This has been done to death on all the UK forums but IMHO the only really objectionable situation is where "PPR by telephone" is insisted on -
Hi Peter,
In some cases and at some times this would seem pointless.
The reason phone (or on line with contact details) is insisted at my local field is:-
a) PPR by radio is not always possible as there is breaks in cover.
b) Three runways sometimes all being used.
c) The CAA want it recorded.
d) Safety info not yet in the flight guides.
e) If we don't know you're coming we don't know you're missing. (Inhospitable terrain).
f) For those who are incapable of self briefing.
D.O.
