The fact of the matter is the extension to the west was probably never meant to happen in the original airfield layout of years gone by and this is clearly borne out by the houses/church almost touching the runway. Homes being 40m or so from the charlie taxiway is incredibly close and surprised this was allowed to stay with plans for the expansion back in 2011. What is done is done although my recommendation would have been to relocate charlie further east of its existing location to mitigate these issues. What is clear is that any further expansion of the airport will be even more closely scrutinised and I personally don't believe the airfield has the geographical size to accommodate any further traffic, it is space limited and problems would then revolve around backtracking issues etc so the target of 10mppa is way off and likely never to happen!
