I agree that relevant NOTAM information is far from easy to spot but it certainly helps if you're aware of the major hazards that you are likely to encounter.
It's August and we're well into airshow season. Pilots should be aware of this and look hard for the obvious hazards. This information is not exclusive to NOTAM's/PIB's. Lists of upcoming airshows appear in flying magazines, local/national press, flying clubs etc...Isn't this part of our process before every flight?? For example, the weather is CAVOK, therefore it's likely that more air traffic will be about. The wind is westerly so traffic patterns can be anticipated on passing airfields; and that's the direction I'm working on if the engine goes quiet; there's an airshow down the road so it might be wise to avoid the area...It's all part of flight planing, isn't it?
It's amazing how relevant information leaps out at you (from any source) when you know what you're looking for.
