112-629: The People's Liberation Army Air Force (PLAAF) has had a requirement for a high-altitude medium utility helicopter that can operate in the mountainous regions in China since the 1980s. In 1984, the PLAAF acquired 24 Sikorsky S-70 C-2s with enhanced General Electric T700-701A engines from the US government. China was unable to purchase more Sikorsky aircraft following the fallout from the 1989 Tiananmen Square protests that resulted in an EU and US arms embargo. This led to

224-513: A 2015 Pentagon report, PLAAF had approximately 600 modern aircraft and phased out more outdated platforms. The percentage of fourth-generation fighters raised from 30 percent in 2010 to 50 percent in 2015, projecting a majority fourth-generation force structure in the near future. The PLAAF also focused on developing long-range strike options with improved bomber platforms based on Xian H-6K , long-range cruise missiles, as well as fielding more multirole aircraft such as Shenyang J-16 .

MRO firms are responsible for this process, thoroughly checking and documenting all components' repairs while tracking mechanical, propulsion, and electronic parts. Aviation regulators oversee maintenance practices in the country of aircraft registration, manufacture, or current location. All aircraft maintenance activities must adhere to international regulations that mandate standards. An aviation accident

672-429: A combined arms training base to conduct multi-force joint operations. In 2003, PLAAF began structural reforms and reduced the number of personnel by 200,000 (85% were officials), freeing up resources for the force overhaul. The leadership was consolidated to become more operationally efficient. Three dedicated training bases were established to provide research, testing, training, and combat support. In 2004, PLAAF released

784-456: A feat made possible by their invention of three-axis control and in-house development of an engine with a sufficient power-to-weight ratio . Only a decade later, at the start of World War I , heavier-than-air powered aircraft had become practical for reconnaissance, artillery spotting, and even attacks against ground positions. Aircraft began to transport people and cargo as designs grew larger and more reliable. The Wright brothers took aloft

2240-752: Is especially important for aircraft flying under instrument flight rules (IFR), when they may be in weather conditions that do not allow the pilots to see other aircraft. However, in very high-traffic areas, especially near major airports, aircraft flying under visual flight rules (VFR) are also required to follow instructions from ATC. In addition to separation from other aircraft, ATC may provide weather advisories, terrain separation, navigation assistance, and other services to pilots, depending on their workload. ATC do not control all flights. The majority of VFR (Visual Flight Rules) flights in North America are not required to contact ATC (unless they are passing through

2352-490: Is missing or is completely inaccessible. An accident in which the damage to the aircraft is such that it must be written off, or in which the plane is destroyed, is called a hull loss accident . The first fatal aviation accident occurred in a Wright Model A aircraft at Fort Myer, Virginia, US , on September 17, 1908, resulting in injury to the pilot, Orville Wright , and death of the passenger, Signal Corps Lieutenant Thomas Selfridge .

7840-481: The force reform concept "Strategic Air Force", aiming to reconstruct the PLAAF into an integrated fighting force capable of both offensive and defensive operations in air and space. The 2004 reform included changes in doctrine, equipment, training, education, organizational structure, and strategic thinking. By 2005, PLAAF was in the process of modernizing force composition by retiring obsolete aircraft. The antiquated Shenyang J-6 fighters were completely phased out of

7952-673: The form of Xian Y-20 and WS-20 engines. In 2021, PLAAF announced the force had achieved the status of "Strategic Air Force". Though the self-claimed designation wasn't universally agreed upon, many analysts acknowledged the rapid modernization progress. According to the Air University assessment in 2022, PLAAF was adjudged a strategic air force with the capabilities of long-distance power projection , maintaining combat readiness, and conducting global operations to protect Chinese interests. In 2023, PLAAF planned to decommission all older Chengdu J-7 and Shenyang J-8 platforms, which completed

