I suppose it will I fly from sherburn and the new rule is a standard overhead join at 2000 feet
How exciting! Perhaps they can mention it over the radio when people call up to join, along with all the other rubbish r/t about not overflying villages etc. Then pilots inbound can contend with trying to spot everybody else on an "ECHO departure/arrival" flying around in a 5 mile wide swathe at all kinds of altitudes.
Unfortunately something as simple as funnelling everyone into and out of the place with set routes doesn't really work all that well when people just tend to fan in from the general direction of Selby and all report the same position/routing.
Are they altering any of the circuit patterns do you know?
