MJ I've never flown in Scotland, but its on my list, I hope your friends will be willing to talk to me too, I realise I could have just put 7000 in and carried on but was once told it doesn't do controllers any favours just heading towards their zone without them knowing your intentions, so if they see the appropriate squawk they know you have a reasonable amount of situational awareness and should be on frequency, incase I do anything daft, I've been given traffic info also, but I don't think that's what the system was designed for.
Cheers, Jim
