Topbunk, I think the point he was trying to make was you don't need radar to have "safe" RVSM. As I pointed out on the last page what most of Africa needs is ATC that works effectively both within individual countries and across borders. If you put in 100% radar coverage across the whole of Africa tomorrow it would make no difference to the ATC environment that we operate in because you can still fly over several countries without talking to a controller (despite trying)
