One thing to bear in mind is this:
Before the advent of AVBRIEF you had to pay quite a bit for met information from the Met Office, and that wasn't as much information wise as you can get from them now.
So - ask yourself this. Do you freeload from the Met Office and then, if everyone did that AVBRIEF would cease to be, so the Met Office would then be back to the monopoly that would enable them to charge what they wanted;
OR
Do you pay the (IMHO) reasonable subscription to AVBRIEF, where you get airfield as well as weather data, and keep things from returning to what they were before.
It often pays to think big picture
(And no - I'm nothing to do with AVBRIEF but have subscribed since its inception and am very pleased with the service).
