An air corridor is an air flight passage with a width of 5km on both sides of the two-point line. It is used for aircraft to fly between points in the corridor, with a minimum of 4km. Make the aircraft fly in strict accordance with the corridor to avoid the aircraft entering the restricted area outside the corridor.

Beijing, Shanghai, Guangzhou, Chengdu, Xi'an, Shenyang, Wuhan and other big cities have air corridors. When a plane goes to the airports of these big cities, it is not allowed to fly over the city at will and directly go to the airport. It must first fly to the designated place (i.e. the corridor entrance), then follow the air corridor, and then fly to the airport.

Air corridor

requirement

All civil aviation staff must implement the general principle of "ensuring safety first, improving service and striving for normal flight".

set up

Air corridor refers to the air passage which is usually 10 km wide (5 km on both sides of the line) and is located over the areas near large and medium-sized cities with dense airports.

According to people in the air traffic control industry, air corridors can be set up when necessary for airspace management and flight missions. The air corridor is mainly used for aircrafts to enter and leave airports in large and medium-sized cities. If restricted by conditions, its width shall not be less than 8 km. The air corridor also needs to be clear about the direction and flight altitude.

objective

The purpose of setting up air corridor is to make the aircraft fly in strict accordance with the corridor and avoid the aircraft entering the restricted area outside the corridor.

Implementation (contact, guidance, supervision)

CAAC has seven regional administrations: North China Administration, northeast administration, northwest administration, East China Administration, Central South administration, southwest administration and Xinjiang administration.

Air traffic corridor control is implemented by air traffic control units, namely: tower air traffic control room (hereinafter referred to as tower control room); air traffic service report room; approach control room (terminal control room); regional control room (regional control center); dispatching room of CAAC Regional Administration (hereinafter referred to as Administration dispatching room); general dispatching room of CAAC air traffic administration (hereinafter referred to as general dispatching room).

structure

At present, China has 11 flight information regions: Shenyang, Beijing, Shanghai, Wuhan, Guangzhou, Kunming, Lanzhou, Urumqi and Taipei, Hong Kong and Sanya. The control zone is the control airspace extending from the earth surface to the prescribed upper limit.

The route is an air corridor with a certain width and the center line determined by the radio navigation facilities, which is a control area or a part of the control area. Air traffic service route is a route designed to provide air traffic service and bring air traffic into it.

Take off using the same air corridor

Without considering the influence of wake

(1) Between aircrafts at the same speed: · when flying on different tracks, the track difference is greater than 45 degrees, and the lateral separation is implemented immediately after takeoff. 2 minutes after the previous aircraft takes off, the latter aircraft can take off, but if flying out in the same air corridor, it shall not be less than 5 minutes.

(2) Between aircrafts with different speeds: · when flying on different tracks, the track difference is greater than 45 degrees, and the lateral separation is implemented immediately after take-off. One minute after take-off, the aircraft with faster speed can be allowed to take off from the aircraft with slower speed.

Take into account the standard of takeoff wake interval

(1) Same runway, 2 minutes.

(2) (5) 3 minutes when the aircraft takes off using part of the same runway.

New functions and new uses

Open the air rescue corridor, and the critically ill patients can be transferred by helicopter. The trans regional organ transplantation will be more convenient.

"One belt, one road" intercontinental corridor. There's no connecting flight. It's direct.

At the first Innonation air summit, the perfect integration of aircraft and business communication broke the Convention and held a banquet at an altitude of 10000 meters.

Cooperative transnational tourism special line.

Wangtianshu air corridor

Wangtianshu air corridor is located in the National Nature Reserve 19 kilometers northeast of Mengla County, covering an area of 20 hectares. It is a tropical forest community dominated by wangtianshu, a national first-class protected plant.

Wangtianshu is one of the Endemic Tree Species in Xishuangbanna, only distributed in buwa, jingpiao and other places in Mengla County. Wangtian tree belongs to Dipterocarpaceae, evergreen tall tree. Because it is tall and straight, as high as 70 or 80 meters, it pierces the blue sky like a sword, more than 20 meters higher than other trees, green branches and leaves gather at the top, forming a "forest on the forest" landscape, and has the reputation of "giant in the forest" and "Prince of China and the United States in the forest".

The "air corridor" erected on the Wangtian tree is 2.5 km long. The bridge is supported by a naturally growing tree, suspended by steel cables, protected by nylon ropes and nets, and stepped by aluminum alloy ladders. Each section of the bridge is connected with a wooden platform on the trunk. The suspension bridge with a height of 34 meters, on which there is a small amplitude of shaking. It connects the primeval forests on both sides of the road, and you can enjoy the exotic scenery of tropical rainforest in a broad view. In addition, there is also a 1000 meter stone board tour road in the forest, which forms a three-dimensional circular tour line with the air corridor.

Along the murmuring stream in the dense forest, drill into the deep valley, and watch the various tropical plant communities. There are more than 30 kinds of animals such as wild elephants, bison, gibbons, etc. in the forest, there are more than 10 kinds of precious trees such as bamboo cypress, stone catalpa, cycas, Yunnan jimaosong, Xishuangbanna tuanhua tree, and more than 30 kinds of precious medicinal plants such as Maqianzi, meichengmu, huayelongxueshu, etc. Lianas, epiphytes and ferns in the middle of the forest, especially the cruel strangulation, make you dizzy. If you are lucky, you can also pick wild fruits such as Sanya fruit and olive by hand.

Air steel structure corridor, national key scenic area. Located in the south of Yunnan Province, Xishuangbanna Dai Autonomous Prefecture. There is a canopy air corridor in the virgin forest of Mengla County. The corridor is more than 700 meters long. It is supported by skylard trees, tied with steel cables and paved with wooden boards. Visitors can overlook the green ocean of tropical rainforest here.
