Flew about 12 flights with Atlas, and there was little consistancy until the end. Even then odd frequencies would be given with traffic west of london sharing with Essex traffic so obviously not a lot going on.
I had to make my exit routes 6 miles long just to go through the Atlas stuff before leaving 112.
If I was doing flights for myself, then I could have put up with it but training flights were not that easy and subject to delays which wasted students time and money especially when put on standby whilst they try and find the flight plan and authorisation used to exit 112 45 earlier.
Thankfully nothing like this will be needed again - nothing against the RAF.
As to the traffic estimate produced by Atkins in the report published by the DfT I hope someone in the DfT asks for their money back, as they got it spectacularily wrong.
