In the UK the categories are:
Public Use Licence where the airfield is licenced under Article 103 of the ANO, and has to be,
inter alia '. . . . available for the take-off or landing of all aircraft to all persons on equal terms and conditions, . . . .'
Ordinary Licence where the airfield owner/operator can specify whatever conditions he/she so wishes, and
Unlicenced.
This isn't quite the same as PPR but possibly linked to it. Even a 'public use' licenced airfield could be PPR on occasions and an 'ordinary' licenced (or unlicenced) not be.
PPR really meant 'phone first' although the fact that some will give that approval over the radio muddies the water a bit. I onced phoned quite a well known airfield for PPR on behalf of someone else and was told 'Yes but why are you bothering phoning?' 'Because it says PPR in the AIP' 'Oh! Most people don't bother!!' Oh well
