I agree that a lot of NOTAMS should never be accepted. I agree that the official promulgation of NOTAMS leaves much to be desired.
However the reality is everyone has the right to our airspace. This sometimes means that a minority will use our airspace for their special purpose - for example aerobatic competitions. In addition it also means there are occasions (security, hazards etc) when the airspace should be restricted. I think we all recognise those needs.
For me it is wholly irresponsible for us not to pre-flight NOTAMS. Moreover I dont buy that it is difficult. There are numerous sources of graphical NOTAMS that really do provide all you need and numerous ways of accessing these.
It takes me literally a few minutes to self brief before a flight. I am not going to claim I do so before absolutely every flight but I do for the very vast majority.
Quite simply I think those that dont, whatever their age are negligent.
When I started flying, some what before some of the posters so far, things were different, but that is irrelevant. Times gone bye and we could do T and Gs at Gatwick. Sadly, perhaps, the world has moved on.