8064-448: The further induction of platforms such as Sukhoi Su-30 and S-300 PMU-1 . At the same time, PLAAF leadership advocated for more active roles in the Chinese military but was sidelined by the PLA headquarters due to concerns over political reliability and a general lack of capabilities. PLAAF continued persuasive efforts, and their plans were eventually endorsed by the PLA leadership in the late 1990s and early 2000s. In 1999, PLAAF set up

8176-406: The introduction of composite materials to make small aircraft lighter and faster. Ultralight and homebuilt aircraft have also become increasingly popular for recreational use, since in most countries that allow private aviation, they are much less expensive and less heavily regulated than certified aircraft. Simple balloons were used as surveillance aircraft as early as the 18th century. Over

8288-529: The late 1980s and early 1990s, PLAAF still remained a large yet antiqued force. As of 1995, the air force consisted of approximately 4,500 combat aircraft based on the 1950s and 1960s technologies, which were approaching the end of their service life. The overall force strategy is defensive, with the primary objectives limited to protecting cities, airbases, economic and industrial centers, and important institutions and facilities. The air fleet continued to shrink, with RAND Corporation predicting PLAAF being halved by

8400-598: The late 1980s. After critical assessments, the 1985 reform led to force reduction, reorganization, and streamlining. Before the 1985 reorganization, the Air Force reportedly had four branches: air defense , ground attack , bombing , and independent air regiments. In peacetime the Air Force Directorate, under the supervision of the PLA General Staff Department , controlled the Air Force through headquarters located with, or in communication with, each of

8512-504: The limited range of capabilities and political considerations. PLAAF was used as a deterrence due to the political culture at the time. The Chinese leadership, in many instances, would cancel offensive bombing missions to prevent escalation, affecting the decision-making autonomy of the PLAAF. In 1960, Soviet engineers and advisors left China due to the Sino-Soviet split ; although the Soviet Union granted licensed rights to MiG-15, MiG-17, MiG-19, MiG-21, Il-28, and Tu-16, China didn't retain

8624-709: The mid-2000s, PLAAF had grown familiar with precision-guided munitions, aerial refueling, AEW&C aircraft, and networked command&control systems. Several uncertainties troubled the PLAAF leadership, including China's inability to produce advanced jet engines, the lack of bombers to conduct long-range strike missions, and the dilemma between procuring foreign designs or supporting the homegrown defense industry that could only produce less capable ones. Thus, generous resources were devoted to research and development, with every possible approach, including purchase, license, technology transfer, reverse-engineering , and intelligence gathering to absorb foreign technology and build up

8736-464: The most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout

8848-469: The new PLAAF organized its headquarters (PLAAF HQ) in Beijing and organized administrative aviation divisions for each of the PLA's six military regions, later to each be named a Military Region Air Force (MRAF). The new organization, which was not yet seen as a service separate from the army, was headed by ground force commander Liu Yalou with Xiao Hua (former ground force commander and political commissar) as

8960-493: The new middle-class market. By the 1950s, the development of civil jets grew, beginning with the de Havilland Comet , though the first widely used passenger jet was the Boeing 707 , because it was much more economical than other aircraft at that time. At the same time, turboprop propulsion started to appear for smaller commuter planes, making it possible to serve small-volume routes in a much wider range of weather conditions. Since

9072-412: The operation of aircraft, are reduced and controlled to an acceptable level. It encompasses the theory, practice, investigation, and categorization of flight failures, and the prevention of such failures through regulation, education, and training. It can also be applied in the context of campaigns that inform the public as to the safety of air travel. A maintenance, repair, and overhaul organization (MRO)

9184-466: The political turmoil, with many aircraft development programs stretched out, and the quality control in factories wasn't sustained due to disruptions caused by Red Guards . Political fallouts from the Culture Revolution could still be felt by the leadership, and recovery only began in the 1980s. PLAAF leadership recognized the importance of modern airpower and the existing weakness of the force in

9296-534: The possibility of flying machines becoming practical. Lilienthal's work led to him developing the concept of the modern wing. His flight attempts in Berlin in 1891 are seen as the beginning of human flight and the " Lilienthal Normalsegelapparat " is considered to be the first airplane in series production, making the Maschinenfabrik Otto Lilienthal in Berlin the first air plane production company in

