Took off from NRT climb passed some icing condition. About 3 hours into the flight ADM center failed, after awhile all 3 ADM failed.EICAS showed so many messages. How could 3 ADM failed at almost the same time?? Any ideas??

Icing of the pitot tubes comes to mind. Just a guess.

Not only all IAS became unreliable, but also the altimeters. They all displayed difference value! At this time,Boeing still can't figure out the problems yet!
