Introduction of Linzhi Milin Airport?

Linzhi Milin Airport (IATA code: LZY, ICAO code: ZUNZ) started construction in 2003 10, and was officially opened to traffic at the end of September 2006 1, with an investment of 780 million yuan. It is one of the key projects in Xizang Autonomous Region, with the designed annual passenger capacity of120,000.

Linzhi Airport is located in Yarlung Zangbo River Valley, Milin County, Linzhi City, 50 kilometers away from Bayi Town, Bayi District, Linzhi City, with an altitude of 2,949 meters, which is lower than Qamdo Bangda Airport with an altitude of 4,334 meters and Lhasa Gongga International Airport with an altitude of 3,570 meters. Its altitude ranks 12 among domestic civil airports.

Linzhi Milin Airport is a civil aviation airport with the lowest altitude in Tibet, the first flight difficulty in China and the third flight difficulty in Tibet. The airport is 2949 meters above sea level and belongs to plateau airport.

20 16 Linzhi airport was awarded the "Best Regional Tourism Airport" in 20 15 by china tourism association Civil Aviation Tourism Professional Committee, making it one of the five airports in China.

Airport characteristics

Environmental characteristics

Linzhi Milin Airport is located in the valley on the south bank of Yarlung Zangbo River, belonging to plateau airport. Due to the special terrain and changeable meteorological conditions, the flight conditions, clearance environment and navigation station layout of Linzhi Milin Airport are very difficult. Therefore, Linzhi Airport in China is one of the airports with the most complicated clearance conditions, meteorological conditions, flight environment and navigation station layout in the world.

The lowest altitude is the hardest.

Linzhi Airport started construction in June 2003, with a joint investment of 780 million yuan by the National Development and Reform Commission of China and the Civil Aviation Administration of China. It is one of the key projects in Xizang Autonomous Region, with the designed annual passenger throughput of120,000, and it is positioned as a regional tourist airport. On April 28th, 2006, the airport was completed and passed the acceptance of the acceptance working group. The flight zone of Linzhi Airport is 4C, the runway is 3km long and 60m wide (including the shoulder), and the largest take-off and landing model is Boeing 757. Two aircraft of this type can be parked on the tarmac at the same time.

Linzhi Milin Airport is 2949 meters above sea level, lower than Changdu Bangda Airport of 4334 meters and Lhasa Gongga Airport of 3570 meters, ranking fifth among domestic civil airports. However, the airport is located in the Yarlung Zangbo River valley in the southeast of the Qinghai-Tibet Plateau, surrounded by more than 4,000 meters of mountains and mountains shrouded in fog all the year round. The daily wind speed increases from 14 to 18 to 27 m/s, which is much higher than the airworthiness standard of Boeing 757. Aircraft can only take off and land in the morning, and according to meteorological data, the airworthiness time of the airport is only 65438. Because the route through the canyon is narrow and tortuous, which exceeds the normal flight standard, the aircraft's near-ground automatic alarm device may be triggered at any time during the descent approach. At the same time, due to the complex terrain, the signals sent by navigation equipment will be severely shielded and interfered, and the flight airspace range is very limited. Moreover, the Mirin navigation station on the west side of the airport is only 1 1.2 kilometers away from the actual control line between China and India, which makes the crew's technical level and psychological quality face a severe test, requiring them to make every turn in the air and every flight. Linzhi Airport is the airport with the most complicated clearance environment, meteorological conditions, navigation station layout and flight procedures in China, and it is the most difficult to ensure the take-off and landing of aircraft and the punctuality of flights. It is also one of the most difficult airports in the world.

Airport facilities

Navigation facilities

In order to ensure the flight safety of Linzhi Airport, a unique plateau airport, the navigation equipment installed in the airport includes two sets of instrument navigation systems, one set of instrument landing system, one set of VHF omnidirectional beacon and two sets of precision approach channel indicators.

In order to ensure the safe flight of aircraft in the river valley, the airport has established navigation stations at every turn of the route;

At the same time, the airport also installed a wind profile radar to monitor the wind speed and direction in the surrounding areas. Only Linzhi Airport and Jiuzhaigou Airport use this equipment in China.

Lightning protection facilities

Linzhi City, located in the southeast of Tibet, is one of the lightning disaster-prone areas in China, with an average annual thunderstorm day of over 47.5 days. Linzhi Airport is located in the Yarlung Zangbo River Valley in Milin County, surrounded by empty space and without any other high-rise buildings. Special geographical and environmental factors make lightning accidents very easy to happen. Lightning protection facilities have been installed in all airport building facilities.

Building facilities

Terminal area and navigation station engineering: terminal building engineering, air traffic control building and tower, navigation station engineering, civil air defense engineering, comprehensive business building, special garage, airport staff duty room, fire station, communication navigation, meteorological navigation aid lighting installation engineering (including flight area greening).