9408-501: The purchase of 38 Ilyushin Il-76 and Ilyushin Il-78 transport/tanker aircraft. To replace the antiquated Nanchang Q-5 attacker, PLAAF introduced fighter-bomber Xi'an JH-7A with precision strike capabilities. The homegrown Chengdu J-10 platform also matured into a highly capable, multirole fighter as PLAAF continued to accumulate experience in operating modern aircraft since the 1990s. By

9520-414: The role of a multi-role naval helicopter for the People's Liberation Army Navy (PLAN) that is small enough to be interoperable across all PLAN vessels while still have a full suite of anti-submarine warfare (ASW) capabilities installed. The Z-20 has been tested carrying missiles on wing pylons. A stealth Z-20 variant has been indicated under development since 2015. One analyst said China could produce

9632-450: The same province as MRAF headquarters (MRAF HQ). From 2004, leadership of units was consolidated in MRAF HQ, with air corps and Bases downgraded to command posts that acted on behalf of MRAF HQ. From 2012 onwards, the command posts were mostly replaced by Bases that exercised command and control over units (brigades) in their AOR and conducted joint exercises. The first divisions in the 1950s

9744-494: The second-largest active combat aircraft fleet and the third-largest total aircraft fleet in the world. In 2023, the [PLANAAF] transferred the majority of its fixed-wing combat aircraft to the PLAAF, with the intent of simplifying logistics and focusing on carrier based planes. According to the International Institute for Strategic Studies , PLAAF combat pilots acquire an average of 100-150 flying hours annually. For

9856-496: The senior position, putting all service branches in the same echelon, thus ending the tradition of Army domination in PLA's command structure. A joint command structure under the newly reformed theater commands was established, improving inter-service support, command and control efficiency, and cross-service warfighting capability. In 2016, PLA established People's Liberation Army Strategic Support Force , which stripped PLAAF's responsibilities in space and information domain, leaving

9968-605: The service, and the more competent Chengdu J-7 and Shenyang J-8 platforms were partially retired with the remaining fleet upgraded with improved technologies. The number of second and third-generation aircraft was reduced to about 1,000 planes. Fighters of foreign and domestic origin with modern avionics and missiles began to enter the service more rapidly. From 2000 to 2004, PLAAF incorporated 95 home-built Shenyang J-11A with license, acquired 76 Sukhoi Su-30MKK and 24 Su-30MK2 from Russia with improved composite material, weapons, and avionics akin to Sukhoi Su-35 , and negotiated

10080-656: The seven military region headquarters. In war, control of the Air Force probably reverted to the regional commanders. In 1987 it was not clear how the reorganization and the incorporation of air support elements into the group armies affected air force organization. The largest Air Force organizational unit was the division , which consisted of 17,000 personnel in three regiments . A typical air defense regiment had three squadrons of three flights; each flight had three or four aircraft. The Air Force also had 220,000 air defense personnel who controlled about 100 surface-to-air missile sites and over 16,000 AA guns. In addition, it had

10192-448: The shortly-lived Aviation Bureau with Chang and Wang appointed as the bureau's director and political commissar, respectively. On 1 October 1949, the victorious communist forces established the People's Republic of China and, on 11 November 1949, the CMC dissolved its Aviation Section founding instead the People's Liberation Army Air Force. Initially manned by a variety of units from ground forces,

10304-481: The stealth variant relatively easily because of their access to a modified MH-60 Black Hawk tail section , recovered by Pakistani security forces after a crash during the Bin Laden raid . In May 2021, the concept model of the stealthy Z-20 variant was public revealed. The model displayed a trapezoidal airframe, a shrouded main rotor hub, and an upper-facing ventilation system located on an enlarged tail boom. The Z-20

