"Behind the door marked beware of the tiger..."
Not being a member of a club, AOPA or any other flying organisation is not an acceptable excuse.
You do have to know that these things exist, and I'm willing to bet good money that if I go to the clubhouse now and ask if anyone knows that they do, no-one will.
I've been to the CAA site and hunted around, typed "notification service" into the search engine, which got nowhere, and eventually found this link
http://www.caa.co.uk/default.aspx?catid=33 which I offer as being helpful and useful to all.
I also went to the AIS site - couldn't find the equivalent there, perhaps someone else can and post it.
Regulation is, above all, about safety - and not employing endless bureaucrats - and in order for regulation to work, the regulators have to communicate with the regulated, not just say stuff like " is not an acceptable excuse". If enough of the regulated don't know things, then the regulators are the ones at fault. Maybe it's just me and I'm stupid, but I don't think so. My name is Bernard Newnham amd I'm willing to be a beta tester of websites etc. I believe in constructive criticism.....
