We have the same problem over here at Parafield approaching OCTA. Only 2 inbound approach points Outer Harbour to the west and the Substation to the NE. OHB in particular can get quiet busy at times with the college and the other 3 or so flying schools all out at the training area west of Edinburgh as well as the LOE down the coast all feeding into it.
We have in the past year had 2 midairs approaching GAAP's I don't want a 3rd here at PF thanks.
So based on the current evidence I find myself agreeing with Dick.
