Cloud cutter...I agree with you that AR is most definitely an accident waiting to happen. When I was instructing there I would try and conduct as much training as possible over the Firth of Thames. Sure, I was risking it being over water but after a number of scares in the AR training area it was the best of a bad situation.
Viagra, as for a TCAS on GA machines. Having used one on a light a/c it would be constantly going off in areas such as around Ardmore and it would be a waste of money.......
