle bone versions. The Zhonghua Zihai (1994) contains 85,568 head entries for character definitions and
516-599: A Shanghai resident may speak both Standard Chinese and Shanghainese ; if they grew up elsewhere, they are also likely fluent in the dialect of their home region. In addition to Standard Chinese, a majority of Taiwanese people also speak Taiwanese Hokkien (also called 台語 ; 'Taiwanese' ), Hakka , or an Austronesian language . A speaker in Taiwan may mix pronunciations and vocabulary from Standard Chinese and other languages of Taiwan in everyday speech. In part due to traditional cultural ties with Guangdong , Cantonese
602-462: A central variety (i.e. prestige variety, such as Standard Mandarin), as the issue requires some careful handling when mutual intelligibility is inconsistent with language identity. The Chinese government's official Chinese designation for the major branches of Chinese is 方言 ; fāngyán ; 'regional speech', whereas the more closely related varieties within these are called 地点方言 ; 地點方言 ; dìdiǎn fāngyán ; 'local speech'. Because of

The royal courts of the Ming and early Qing dynasties operated using a koiné language known as Guanhua , based on the Nanjing dialect of Mandarin. Standard Chinese is an official language of both the People's Republic of China and the Republic of China (Taiwan), one of the four official languages of Singapore , and one of
774-714: A corresponding increase in the number of homophones . As an example, the small Langenscheidt Pocket Chinese Dictionary lists six words that are commonly pronounced as shí in Standard Chinese: In modern spoken Mandarin, however, tremendous ambiguity would result if all of these words could be used as-is. The 20th century Yuen Ren Chao poem Lion-Eating Poet in the Stone Den exploits this, consisting of 92 characters all pronounced shi . As such, most of these words have been replaced in speech, if not in writing, with less ambiguous disyllabic compounds. Only

The aircraft completed a long-distance test flight on 15 July 2009, flying from Shanghai to Xi'an in 2 hours 19 minutes, over a distance of 1,300 km. The second ARJ21 (serial number 102) completed the same test flight route on 24 August 2009. The third aircraft (serial number 103) similarly completed its first test flight on 12 September 2009. The fourth aircraft (CN 104) flew by November 2010. By August 2011, static, flutter and crosswind flight tests had been completed. The ARJ21

When the United States was shocked into World War II with the Pearl Harbor attack , the airport became known as " Shwangliu Airfield " as it was later used by the United States Army Air Forces Fourteenth Air Force as part of
1204-542: A secure reconstruction of Proto-Sino-Tibetan, the higher-level structure of the family remains unclear. A top-level branching into Chinese and Tibeto-Burman languages is often assumed, but has not been convincingly demonstrated. The first written records appeared over 3,000 years ago during the Shang dynasty . As the language evolved over this period, the various local varieties became mutually unintelligible. In reaction, central governments have repeatedly sought to promulgate
1290-508: A similar way to the use of Latin and Ancient Greek roots in European languages. Many new compounds, or new meanings for old phrases, were created in the late 19th and early 20th centuries to name Western concepts and artifacts. These coinages, written in shared Chinese characters, have then been borrowed freely between languages. They have even been accepted into Chinese, a language usually resistant to loanwords, because their foreign origin

The next attested stage came from inscriptions on bronze artifacts dating to the Western Zhou period (1046–771 BCE), the Classic of Poetry and portions of the Book of Documents and I Ching . Scholars have attempted to reconstruct
1462-575: A variety of Yue from a small coastal area around Taishan, Guangdong . In parts of South China, the dialect of a major city may be only marginally intelligible to its neighbors. For example, Wuzhou and Taishan are located approximately 260 km (160 mi) and 190 km (120 mi) away from Guangzhou respectively, but the Yue variety spoken in Wuzhou is more similar to the Guangzhou dialect than
1548-602: Is Taishanese. Wuzhou is located directly upstream from Guangzhou on the Pearl River , whereas Taishan is to Guangzhou's southwest, with the two cities separated by several river valleys. In parts of Fujian , the speech of some neighbouring counties or villages is mutually unintelligible. Local varieties of Chinese are conventionally classified into seven dialect groups, largely based on the different evolution of Middle Chinese voiced initials: Proportions of first-language speakers The classification of Li Rong , which

The governments of both China and Taiwan intend for speakers of all Chinese speech varieties to use it as a common language of communication. Therefore, it is used in government agencies, in the media, and as a language of instruction in schools. Diglossia is common among Chinese speakers. For example,

2064-603: Is often described as a 'monosyllabic' language. However, this is only partially correct. It is largely accurate when describing Old and Middle Chinese; in Classical Chinese, around 90% of words consist of a single character that corresponds one-to-one with a morpheme , the smallest unit of meaning in a language. In modern varieties, it usually remains the case that morphemes are monosyllabic—in contrast, English has many multi-syllable morphemes, both bound and free , such as 'seven', 'elephant', 'para-' and '-able'. Some of

