Indra Systems Manage the Air Traffic in Eight Regions of China

• The company has successfully completed the implementation of the Chengdu and Xian air control centres

• Indra's state-of-the-art systems manage an airspace of more than four million square kilometres, eight times the size of Spain

• The multinational's technology provides route, approach and tower services for the Shuang Liu airport, one of the most important in the country with 240,000 flights/year

Indra has successfully completed the implementation the Chengdu and Xian air control centres in China that manage the air traffic in the upper airspace of more than eight regions in the country for a total of 4.2 million square kilometres, or more than eight times the size of Spain. The company has equipped the Shuang Liu international airport, one of the most important in China, with its state-of-the-art technology for air traffic management.

Chengdu is one of Asia's largest air control centres. At this location, the Air Traffic Management Bureau South West (ATMB SW), which reports to the Civil Aviation Administration of China (CAAC), uses Indra technology to control the upper airspace of five regions in China: Yunnan, Tibet, Chongqing, Guizhou and Sichuan.

This new control centre has more than 400 air controllers who are responsible for an area of 2.3 million square kilometres. To manage this space effectively, Indra has implemented an advanced 4D trajectory flight management system (3 dimensions + time), as well as communication and route conflict prediction systems. With approximately 70 air controller positions, Chengdu manages the traffic of 17 international routes and about 30 domestic routes.

Indra has also equipped this centre with an air traffic flow management and control system (Air Traffic Flow Control and Arrival Manager, or ATFCM-AMAN) that makes it possible to efficiently sequence departures and arrivals within the network of 50 airports that operate in these five provinces.

As far as the Xian control centre, which is managed by the Air Traffic Management Bureau of North West (ATMB NW), it is responsible for controlling an area of 1.9 million square kilometres, corresponding to the regions of Shaanxi, Ningxia and Gansu.

The project to put the Xian and Chengdu centres into operation stands out because of its high technical demands and short time frame. The company's technology will allow Chinese air controllers to handle the double-digit air traffic increments that are estimated for the upcoming years.

The Director General of ATMB, Wang Liya, stated that he is "very pleased to have commissioned in record time Chengdu's ACC. In addition, the control towers, terminals and control areas operated successfully at the same time. The Centre is a fundamental enabler of aviation growth in the corridors Europe-Asia, Western Route, Northeast China and the Southwest region. ATMB and Indra project teams working together can be proud of their achievement"

On the other hand, Indra has delivered simulators to train Chinese controllers in the same environment and with the same equipment it has implemented, along with a validation system for testing and validating any modifications to procedures, operations or software in a secure manner.
