tmmorris,
You asked: "Maybe inadvisable, DFC, but you still haven't shown them to be illegal for private flights. Indeed the CAA published a paper (last year? what happened to it?) discussing two separate issues:"
There was an outcry against the proposal by a number of commercial operators. One can imagine why - i.e. folks would be prevented from doing what they have already been doing for some time..... and the CAA, to their credit, are thinking again. There are places in UK where there are "private" letdowns based on GPS, these have been properly surveyed and are known to the CAA.
Hopefully the next step is for the CAA to admit that properly surveyed GPS approaches, flown by properly trained crews, in properly equipped aircraft ARE safe and therefore can be approved and formally sanctioned.
