Its just seems like the Airbus troubleshooting trees are more focused. You have to use lots of that mechanic stuff on the Boeings because theirs aren't that great. The old DC10 FEFI/TAFI was light years ahead of Boeings FRM/FIM's and even when they went to the 747-400 with CMC's and all that other electrickery, they still just didn't seem to get it. I must be getting old but fixing aeroplanes by pulling the plug and having a cuppa just doesn't seem natural. I must admit I miss the days when "freed by percussion" was the sign-off du jour.
