Sorry to sound like the old f**t that I am but please, please - in order to stop the thread degenerating again into stories about plotting can we stop using "map" (unless it is a techie term) when it seems the problem was an seemingly an incorrect nav
database. AFAIK the aircraft didn't have a built in Electronic Flight Bag, maps/charts would have been carried on the crew's own iPads, as discussed earlier
....but yes, rumour has it the problem was generated in London, not at EINN.
