I agree that PPR is valid in some situations; such as a private strip with operating limitations. However, it seems to be applied with a ridiculously broad brush; most of the places I have called for PPR have just said "yes, no problem", and when asked if there is anything in particular I need to know, they say no! Then why are you asking for PPR at all, at a large, well equipped, airfield?
I know the wonderful USA is often pointed to as an example, but I have flown to hundreds of airfields over there, and have only encountered one, single airfield, where PP was R. Apart from a love of bureaucracy and rules, I see nothing that rules the majority of Europe's PPR airfields out as particularly different...
