Below is the salient part of an article written in february. I don't know if it was posted at that time. China Eastern Airlines is mentioned.
“By the end of 2015, implementation plan will be wrapped up. All the aircraft shall be finished or in the process of installation,” the bulletin said. The plan has been in the works for the past couple of years but gained urgency in the wake of the Malaysia Airlines and AirAsia disasters, according to industry sources. It will apply to range of Chinese carriers, including China Southern Airlines and China Eastern Airlines.
It notes that improved communications between ground crews and pilots will help ensure safety in the country’s aviation industry, which has seen explosive growth in the past decade. Known for its relatively unsafe skies after a series of crashes in the 1990s, China has made dramatic improvements in fleet and operational safety, in part by working more closely with Western experts from Boeing and other aircraft and avionics manufacturers. (The deadly crash in Taipei this week of an ATR 72 involved a plane operated by TransAsia Airways, which is based in Taiwan).
The country is now looking to further enhance safety by mandating improved communications systems. “All certified operators must prove to CAAC the ability to establish two-way communication on any point of the route,” the bulletin said. “Such communication shall be accessible by all aircraft. The time of establishing communication shall be less than four minutes.”
China’s mandate to install so-called satcom systems on all domestic airlines could be a boon for a number of Western suppliers.
FLYHT Aerospace Solutions, of Calgary, Canada, is looking to gets its Afirs satellite communications and tracking system on China's list of approved technologies.