Built in 1938 and expanded for eight times, it is one of the oldest airports in China. The airport became the third-busiest airport in the world in 2020. Located about 16 kilometers (10 mi) southwest of downtown Chengdu to the north of Shuangliu , Chengdu Shuangliu Airport
2236-445: Is only about an eighth as many as English. All varieties of spoken Chinese use tones to distinguish words. A few dialects of north China may have as few as three tones, while some dialects in south China have up to 6 or 12 tones, depending on how one counts. One exception from this is Shanghainese which has reduced the set of tones to a two-toned pitch accent system much like modern Japanese. A very common example used to illustrate

China Southwest Airlines once had its headquarters on the airport property. It costs about RMB 60 Yuan from Chengdu Shuangliu International Airport to the city centre of Chengdu. Passengers can take the CRH train at Shuangliu Airport railway station to Chengdu South railway station and Chengdu East railway station ; single tickets are about ¥11 (US$ 1.5). The CRH trains at Shuangliu Airport railway station are also bound for Mianyang, Deyang, Meishan Dong (East), Leshan railway and Emeishan railway stations. Two stations on Line 10 of

As a result of its historical colonization by France, Vietnamese now uses
5074-455: The more conservative modern varieties, usually found in the south, have largely monosyllabic words , especially with basic vocabulary. However, most nouns, adjectives, and verbs in modern Mandarin are disyllabic. A significant cause of this is phonetic erosion : sound changes over time have steadily reduced the number of possible syllables in the language's inventory. In modern Mandarin, there are only around 1,200 possible syllables, including

However, calling major Chinese branches "languages" would also be wrong under the same criterion, since a branch such as Wu, itself contains many mutually unintelligible varieties, and could not be properly called a single language. There are also viewpoints pointing out that linguists often ignore mutual intelligibility when varieties share intelligibility with

There are, however, transitional areas where varieties from different branches share enough features for some limited intelligibility, including New Xiang with Southwestern Mandarin , Xuanzhou Wu Chinese with Lower Yangtze Mandarin , Jin with Central Plains Mandarin and certain divergent dialects of Hakka with Gan . All varieties of Chinese are tonal at least to some degree, and are largely analytic . The earliest attested written Chinese consists of

Until the late 20th century, Chinese emigrants to Southeast Asia and North America came from southeast coastal areas, where Min, Hakka, and Yue dialects were spoken. Specifically, most Chinese immigrants to North America until the mid-20th century spoke Taishanese ,

The entire Chinese character corpus since antiquity comprises well over 50,000 characters, of which only roughly 10,000 are in use and only about 3,000 are frequently used in Chinese media and newspapers. However, Chinese characters should not be confused with Chinese words. Because most Chinese words are made up of two or more characters, there are many more Chinese words than characters.

