"Blue dot" Cincinnati chart could put you in the Washington ADIZ

Don't use that new "blue dot" Cincinnati Sectional chart before August 30. There's a "gotcha" that could put you inside the Washington, D.C., ADIZ (Air Defense Identification Zone) if you do.

Here's what happened. A little section of the ADIZ appears on the very eastern edge of the Cincinnati chart. When the ADIZ shrinks on August 30, it will no longer extend into the area covered by the Cincinnati Sectional. So the FAA has reprinted and reissued the 78th edition of the chart (identified by a blue dot on the front panel) and told pilots to start using the chart immediately.

The FAA was wrong. The blue dot chart doesn't become effective until August 30. AOPA Airport Support Network volunteer Robert Clark (Thomson-Mcduffie County Airport in Thomson, Ga.) alerted AOPA to the problem. The FAA has now issued a notam to make it clear that pilots should use the old 78th edition until August 30.

That said, if you're going to be flying that close to the eastern edge of the Cincinnati chart, make sure you also have a current Washington Sectional and a current Baltimore-Washington Terminal Area Chart on board. If for some reason you end up flying a little farther east than you planned, you'll need to be very aware of the ADIZ, Camp David, and a few other sensitive airspace areas.
