Another IRU fault resulting in sudden departure from controlled flight?
Several months ago an A330 transiting across Australia suffered a transient electrical fault in IRU1. It caused AP1 to think the aircraft had pitched down ~40 degrees. Needless to say it pitched up in response. Fortunately they recovered and the aircraft landed safely after diverting.
I wonder if this did similar, only in the opposite sense
Very valid observation.
Could anyone comment on the chances of a lighting strike affecting an ADIRU?
Also FCOM specifies that pressure system controllers on this type get information from the ADIRU , could a malfunction on one of the ADIRU's lead to a decompression?
