I was extolling the vitues of SD today to someone, who I had got to download it the other day to play with. He mentioned that he thought the low level route wasn't very prominent. Manchester often get their airpace near the low level route busted. On the CAA chart and memory map it is clear and is shown in white, seperating Liverpool from Manchester. I know you can turn off CTL and the whole area turns white. I don't suppose it could be portrayed in a similar way (white) when the CTL is turned on could it?
