China Southern Airlines (NYSE:ZNH) (HKSE:1055), the largest airline in The People's Republic of China, is pleased to announce that its now fully operational System Operational Control center is already "worth its weight in gold".

Based on the latest advanced computer and communications technology, the SOC system - as the operational heart of China Southern Airlines - provides for the centralized, real-time, scientific and standard control and management of the airline's overall flight operation, including flight schedule, dispatch, balance, crew management and other aspects of flight coordination. The SOC offers such functional modules as Movement Control; Flight Planning; Flight Tracking; Load Planning; Meteorological Function and Data Integration.

According to Mr. Hao Jian Hua, Chief Pilot, China Southern Airlines, the super high tech airline monitoring center at Baiyun International Airport that dispatches all of the airline's domestic and International routes is paying off with major savings to China's largest airline.

The SOC system has helped China Southern Airlines make 1,623 flight adjustments resulting in a profit of RMB 31.46 Million (US $3.8 Million); the SOC's computerized flight planning has saved 2,368 tons of oil - worth more than RMB 6.63 Million (US $800,000) and the SOC has taken advantage of the price differences and planned for the loading of 28,860 tons of aircraft oil in Hong Kong, worth more than RMB 27 Million (US $3.2 Million).