10416-595: The technical material or machinery as the Soviet advisory withdrew. China had to reverse-engineer aircraft and missile systems to set up production lines. Internal political and economic chaos from the Cultural Revolution and the Great Leap Forward severely impacted the modernization and development of the PLAAF. The prioritization of the missile and nuclear weapon programs also removed necessary resources from

10528-972: The traditional practice of training pilot at operational units. The measure improved training efficiency and prevented distraction to the defense responsibilities of the active units. According to International Institute for Strategic Studies, PLAAF had an unprecedented military build-up between 2016 and 2022. The force successfully closed the gap with the West due to improved domestic production, introducing indigenously developed airframes, composite materials, turbofan engines, advanced avionics, and weapon systems. In six years, PLAAF incorporated over 600 fourth- and fifth-generation aircraft in more than 19 frontline combat brigades. The modern Chengdu J-10C , Shenyang J-16 , and Chengdu J-20 are all equipped with AESA radar systems, domestic WS-10 engines, standoff weapons , and long-range air-to-air missiles. PLAAF also made substantial progress with larger aircraft design and production in

10640-518: The tutelage of the more experienced Soviet Air Force . Two of the CCP's graduates, Chang Qiankun and Wang Bi, continued to serve in the Soviet Air Force for fourteen years until, in September 1938, they returned to Dihua (now Ürümqi ) as instructors. Chang and Wang would play instrumental roles in the founding of the PLAAF. In January 1941, as intensifying clashes between CCP and KMT forces ended

10752-687: The united front against invading Japanese forces , and despite having neither aircraft nor airfields, the CCP's Central Military Commission (CMC) established the Air Force Engineering School with Wang as commandant and Chang as head instructor. In May 1944, just over a year before the Japanese surrender to Allied forces , the CMC established an Aviation Section in Yan'an with Wang as its director and Chang as deputy director. Two years later in May 1946 and after

10864-513: The war as an air defense force. The main role was to support the army by achieving air superiority using fighters, radar, and ground-based weapons. This was reinforced through the 1950s and 1960s when the PLAAF's main activities were skirmishing with the Republic of China Air Force near the Taiwan Strait , and intercepting American aircraft. The PLAAF was passive in applying offensive airpower due to

10976-581: The withdrawal of Japanese troops, the CMC established the Northeast Old Aviation School in Jilin. By 1949 the Aviation Section of the CMC had 560 trained personnel (125 pilots and 435 ground support specialists), purchased 435 aircraft from the Soviet Union, acquired 115 Nationalist aircraft, and operated seven military flight schools. The first organized air unit of the People's Liberation Army

11088-670: The world and the first in Asia to field an operational stealth aircraft . Around the same time, PLAAF introduced PL-10 and PL-15 missiles to noticeably improved the PLAAF's air combat capability. By 2019, aviation researchers believed that Chinese weapon platforms have reached approximate parity with Western equivalents, and surpassed Russia in most aspects of aviation technology development and implementation. In 2019 and 2020, PLAAF began to reform its pilot curriculum and transitional training programs, inducting advanced jet trainers and active-service fighters at dedicated training academies, ending

11200-603: The world support these manufacturers, who sometimes provide only the initial design and final assembly in their own plants. The Chinese ACAC consortium has also recently entered the civil transport market with its Comac ARJ21 regional jet. Until the 1970s, most major airlines were flag carriers , sponsored by their governments and heavily protected from competition. Since then, open skies agreements have resulted in increased competition and choice for consumers, coupled with falling prices for airlines. The combination of high fuel prices, low fares, high salaries, and crises such as

11312-632: The world. The word aviation was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He originally derived the term from the verb avier (an unsuccessful neologism for "to fly"), itself derived from the Latin word avis ("bird") and the suffix -ation . There are early legends of human flight such as the stories of Icarus in Greek myth, Jamshid and Shah Kay Kāvus in Persian myth, and

11424-426: The world. Lilienthal is often referred to as either the "father of aviation" or "father of flight". Early dirigible developments included machine-powered propulsion ( Henri Giffard , 1852), rigid frames ( David Schwarz , 1896) and improved speed and maneuverability ( Alberto Santos-Dumont , 1901) There are many competing claims for the earliest powered, heavier-than-air flight. The first recorded powered flight

