Ako moze jedno pojasnjenje u vezi ovog naziva Airguard .Da li se taj naziv odnosi na J-7 uopsteno ili samo za verziju F-7M ?
Kineski izvor navodi taj naziv samo za F-7M
 http://www.sinodefence.com/airforce/fighter/j7.asp
Evo ponesto o samoj verziji
Citat:F-7M Airguard Improved J-7II variant for export with western avionics, with British GEC-Marconi as the prime contractor. Program initiated in 1978 and took six years to complete, after 10 rounds of negotiation. Western avionics includes:
British Type 226 Skyranger radar: Ranging radar that weighs 41 kg with a range of 15 km.
British Type 956 HUDAWAC: This HUD has a built-in weapon aiming computer, hence the name Head-Up Display And Weapon Aiming Computer.
British Type 50-048-02 digitized air data computer
British Type 2032 camera gun, which is linked to HUD with capability to interchange rolls of film while airborne. Each roll of film lasts more than 2 minutes
American converter that is over 30% more efficient in comparison to the original Chinese converter.
American Type 0101-HRA/2 radar altimeter with range increased to 1.5 km in comparison to the original 0.6 km of the Chinese radar altimeter it had replaced.
British AD-3400 secured radio with range in excess of 400 km at 1.2 km altitude.
Other improvement includes domestic newly designed CW-1002 air data sensor developed in conjunction with the western avionics, and WP-7B/WP-7BM engine.
A totally different wing enabled the take-off and landing distance to be reduced by 20%, while increasing the aerodynamic performance in dogfights. According to customers' claims, F-7M is nearly 40% more effective than MiG-21 in terms of overall performance. It can use French R550 Magic and PL-7 Air-to-air missiles. It was sold to Myanmar, Egypt and Bangladesh in 1980s.
Pakistan contribution: Although Pakistan did not purchase any F-7M and later returned all 20 F-7M's to China after evaluation to require China to provide a better fighter (which eventually resulted in F-7MP/P), Pakistan did provide important support for F-7M program, including:
In the last quarter of 1982, test flights revealed that the radar was plagued by the problem of picking up ground clutter. China did not have any western radar assisted air-to-ground attack experience, and had no idea of conducting the necessary flight tests specifically designed for the western avionics to solve the problem. Pakistani Air Force provided pilots (including F-16 pilots) to China to perform these tests and helped in solving this problem.
Chinese 630th Institute responsible for F-7M program lacked the facility and experience to conduct live round weapon tests with advanced western avionics, and it also lacked the capability to conduct mocked air combat with western aircraft. Therefore from June, 1984 to September, 1984, two F-7Ms were sent to Pakistan to conduct such tests. Pakistan Air Force once again provided F-16 pilots to help to complete the tests, with the Chinese team in Pakistan led by Mr. Chen Baoqi (陈宝琦) of the Chinese Aviation Ministry and Mr Xie Anqing (谢安卿) of Chengdu Aircraft Co.
Kad smo kod naziva da pomenem i F-7P Skybolt
Citat:F-7P Newly-built Skybolt for the Pakistani Air Force (PAF). A total of 60 were built. Starting with this model, F-7s in the Pakistani service began to be upgraded with the Italian FIAR Grifo-Mk-II radar license assembled by the ISO - 9002 certified Kamra avionics, Electronics and Radar Factory of the Pakistan Aeronautical Complex (PAC).

Malo i o kineskinjama koje lete na J-7
 
 
Citat:Women J-7 pilots.
Citat:PLA Air Force trains 328 female pilots
BEIJING - A total of 328 female pilots have been trained by the People's Liberation Army (PLA) Air Force over the past six decades, according to figures disclosed at a ceremony held Thursday to mark the 60th anniversary of the debut flight of Chinese women pilots.
The PLA Air Force has recruited a total of nine groups of female pilot trainees over the past 60 years, and eight of these groups have already graduated, figures show.
Women pilots joined the flight mission of the PLA Air Force for the first time on March 8, 1952, when a group of them flew planes over the Tian'anmen Square in Beijing as a flight show.
Since then, they have successfully completed numerous key missions in chartered flight, disaster relief, research-oriented trial flight, and afforestation by airplane sowing, and they have flown in the National Day parade air show.
Xu Qiliang, a member of the Central Military Commission and commander of the PLA Air Force, attended the ceremony.

Postoje informacije da je tako. A takodje i da taj naziv nije prihvacen kao i da nije prihvacen naziv Skybolt za F-7P.
