But many of you here are conflating failure to obtain permission with a host of other poor planning and airmanship issues. My point is not that anyone should be able to turn up out of the blue without having done any preparation and without regard for others. I'm saying that a system which requires one to obtain permission in advance just to visit is unnecessarily restrictive (sheep grazing strips excepted!) Of course you consult NOTAMs, weather and other resources to plan your arrival.
I come back to this: if other countries with even busier infrastructures don't bother with PPR, why has it taken such hold over here, and with such apparent enthusiasm?
