Narrative:

I departed brandywine (N99) for ocean city, md (oxb) VFR and arrived without incident. After a 2 1/2 hour stop-over, departed oxb for lee airport (anp, annapolis, md). Flew north to ATR VOR, then outbound on the 290 degree radial to anp. No flight plan was filed. On landing at lee, I was met by united states customs officers. They informed me that on crossing the chesapeake bay, I had entered the washington, dc ADIZ without clearance or a discrete transponder code. Prior to departing N99, I received a WX briefing for my flight, including landing at anp. I did review the NOTAMS regarding washington dc, but they are very confusing. Referring to both the washington sectional and terminal, they clearly depict the special flight rules area (sfar 94). I mistook this for the dc ADIZ. Had I received a verbal briefing, as opposed to a computerized briefing, and filed a flight plan, I assume FSS would have advised me of the need for an ADIZ flight plan and the need to contact potomac approach for a transponder code. The major problem, I feel, is the FAA failure to clearly depict the location of the ADIZ and include warnings of the dangers associated with it on all charts, just as they do with prohibited and restr areas.

Title: A C172 SINGLE PLT VIOLATED THE DC ADIZ ENRTE TO ANP.

Narrative: I DEPARTED BRANDYWINE (N99) FOR OCEAN CITY, MD (OXB) VFR AND ARRIVED WITHOUT INCIDENT. AFTER A 2 1/2 HR STOP-OVER, DEPARTED OXB FOR LEE ARPT (ANP, ANNAPOLIS, MD). FLEW N TO ATR VOR, THEN OUTBOUND ON THE 290 DEG RADIAL TO ANP. NO FLT PLAN WAS FILED. ON LNDG AT LEE, I WAS MET BY UNITED STATES CUSTOMS OFFICERS. THEY INFORMED ME THAT ON XING THE CHESAPEAKE BAY, I HAD ENTERED THE WASHINGTON, DC ADIZ WITHOUT CLRNC OR A DISCRETE XPONDER CODE. PRIOR TO DEPARTING N99, I RECEIVED A WX BRIEFING FOR MY FLT, INCLUDING LNDG AT ANP. I DID REVIEW THE NOTAMS REGARDING WASHINGTON DC, BUT THEY ARE VERY CONFUSING. REFERRING TO BOTH THE WASHINGTON SECTIONAL AND TERMINAL, THEY CLRLY DEPICT THE SPECIAL FLT RULES AREA (SFAR 94). I MISTOOK THIS FOR THE DC ADIZ. HAD I RECEIVED A VERBAL BRIEFING, AS OPPOSED TO A COMPUTERIZED BRIEFING, AND FILED A FLT PLAN, I ASSUME FSS WOULD HAVE ADVISED ME OF THE NEED FOR AN ADIZ FLT PLAN AND THE NEED TO CONTACT POTOMAC APCH FOR A XPONDER CODE. THE MAJOR PROB, I FEEL, IS THE FAA FAILURE TO CLRLY DEPICT THE LOCATION OF THE ADIZ AND INCLUDE WARNINGS OF THE DANGERS ASSOCIATED WITH IT ON ALL CHARTS, JUST AS THEY DO WITH PROHIBITED AND RESTR AREAS.
