Its need because ATCSOCA is such a pile of bollocks.
There has always been problems with gliders in the areas on the class E.
And the black isle is still available for PPL training.
As long as the radar is manned I can't see it being a problem.
Its just to be honest resetting things back to the old days of procedural control at INV. VFR traffic not needing to be separated from traffic on finals by 5 miles.
Personally I think it will be better than the current pile of pish they have to comply with.
