B407 PLT CHALLENGES ACCUSATION OF DC ADIZ VIOLATION WITHOUT PROPER XPONDER CODE ACTIVATION PRIOR TO ADIZ ENTRY.

Narrative

NORAD IS CLAIMING I ENTERED THE WASHINGTON; DC; ADIZ BEFORE I RECEIVED MY XPONDER CODE FROM QUANTICO APCH. IT IS MY POS THAT I DID NOT ENTER THE ADIZ BEFORE RECEIVING MY CODE. AFTER RECEIVING MY CODE FROM QUANTICO APCH; I CONTINUED FOR LNDG AT HEF; WHICH TOOK APPROX 15 MINS. UPON LNDG; I WAS TOLD TO CONTACT POTOMAC TRACON. THE PERSON ON THE LINE SAID NORAD HAD CALLED AND SAID I ENTERED THE ADIZ BEFORE GETTING MY BEACON CODE. I TOLD HIM I WAS FAIRLY SURE THAT WAS NOT CORRECT BECAUSE I CALLED AND RECEIVED THE CODE BEFORE XING THE RTE 301 BRIDGE; WHICH IS AT THE BOUNDARY OF THE ADIZ. THE MAN THOUGHT THAT I MIGHT BE CORRECT. HE SAID HE WOULD CALL ME BACK AFTER CHKING THE RADAR TAPES. TO DATE; 2 DAYS LATER; I HAVE NOT RECEIVED A CALL BACK. CONTRIBUTING FACTORS: THE AIRSPACE SYS IS NOT DESIGNED TO HANDLE THE TREMENDOUS ADDED BURDEN OF TRACKING ALL THE VFR ACFT AROUND 4 CLASS B ARPTS. RADAR COVERAGE IS NOT SUFFICIENT TO COVER LOW ALTS -- ESPECIALLY FOR HELIS. THIS IS ESPECIALLY TRUE UNDER MVFR IN CLASS G AIRSPACE WHEN HELIS ARE STILL FLYING; BUT YET CANNOT BE IDENTED ON RADAR. IN SOME CASES ARE DENIED ENTRY AND PREVENTED FROM COMPLETING OUR MISSIONS BECAUSE OF POOR RADAR COVERAGE.
