. On July 27, the reporter learned from China Electronics Technology avionics Co., Ltd. (hereinafter referred to as cetca) in Chengdu that Kunlong went to sea, and the “made in Sichuan” communication and navigation system helped the successful first flight of ag600 aircraft on the sea. At 10:18 a.m. on July 26,

and

successfully made its first flight at sea in Qingdao, accompanied by bright sea breeze and surging waves. This is another highlight time for ag600 aircraft after the first flight on land on December 24, 2017 and the first flight on water on October 20, 2018.

China Electronics Technology avionics Co., Ltd. (hereinafter referred to as cetca Avionics) in Chengdu has taken the lead in the development of ag600 communication and navigation system.

and

are ag600 communication and navigation systems developed by cetca, which are equivalent to “eyes”, “ears” and “mouths” of aircraft.

,

and “eyes” refer to aircraft navigation system, which provides position and navigation information for aircraft, mainly including GPS positioning and navigation, radio station ranging (DME), radio station lateral (VOR), airborne direction finder (ADF) and instrument landing (ILS / MB).

,

, ,

,

, “ear” and “mouth” refer to the communication system of aircraft, which mainly realizes VHF voice communication between aircraft and ground station, between aircraft and aircraft, between aircraft and ground tower, and between different stations in aircraft.

the core equipment of

,

project team of cetca ag600 project is independently researched and developed. Mature shelf products are purchased for peripheral equipment. Ag600 communication and navigation system takes a new R & D mode. Ag600 aircraft communication and navigation system is the first large civil aircraft communication and navigation system designed and developed in China. Cetca is responsible for system design and integrated development, and develops system level core avionics equipment with domestic suppliers, while mature shelf products are purchased for peripheral products. This mode not only ensures the leading role of cetca in core equipment development and system integration, but also makes full use of the advantages of mature shelf products. The success of the first flight of

and

at sea is a significant milestone in the development of ag600. From the first flight on land on December 24, 2017, the first flight on water on October 20, 2018, and then the first flight at sea on July 26, 2020, cetca’s radio communication and navigation system field test and flight test engineering team organized and guaranteed the whole process of ag600 aircraft from the aspects of Engineering technology, quality airworthiness, integrated management, security and confidentiality, ensuring kunlongcheng The work “goes to sea”. The follow-up scientific research flight test is also under active preparation and promotion.

ag600, also known as Kunlong 600, together with yun-20 and C919, is called “three swordsmen of China’s large aircraft”. It is a large-scale amphibious aircraft for fire fighting / water rescue developed by China, and is also the largest amphibious aircraft under research in the world.

The development of

aircraft responds to the requirements of the state on the development of advanced aviation special equipment and innovation of emergency rescue system, meets the urgent needs of forest fire fighting and water rescue in China, and forms a large amphibious aircraft design and development technology system with independent intellectual property rights, which lays a solid technical foundation for the large-scale and seriation of amphibious aircraft. Ag600 aircraft applies for type certificate (TC) according to ccar-25-r4 standard, and develops according to relevant airworthiness regulations.
