BF - If you have departures you need a 5/6 mile gap, if you don't then 3/4 miles should suffice.
When there are no departures the tower controller should instruct the radar controller to pack inbound a/c to minimum vortex spacing.
However, EDI has still to master the art employed at TC and Manch of pack-one, gap-one (etc), when there are just a few outbounds but a load of inbounds. Although some controllers endeavour to expedite the traffic in this manner there are no procedures/guidance laid down at EDI to facilitate this method of working.'
