GE Installs RNP Flight Paths at Lijiang for Sichuan Airlines and Air China

Chinese airlines are proving that Performance-based Navigation solutions, like these RNP flight paths, solve many of todays most challenging air traffic management problems, said Steve Forte, general manager of GEs PBN Services business.  We have been providing flight paths in China since 2004 and are pleased to be expanding our RNP work there to deliver benefits to Chinese airlines and the communities and passengers they serve.
 
RNP technology couples GPS satellite navigation with onboard flight-management technology to provide   precise lateral and vertical aircraft guidance independent of ground-based navigation systems such as ILS.  If it werent for RNP flight paths, the loss of the ILS at Lijiang would prevent aircraft from landing there during periods of low visibility or when cloud ceilings are below 1,200 feet. The GE-designed RNP provides precision guidance to the runway, allowing equipped aircraft to continue to operate even during periods of reduced ceiling and visibility. Both Sichuan Airlines and Air China expect to use the RNP paths this month.

In addition to the Lijiang RNP flight paths, GE worked with Sichuan Airlines in September to validate RNP paths for its fleet of A319s at Lhasa airport, located in Chinas Tibet Autonomous Region. The RNP paths, now in revenue service there, allow Sichuan aircraft to safely arrive and depart the airport through rugged, mountainous terrain, in all kinds of weather, both day and night.  Without RNP, the airport is accessible only during daylight hours in good weather conditions.  

The recent RNP flight validations continue the growing partnership between GE and Chinese aircraft operators who are working to implement PBN solutions that save time and fuel while improving safety and schedule reliability.  In addition to Lijiang and Lhasa, GEs PBN Services business has implemented RNP paths at four other Chinese airports - Bangda, Yushu, Linzhi and Jiuzhaigou -and has designed and deployed RNP paths for two other Chinese airlines - China Southern and China Eastern.

RNP Services is the most recent product to become ecomagination qualified, having completed GEs rigorous ecomagination Product Review (EPR) process. The evaluation focused on the technologys operating and environmental benefits, which include demonstrated emissions reductions, fuel and costs savings. The technology is an example of GEs commitment to help customers address business and environmental issues with innovative technologies and services.
