We could always have Trafficmaster installed as part of avionics kit.
'You are approaching junction 34, Southbound MI slow moving traffic for 6 miles expect 10 minutes delay, MI8 traffic Eastbound traffic flowing freely'.
Reckon you would get less hassle landing on the M18 than you would from Sheffield City Council for emergency landing a single at Sheffield airport!.
On a more serious note I am aware of a couple of instances where the police have closed roads to allow aircraft to take off following forced landings in fields not big enough to fly out of.
It seems the local bobbies do not have communication links with the CAA thank god.
Mmmmmm, a thought,,wonder what height Trafficmaster works to?, would be great for getting accurate fixes and even headings,,N/W/E or West!.
Would be great for the rotary boys to use as they are normally tracking via Motorways at low level!.
