There are very few real cases for PPR. I can think of:
- A private strip, needs to issue a permission (obviously - would you park in somebody else's drive?)
- An airfield which is public but which has had issues with big fly-ins. Mind you, anybody organising a fly-in to some airport and not contacting the airport first (to check apron space etc) is a Grade A d***head.
- PPR/PNR for Customs
- PPR because it is military. Lots of Greek and Turkish examples here, although they tend to allow local-reg planes to fly there without it, which shows it is just a job creation scam
Otherwise, it tends to be a job creation / self-important exercise.
I agree people should read notams but we have the "UK GA disease" to contend with, where a large % of pilots do not use (or won't use) the internet, fly with the transponder siwtched off, etc. This probably ensures a lot of the PPR airfields continue doing it.
