70% of Flight Delays in Guangzhou Area was Due to Air Traffic Control

The flight regularity rate of Pearl River Delta area was lower than the national average for a long time. At the recently held Pan-Pearl River Delta Airport Cooperation and Development Forum, Zhang Jian, Director of Air Traffic Control Bureau of the CAAC Central and Southern Regional Administration, said that as aviation industry entered a new speedy developing period, the current air-space capacities of the central and southern areas were almost saturated and became a bottle-neck limiting the capacity of air traffic control system, thus difficult to fulfill the demand of flow growth in the next ten years. As understood, the Pearl River Delta region was the flight routes rendezvous point of Beijing-Guangdong and Shanghai-Guangdong; flights from Beijing and Shanghai to Guangzhou always experienced flow control affected by flight capacities. The flight regularity rate was 77.8% for Guangzhou Airport in 2009; 32668 flights were delayed due to flow control, three times the delays compared to 2004. Because of the constriction of aircraft flow, the flight regularity rate of Pearl River Delta region was lower than the national average for a long time. In 2009, the flow control carried out in Guangzhou area involving air-space was 71% of the total, while 20% were due to weather conditions. For this, Zhang Jian said, "air-space is the key element in applying flow control." At present, he said, central and southern region had established 22 temporary flight routes, an air-spacing structure initially capable of flexible usage of air-space, but the closely related regulations, mechanisms and information systems were not yet perfected, so as to cause the relative deficiencies in air-space coordination and management ability, limiting the effectiveness of flexible air-space usage.
