Drauk,
You need to do something about the route validation.
I understand that you have it limited to the London FIR at present?
So put in a route:
EGNH Blackpool
EGNS Isle of Man
EIDW Dublin
EINN Shannon
The route was accepted, but when I plotted it on the map, is was clearly well out. While for something this far out it is obvious, but if it wasn't so far out, it might not be obvious to the use.
