I have had an even better idea, in addition to keeping our customers in a procedural environment for longer, let's TURN OFF all our radars and enroute navaids along the west coast of the UK and save a bit on the electricity bill at the same time.
After all, the US provides GPS for free and the pilots NEVER input the wrong way-points so they WILL all be safe, albeit burning more fuel because they are flying further at a lower than optimal altitude.
One more thing, let's close ALL the Advisory Routes just in case we might have an incident and only provide Basic Service below FL195, that'll save a few bob in ATCO salaries and reduce our corporate liability.
