Maybe it's an idea for a magazine article? A bit on NOTAM background, and then tracing a NOTAM (e.g. one for an aerobatics competition) through the system from initial draft, submission, promulgation onto your AIS narrow brief? Alongside an explanation of the various options that the NOTAM submitter has (airfield, whole FIR, IFR/VFR etc) and how this affects the narrow route brief filtering?
I realise that not everybody reads these magazines, but still...
