Here's a dilemma for you. PC1 (or CAT A for earlier types) will require a profile to be flown as per RFM. The profile will require the predication of LDPs etc on rad alt heights. Rad alts measure height directly under the aircraft .......... so unless you are flying into anything other than a football pitch you will never have enough accurate height data to fly the profiles. QED PC1 or Cat A will not be possible going into most 'primary sites' in 'congested' areas. We might as well go home then.
