Oceanic airspace is patently more anally retentive nowadays than it was when I worked it if every error has reporting action taken on it. H/F comms are diabolical, the pilot reports his current position, his estimate for the next position and then the subsequent position after that, the last one probably being the 'error'. Even if the pilot gives his next position as incorrect who is to say the pilot did that? Because H/F is so crap, perhaps Ballygirreen misheard it therefore it is not the pilots fault. Aircraft GPS systems are highly accurate, yearly, how many real GNE's occur, bearing in mind the volume of modern aircraft that fly trans-Atlantic? probably one or two.
