Air China and Air China Cargo are to expand the use of Boeing's Airplane Health Management (AHM) system to monitor the in-flight condition of the carriers’ Boeing 777 and 747-400 fleets.
The new agreement adds 42 in-service and on-order airplanes to a previous agreement to monitor 117 Air China 737s that are in service and on order. Air China is Boeing’s first Chinese customer for AHM and the 33rd commercial customer overall.
"We are certain that Boeing's Airplane Health Management will benefit our passengers and cargo customers who count on Air China and Air China Cargo meeting our schedules," said Air China Chief Engineer Zhong Detao. "This will improve our entire operation."
Airplane Health Management captures and evaluates critical real-time in-flight flying condition data and relays the information to maintenance controllers. That allows the airline to turn a potentially time-consuming and costly maintenance delay into a well-planned and more easily accomplished repair. Airlines are better able to meet flight schedules, benefiting the airline, passengers and other cargo customers.
Air China operates 10 Boeing 777-200s and 10 747-400s. Air China Cargo operates seven 747-400 freighters, including two Boeing Converted Freighters.
