Indeed Jan. An airfield I called for PPR and a few details recently appeared to have a website of pilot information and I mentioned it when on the phone. The airfield quite vociferously told me that the website was nothing to do with them and operated by a small group of local aviators and they did not accept responsibility for anything on it.
Contrast that with my home field Redhill with an excellent website maintained by the airfield operator and which with respect to anything approaching booking out says :
"It greatly assists ATC if pilots adopt the following, modified' RTF procedures:
"First call outbound: Redhill Tower (callsign) outbound information …. QNH …."
This is the only information required.
