Sometimes they reject everything altogether and command idle logic instead
In X million cycles how many times has this happened?
(which can't happen with old 747-100's and 200's with steel cable to hydomechanical control.) Thus my position that the old design was safer from a "fail safe" consideration at spool up.
Did not an Evergreen 747 divert into LHR in the last year or two with unresponsive engines?
Your quote regarding from the press says:
focuses on errors introduced with a FADEC (Full Authority Digital Engine Control) software update that affected the B.777 equipped with GE90 engines.................So, the FADEC has already cased worries to the B.777 operators using GE engines. The British Airways aircraft was equipped with RR Trent engines, even if the software used to control them is probably the same (or mostly similar).
Well there's an enormous assumption if ever there was one!
