Rivet Joint, St Germain et al
Cheap is the success story for GPS based approaches, no ground equipment to maintain and no staff required for maintenance, plus an approach that is on the runway centreline, not offset as the current VOR/DME and NDB/DME approaches are. GPS was talked about three+ years ago, its not rocket science, where are the approaches?
An ILS for RWY 02 is not going to work, there is no business case for it It would have to be off-set to avoid Townhill Park hill. The resultant minima penalty would not be significantly different from the current non-precision approaches. A GPS approach may not improve the current minima, but you at least know exactly where the runway is when you pop out of cloud!
When the runway was being re-surfaced, myself and colleagues obtained an informal estimate to have a taxiway installed from the north end of the apron (around Stand 14). With the asphalt plant on site together with the contractors, price £40K. The perm "p***ing in the wind" comes to mind when we proposed it to the then BAA management!
