One point that has not been mentioned is that the aerodrome is allowed 80 movements per rolling hour, So the hour starts at 00, 15, 30 and 45. If the cap is broken it is a bit more than a please explain.. In some modes it would be quite easy to do. It is all artificial and political claptrack, but may explain some of the unexplained vectoring. The Shift Manger relies heavily on the arrival list and the times they predict. It's also one of the reason why on occasions there is nothing on final and you are sitting there like a xxxxxxx. Come the next 15 minutes things start to move again but you may only have a few lots to be divided up between the 2 runways. The cap does not give a rats about your CTOT or any other time requirement.
