IMHO no, contrary to that posted at 597 the reason for the current, and possible future, operation at CAT 1 is due to the lack of a full (ie 900 metre) approach lighting system on RWY 20 together with obstacles in the final approach area. The presence of the latter will preclude significant lowering of the Descision Height (ie the point at which a missed approach must be initiated) therefore it is not financially viable to extend the approach light system to faciltate adoption of something better than CAT 1.RVR minima.
The issue of runway width is only applicable for Code 1 & 2 precision runways which requires a minimum width of 30 metres (ref ICAO Annex 14) which SOU already has if it were applicable,
Has anyone any update of Aurigny having EVS (Enhanced Vision Systems) fitted to their ATRs? This was apparently being done to counter a similar approach minima problem at Guernsey and could accordingly be applied at SOU to enable a less than CAT 1 minima to be used.
