Being an area controller wake vortex separation is somewhat overlooked, however I do give consideration in certain circumstances. In both examples given I would have to wait for 5 miles laterally constant or increasing and could then go for it. Likewise if they were both going in the same direction on the exact same track my book just says wait for the B767 to overhaul by 5 miles and then I'm free to descend/climb it through the level of the Cessna. In this case however I would normally use vectors to keep the tracks separate so wake turb cannot come into it. Is it bad that wake isn't considered in area control? I probably encounter
maybe one separation a YEAR that may fall below the minima for approach.
I get more complaints about vortex on climb outs usually following B757's or MD11's, however I have also had requests to change course slightly from a B737-300 following a B737-800, it was 16 miles behind!!!!!!!! Strange stuff this vortex...
