Private I was just commenting on your comment that Commercial pilots build routes using lat/long's which is complete and utter bollocks apart from certain situations one of which being the the North atlantic track system.
As I said you have some awfully weird ideas about what commercial pilots do, the equipment we use, and they way we do things.
Yes GPS is a tool as Genghis has pointed out but its a tool in suite of tools and the lack of it is no great hardship. Most pilots wouldn't even have a clue it wasn't working for inter europe trips.
