I can understand how this happened - the lure of a lump of tarmac exactly where you are expecting it to be (almost) - "We must be right, look there it is!" etc... But a trivial question: Who updates Eirjet's EGPWS? As far as I know, the one fitted to our planes would start to really object if you tried to land at a "non-airfield". Maybe the Irish CAA oversight people might like to comment as to their fitness to hold their positions. And what is the status of the rest EI registered aircraft flogging around the world? Probably very similar if this is the level of their oversight. And as EGPWS is a required fit, maybe all EI registered aircraft should be grounded until it is verified that they meet all relevant requirements and are fit to fly?
