Narrative:

Two hours before takeoff I self-briefed the weather/NOTAMS using duats. As is typically the case; the majority of the duats output consisted not of weather information; but of NOTAMS that didn't apply and/or NOTAMS that have been out there for years. In any case I did not notice any significant NOTAMS for the route or destination. Approaching 90 NM from destination I picked up ATIS. ATIS had a NOTAM for aerial demonstration flying at/below 2500 ft within 5 NM radius of my destination airport; avoidance advised. This came as a surprise! I called FSS to ask if the airport was taking arrivals; to which they responded that the airport was not closed...so I pressed on. Upon arrival outside destination airport class D airspace; I found radio traffic to be typical and other airplanes in the pattern. The flight ended uneventfully. I didn't save my duat briefing so I'll never know if that NOTAM was part of the briefing or not. The contributing factor is the persistence of these years-old NOTAMS about avoiding nuclear power plants; procedures to follow when flying to/from the USA; avoiding large sporting events; and knowing interception procedures. It is very easy to skim over these NOTAMS and miss a new; important NOTAM. A typical duats output has 18 pages of NOTAMS! Corrective action will be to exercise renewed vigilance when reading NOTAMS.

Title: C182 PLT EXPRESSES DISPLEASURE WITH THE PERTINENCE; TIMELINESS; QUALITY AND VOLUME OF NOTAMS RECEIVED WITH FAA BRIEFINGS FROM DUATS.

Narrative: TWO HOURS BEFORE TAKEOFF I SELF-BRIEFED THE WEATHER/NOTAMS USING DUATS. AS IS TYPICALLY THE CASE; THE MAJORITY OF THE DUATS OUTPUT CONSISTED NOT OF WEATHER INFORMATION; BUT OF NOTAMS THAT DIDN'T APPLY AND/OR NOTAMS THAT HAVE BEEN OUT THERE FOR YEARS. IN ANY CASE I DID NOT NOTICE ANY SIGNIFICANT NOTAMS FOR THE ROUTE OR DESTINATION. APPROACHING 90 NM FROM DESTINATION I PICKED UP ATIS. ATIS HAD A NOTAM FOR AERIAL DEMONSTRATION FLYING AT/BELOW 2500 FT WITHIN 5 NM RADIUS OF MY DESTINATION AIRPORT; AVOIDANCE ADVISED. THIS CAME AS A SURPRISE! I CALLED FSS TO ASK IF THE AIRPORT WAS TAKING ARRIVALS; TO WHICH THEY RESPONDED THAT THE AIRPORT WAS NOT CLOSED...SO I PRESSED ON. UPON ARRIVAL OUTSIDE DESTINATION AIRPORT CLASS D AIRSPACE; I FOUND RADIO TRAFFIC TO BE TYPICAL AND OTHER AIRPLANES IN THE PATTERN. THE FLIGHT ENDED UNEVENTFULLY. I DIDN'T SAVE MY DUAT BRIEFING SO I'LL NEVER KNOW IF THAT NOTAM WAS PART OF THE BRIEFING OR NOT. THE CONTRIBUTING FACTOR IS THE PERSISTENCE OF THESE YEARS-OLD NOTAMS ABOUT AVOIDING NUCLEAR POWER PLANTS; PROCEDURES TO FOLLOW WHEN FLYING TO/FROM THE USA; AVOIDING LARGE SPORTING EVENTS; AND KNOWING INTERCEPTION PROCEDURES. IT IS VERY EASY TO SKIM OVER THESE NOTAMS AND MISS A NEW; IMPORTANT NOTAM. A TYPICAL DUATS OUTPUT HAS 18 PAGES OF NOTAMS! CORRECTIVE ACTION WILL BE TO EXERCISE RENEWED VIGILANCE WHEN READING NOTAMS.
