BIK,
Avoiding Action is rarely used because we've let separation erode.
It is mainly used outside controlled airspace because of pop up traffic or fast moving military traffic whose intentions we do not know and starts to do a dirty dive right towards your aeroplane, if you like I can refuse to provide you with a Radar Advisory Service and just give you a Radar Information Service (or if I'm really busy giving avoiding action to IFR traffic under a Radar Control Service in Class E airspace against pop up traffic 12 o clock 1 mile no height information) I could give you a Flight Information service and let you try and sort things out yourself against primary radar returns or that fast moving military traffic you've no chance of seeing.
We do a bloody good job stopping aeroplanes banging into each other, a darn sight better than any computer could do via datalink.
Flyer it'll be you lucky day if I ever tell 6G to orbit and follow you from dumbarton, when I do, I'll expect the biggest bottle of single malt you can get your hands on
