CCTV.com News: Four-dimensional track flight is a refined control of the three-dimensional and time dimensions of space for all stages such as takeoff, climb, cruise, near advance, and landing. This is to deal with the severe challenges brought to the current air traffic by the continued growth of air transportation. The new round of air control system upgrades that the international civil aviation community is undergoing is also a new trend in the future development of international civil aviation.

Four-dimensional track operation is currently generally recognized by the international civil aviation community for the core operation concept of the next-generation navigation system, and is a revolutionary solution to the continuous growth of air transportation. Four-dimensional track operation is based on the application of new technologies, and can effectively upgrade the current air traffic management system to achieve accurate, controllable, safe and efficient.

Deputy Director of Air Control Department of the Civil Aviation Administration of China Kang Nan: The core is precise and controllable in time. Then, through the operation of four-dimensional tracks, the time control accuracy can be shortened from the minute level or even ten minutes level to the ten seconds level, which greatly improves our use of the operation efficiency of time and space. After

introduced four-dimensional tracks, the ten-second-level timed arrival control will greatly improve the efficiency of time and space resources. In flight operation and management, airlines, air traffic control, airports and other relevant parties use technical means to achieve high coordination, making operation management more convenient and efficient. In addition, the aircraft airborne system participates in the control operation, which facilitates all parties to take measures in advance to alleviate potential traffic congestion pressure, avoid flight conflicts, and improve safety guarantees.

Deputy Minister of Air Control Department of the Civil Aviation Administration of China Kang Nan: For five consecutive years, the growth of air transport of China's civil aviation has been maintained at more than 10%. Therefore, in the next five years, according to our forecast, it is possible to continue to maintain such a growth. This will bring great pressure and challenges to our air navigation guarantee for such a large amount of aviation market in our country. The realization of four-dimensional tracks provides a very strong technical support for us to improve safe operation efficiency.

In 2012 and 2014, Europe successfully achieved test flights from Paris to Copenhagen. At present, large-scale demonstration and verification tests are still being carried out. my country is the second country in the world to carry out this new technology test flight.
