Worth remembering that the majority of these NOTAMs are Advisorary and not Avoids and the military (and any other significant airspace user for that matter) is duty bound to advise on significant air activity. Better to be aware of possible activity than get a fast jet up your backside surely?
Out of curiosity does the fast jet traffic get any collision avoidance info from my transponder squawk?
The notams are informative in that you know there are excercises going on, but not usually practical to avoid the area because they are so big. It would be good to know the military have something equivalent to the civilian TCAS...
Although the one I wonder about more than the occasional exercise notam, is the HRA. Does the usage really justify the size and daily active, or could it be smaller sections activated by notam, or have VFR corridors through it available to light aircraft.
