Boeing, in collaboration with Xiamen Airlines, has developed new Required Navigational Performance - Authorization Required (RNP AR) flight procedures at Wuyishan Airport in China.

Boeing, in collaboration with Xiamen Airlines, has developed new Required Navigational Performance - Authorization Required (RNP AR) flight procedures at Wuyishan Airport in China.

Xiamen Airlines is the first Chinese airline to use the advanced navigation capability of its Boeing 737 fleet, and trialled the 0.3 RNP AR procedures at Wuyishan Airport in December 2012.

Civil Aviation Administration of China (CAAC) Flight Standards Department director general Wan Xiangdong said that the implementation of RNP will improve safety and efficiency and reduce operating costs, as well as being more environmentally friendly.

"RNP really benefits everyone, the airport authorities, air operators and air traffic control by increasing safety and efficiency and reducing workload," Xiangdong said.

"RNP AR intends to allow aircraft to deploy global navigation satellite systems (GNSS) and onboard avionics."

Claimed to be the most capable system of its kind, RNP AR intends to allow aircraft to deploy global navigation satellite systems (GNSS) and onboard avionics to fly accurate flight paths without depending on ground-based navigation stations.

The implementation of RNP AR will allow curved approach paths, further evading terrain or noise-sensitive areas, as well as allowing airlines to fly precise, fuel-efficient, satellite-based routes, said Boeing.

Boeing ATM Navigation Services program manager Shawn Bailey said: "Prior to RNP, most airports around the world, including Wuyishan Airport, relied on conventional ground-based navigation stations which require more separation between airplanes, less efficient flight paths and often less stabilised approaches."

The entities involved in developing the flight procedures include Boeing Flight Services and Boeing subsidiary Jeppesen, Wuyishan Airport Authority and the Civil Aviation Administration of China (CAAC).
