Thanks for the feedback
Feedback appreciated chaps - Didn't realise that pre-flight briefings don't apply post-event (which is a pity as it'd be a useful way of seeing what was/wasn't NOTAM'd).
Also handy to know about the R numbers - will remember that for future reference.
I'll also suggest that when the NOTAM's are printed off at our club (done daily and pinned to the wall for all to see) that a call should be made to the AIS Information Line for any last minute updates. All useful stuff, cheers.