11536-442: The years, military aircraft have been built to meet ever increasing capability requirements. Manufacturers of military aircraft compete for contracts to supply their government's arsenal. Aircraft are selected based on factors like cost, performance, and the speed of production. Aviation safety means the state of an aviation system or organization in which risks associated with aviation activities, related to, or in direct support of

11648-466: Was carried out by Clément Ader on October 9, 1890, in his bat-winged, fully self-propelled fixed-wing aircraft , the Ader Éole . It was reportedly the first manned, powered, heavier-than-air flight of a significant distance (50 m (160 ft)) but insignificant altitude from level ground. Seven years later, on October 14, 1897, Ader's Avion III was tested without success in front of two officials from

11760-541: Was formed in 1962. Aircraft inventory of PLAAF August 1st Aerobatic Team includes the J-10 and it has previously flown the J-5 and J-7 . The Sky Wing and Red Falcon air demonstration teams, which operate Nanchang CJ-6 and Hongdu JL-8 respectively, were established in 2011. The People's Liberation Army Air Force operates a large and varied fleet of some 4,000 aircraft, of which around 2,566 are combat aircraft (fighter, attack, and bombers). According to FlightGlobal , China has

11872-569: Was formed in July 1949 at Beijing Nanyuan Airport (built and first operated under the Qing Dynasty ) and operated American P-51 Mustangs , PT-19s, and British DH.98 Mosquitos . The squadron had acquired the Western-made aircraft once donated to the KMT for use against the Japanese, through a series of airfield captures and nationalist defections. In March 1949, the CMC elevated its Aviation Section to

11984-415: Was highly flammable and allowed static electricity to build up in the airship. Changes to the coating formulation reduced the risk of further Hindenburg type accidents. Although there have been periodic initiatives to revive their use, airships have seen only niche application since that time. There had been previous airship accidents that were more fatal, for instance, a British R38 on 23 August 1921, but

12096-673: Was made in aircraft design with the incorporation of Western avionics into the Chengdu J-7 and Shenyang J-8 , the development of refueling capabilities for the B-6D bomber and the A-5 attack fighter, increased aircraft all-weather capabilities, and the production of the HQ-2J high-altitude surface-to-air missile and the C-601 air-to-ship missile. Although the PLAAF received significant support from Western nations in

12208-424: Was organized into a HQ and two or three regiments. In 1953, this was standardized to three regiments per division, including one training regiment. Regiments had three or four flight groups, each in turn made of three or four squadrons. Between 1964 and 1970, regiments were called groups. In the late 1980s, operational squadrons lost their training regiments. By 2010, many divisions had only two regiments. In 2019,

12320-456: Was projected to become one of the most capable air forces in 2020. PLAAF improved capabilities in several areas, including fighters, advanced missiles, early warning systems, and air defense systems; the force also started major reforms in training and doctrines. PLAAF leadership realized the force was insufficient to counter US intervention in the Taiwan strait confrontations, thus invested heavily in

12432-545: Was the Douglas DC-3 , which became the first airliner to be profitable carrying passengers exclusively, starting the modern era of passenger airline service. By the beginning of World War II, many towns and cities had built airports, and there were numerous qualified pilots available. During World War II one of the first jet engines was developed by Hans con Ohain, and accomplished the world's first jet-powered flight in 1939. The war brought many innovations to aviation, including

12544-810: Was the Tenerife airport disaster on March 27, 1977, when 583 people died when two Boeing 747 jumbo jets, operated by Pan Am and KLM collided on a runway in Los Rodeos airport, now known as Tenerife North. An aviation incident is defined as an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operations. Air traffic control (ATC) involves communication with aircraft to help maintain separation – that is, they ensure that aircraft are sufficiently far enough apart horizontally or vertically for no risk of collision. Controllers may co-ordinate position reports provided by pilots, or in high traffic areas (such as
