Have you noticed how the CB
love to bother with your stack patterns, so that you have to create stacks in the middle of nowhere, with an acft choosing to make it right hand, the next left hand, the third one... makes some "8" patterns...
Of course, if the traffic is
really low, we'll also do it fast and manually... but the CBs are of a curious character, and always want to see what happen when they visit us at hub times...
