A great candidate for an airpark.
All it needs is a GPS approach with a 300ft MDH - US-style. By the time that happens (no ATC, etc) UK GA will be on its last legs anyway.
It's a shame though. There are very few airfields on the s. coast and the extreme difficulty of driving along the coast (the A27 is a truly awful road, through Worthing and Arundel) means that one needs more airfields in order to derive utility value from GA flying. Make no mistake about it - the heath of US GA doesn't come from $150 burger runs.