Route-proving started on October 29, 2014, and AC105 made 83 flights between ten airports in Chengdu, Guiyang, Guilin, Haikou, Fuzhou, Zhoushan, Tianjin, Shijiazhuang, Yinchuan and Xianyang. The cumulative flight time
6020-517: The six official languages of the United Nations . Standard Chinese is based on the Beijing dialect of Mandarin and was first officially adopted in the 1930s. The language is written primarily using a logography of Chinese characters , largely shared by readers who may otherwise speak mutually unintelligible varieties. Since the 1950s, the use of simplified characters has been promoted by
6106-561: The slightly later Menggu Ziyun , this dictionary describes a language with many of the features characteristic of modern Mandarin dialects. Up to the early 20th century, most Chinese people only spoke their local variety. Thus, as a practical measure, officials of the Ming and Qing dynasties carried out the administration of the empire using a common language based on Mandarin varieties , known as 官话 ; 官話 ; Guānhuà ; 'language of officials'. For most of this period, this language
6192-623: The tonal distinctions, compared with about 5,000 in Vietnamese (still a largely monosyllabic language), and over 8,000 in English. Most modern varieties tend to form new words through polysyllabic compounds . In some cases, monosyllabic words have become disyllabic formed from different characters without the use of compounding, as in 窟窿 ; kūlong from 孔 ; kǒng ; this is especially common in Jin varieties. This phonological collapse has led to
6278-547: The traditional Western notion of a word. A Chinese cí can consist of more than one character–morpheme, usually two, but there can be three or more. Examples of Chinese words of more than two syllables include 汉堡包 ; 漢堡包 ; hànbǎobāo ; 'hamburger', 守门员 ; 守門員 ; shǒuményuán ; 'goalkeeper', and 电子邮件 ; 電子郵件 ; diànzǐyóujiàn ; 'e-mail'. All varieties of modern Chinese are analytic languages : they depend on syntax (word order and sentence structure), rather than inflectional morphology (changes in
6364-529: The two web-based sources cited in the footnotes. Also note that the numbers listed are for the initial annual deliveries to (non- COMAC ) commercial operators and do not necessarily reflect the number of airframes currently operated by each listed operator; as a result, the total number delivered may exceed the total number of airframes cited in the original contracts. (+Options) Reported Orders An Indonesian airline will fly with its entire fleet consisting of 60 ARJ21 aircraft, although as of now that airline
6450-522: The type certification and testing program was completed in December 2022 and the type certified by the CAAC on 1 January, 2023. The first two ARJ21 converted freighters (B-3329 and B-3388) were delivered to customers on 30 October 2023. The two airframes were initially delivered to Chengdu Airlines in 2018 in the passenger configuration and were subsequently withdrawn for the P2F program in 2021. Airframe B-3329
6536-512: The use of tones in Chinese is the application of the four tones of Standard Chinese, along with the neutral tone, to the syllable ma . The tones are exemplified by the following five Chinese words: In contrast, Standard Cantonese has six tones. Historically, finals that end in a stop consonant were considered to be " checked tones " and thus counted separately for a total of nine tones. However, they are considered to be duplicates in modern linguistics and are no longer counted as such: Chinese
6622-452: The words in newspapers, and 60% of the words in science magazines. Vietnam, Korea, and Japan each developed writing systems for their own languages, initially based on Chinese characters , but later replaced with the hangul alphabet for Korean and supplemented with kana syllabaries for Japanese, while Vietnamese continued to be written with the complex chữ Nôm script. However, these were limited to popular literature until
6708-517: The written language used throughout China changed comparatively little, crystallizing into a prestige form known as Classical or Literary Chinese . Literature written distinctly in the Classical form began to emerge during the Spring and Autumn period . Its use in writing remained nearly universal until the late 19th century, culminating with the widespread adoption of written vernacular Chinese with
6794-545: Was 173 hours and 55 minutes. By November 2014, AC104 had completed 711 flights in 1,442 hours and 23 minutes. Certification tests included stall, high-speed, noise and simulated and natural icing. AC105 returned to Yanliang airport on December 16, 2014, from Xi'an Xianyang International Airport after the last function and reliability flight. This completed the testing for the ARJ21-700 airworthiness certificate. The ARJ21-700 received its Type Certification under Chapter 25 of
6880-453: Was a koiné based on dialects spoken in the Nanjing area, though not identical to any single dialect. By the middle of the 19th century, the Beijing dialect had become dominant and was essential for any business with the imperial court. In the 1930s, a standard national language ( 国语 ; 國語 ; Guóyǔ ), was adopted. After much dispute between proponents of northern and southern dialects and an abortive attempt at an artificial pronunciation,
6966-457: Was approved by the CAAC. During the summer schedule period of 2016, i.e. until October 29, 2016, the ARJ21-700 was scheduled to operate three weekly rotations between Chengdu and Shanghai Hongqiao. 85 flight segments were operated by ARJ21 (81 by B-3321, four by B-3322). In June 2018 an ARJ21-700+ was proposed for 2021 with weight and drag reductions. Subsequently, a -900 stretch version was designed to accommodate 115 all-economy seats, similar to
7052-457: Was conducted on flight area and navigation area from 1994 to 2001. The runway was extended to 3,600 metres (11,811 ft) with Class 4E rating, allowing for larger jumbo jets including the Boeing 747-400 . The newly built terminal building was incorporated with a three-parallel-porch design, accommodating an hourly capacity of 3,500 passengers during rush hours, while the previous terminal building
7138-493: Was handed over to YTO Cargo Airlines which intends to operate the type on short-haul international routes while airframe B-3388 was delivered to Air Central (based in Zhengzhou , China) for flights on domestic routes. The converted freighters have a maximum payload capacity of 10 tonnes and a range of about 1500 nautical miles (2780 km). In early July 2017, the CAAC certified the ARJ21 for mass production. On 6 March 2020,
7224-485: Was hidden by their written form. Often different compounds for the same concept were in circulation for some time before a winner emerged, and sometimes the final choice differed between countries. The proportion of vocabulary of Chinese origin thus tends to be greater in technical, abstract, or formal language. For example, in Japan, Sino-Japanese words account for about 35% of the words in entertainment magazines, over half
7310-405: Was introduced on 28 June 2016 by Chengdu Airlines . The ACAC consortium was reorganized in 2009 as part of Comac and the jet was rebranded as the C909 in November 2024. It features a 25° swept , supercritical wing designed by Antonov and twin rear-mounted General Electric CF34 engines. 100 airframes had been delivered by the end of 2022. The development of the ARJ21 (Advanced Regional Jet)
7396-588: Was only designated for regional flights within Sichuan and Chongqing . The airport is now an international civil airport with flights to more than 50 international destinations and over 170 domestic airports, and is a hub for Chengdu Airlines , Air China and Sichuan Airlines . It is linked to downtown Chengdu by the Airport Expressway, the Chengdu–Mianyang–Leshan intercity railway and
