The malfunctioning equipment could have been something required to cross the Atlantic for ETOPS and therefore they couldn't proceed to LHR.
Yes, the captain's words were that the Nav computers went into Degraded mode and were like "1975" era technology. Would that mean VOR and DME? Yes, quite hard to cross the Atlantic if this was the case. I wondered to myself if he had to hand-fly any part of the journey, if the autopilot requires fully functional Nav computers?
Or if there GPS as a backup? Need a pilot's opinion.
Either way I trusted his decision. Esp. in the days after the Air France incident there is no need to take extra risk while over an ocean. The flight landed around 2am and the replacement flight left at 8am the same day.
