Although what you say is quite correct it does surprise me that airfields don't take greater care to publish flight safety info. I know for a fact that 'another flight guide' than the one previously mentioned posts out to all the airfields they cover annually. Considering the fact that they then have time to send info in and the means to return it at no cost to themselves you'd be amazed at the number that don't bother. There is one regional airport that actually asks for payment for providing info! I should add that this was done as a back-up to amendments gleaned from the usual authoritative source.
