PLT OF TBM7 DEPARTS W32 WITHIN THE DC ADIZ AND FAILS TO MAINTAIN DISCRETE CODE UNTIL BEYOND THE LATERAL EXTENTS OF THE ZONE.

Narrative

DEPARTING FRZ (FLT RESTR ZONE) FROM W32; I RECEIVED AN FRZ CLRNC OUT OF THE FRZ AFTER CALLING LEESBURG FSS AND THE FRZ RETURN CLRNC BACK IN. I HAVE BEEN FLYING IN AND OUT OF W32 AND VKX (BOTH IN THE FRZ FOR ABOUT 2 YRS) WITHOUT ANY SITS LIKE THIS ONE. DURING THE FILING THE FSS BRIEFER POINTED OUT THE ENTRY AND EXIT POINTS FOR THE FRZ TO THE SW; APPROX 20 NM AND 15 NM RESPECTIVELY. PRIOR TO LAUNCH AT W32 I RECEIVED A SQUAWK CODE AND FREQ AS IS STANDARD PROC. I DEPARTED THE FRZ UNDER CONTACT WITH POTOMAC DEP AND WAS WITHIN 5 NM OF EXITING THE ADIZ SBOUND. THE CTLR WAS BUSY HANDLING ARRS AT DCA AS WELL AS ME. SINCE I WAS NEAR THE EXIT OF THE ADIZ TO HELP OUT THE CTLR I SAID I WAS NEARING THE EXIT AND WAS GOING TO SQUAWK 1200. THE CTLR ACKNOWLEDGED THIS. I SUSPECT THAT MY SQUAWK OF 1200 CREATED AN ALARM ON THEIR SYS SINCE I MAY HAVE SQUAWKED 1200 JUST INSIDE THE ADIZ. SINCE THE WX WAS ROUGH (MODERATE TURB BELOW 10000 FT) AND SURFACE WINDS GUSTY AND VARIABLE; I DECIDED TO RETURN TO W32 WITHOUT LNDG AT MY ORIGINAL DEST. I MADE ONE PRACTICE LNDG AT SHANNON AND THEN DEPARTED TOWARDS BROOKE VOR. MY TA SYS POINTED OUT TFC WITHIN 2 NM AT MY ALT NEAR THE BROOKE VOR S OF THE ADIZ. I MANEUVERED MY ACFT SEVERAL TIMES TO 'GET OUT OF THE WAY' BUT THIS ACFT SEEMED TO CHANGE COURSE SO THAT I ALWAYS PERCEIVED IT TO BE A COLLISION THREAT. THIS CREATED AN ADDITIONAL SERIOUS DISTR IN WHAT WERE TURBULENT CONDITIONS. I CALLED POTOMAC AND STATED MY INTENTIONS TO LAND AT W32 PRIOR TO ENTRY INTO THE ADIZ. I DESCRIBED INTENTIONS AND MY POS AS 10 MI SW OF IRONS INTXN. AT THE SAME TIME; I AGAIN ATTEMPTED TO MANEUVER MY ACFT OUT OF THE WAY OF THE TFC WHICH CONTINUED TO BE DISPLAYED WITHIN APPROX 2 NM AT MY ALT ON MY TA SYS. POTOMAC RESPONDED TO MY FIRST CALL WITH MY ACFT CALL SIGN; BUT MAY HAVE MISSED THE REST OF MY XMISSION BECAUSE THEY ASKED ME TO 'STATE MY INTENTIONS.' MY SECOND ATTEMPT AT DESCRIBING MY INTENTIONS WAS SUCCESSFUL AND I RECEIVED A SQUAWK. THEY NEVER STATED THAT YOU ARE CLRED INTO THE ADIZ; YOU ARE TO 'ASSUME IT' FROM GETTING THE SQUAWK. I ONLY DISCOVERED THAT I HAD A PROB WHEN THE POTOMAC CTLR TOLD ME TO COPY A PHONE NUMBER AND BE SURE TO CALL THEM WHEN I WAS ON THE GND. THEY FELT I HAD 'VIOLATED THE ADIZ' ON DEP AND RETURN. WHAT CAN BE DONE TO PREVENT REOCCURRENCE OF THE ADIZ INFRACTIONS AND CONFUSIONS? THE BRIEFER SHOULD REMIND THE PLT OF THE EXIT POINTS OF THE ADIZ AND NOT THE FRZ DURING THE PREFLT FRZ FILING. THE CTLR LANGUAGE SHOULD BE CONSISTENT BTWN ARRS AND DEPS. ON ARR POTOMAC ALWAYS REMINDS YOU TO 'CHANGE TO ADVISORY FREQ; BUT STAY ON THE SQUAWK UNTIL YOU ARE ON THE GND.' ON DEP THEY SHOULD REMIND PLTS WITH SIMILAR LANGUAGE 'STAY ON THE SQUAWK UNTIL YOU ARE CLR OF THE ADIZ.' CLRLY IF THEY SEE YOU IN THE ADIZ AND YOU ARE TELLING THEM YOU ARE GOING TO SQUAWK 1200 THEY SHOULD REMIND YOU IN THE INTEREST OF SAFETY AND CONSISTENCY. AT NO TIME DID THEY DO THIS SINCE I WAS MONITORING THEIR FREQ. CTLRS SHOULD NOT BE HANDLING COMMERCIAL TFC INTO DCA AND VFR TFC BELOW THE CLASS B AIRSPACE AT THE SAME TIME. IF UNITED STATES SECURITY ACFT ARE OPERATING IN THE VICINITY OF THE ADIZ BOUNDARIES THEY SHOULD REMAIN WELL CLR AND AT A DIFFERENT ALT FROM VFR TFC. WHILE AT NO TIME DID I HAVE A VISUAL WITH THIS TFC; IT WAS VERY; VERY DISCONCERTING TO HAVE TO ADDRESS THIS POTENTIAL COLLISION THREAT ON MY TA SYS; RAISE THE CTLR; OBTAIN PERMISSION TO ENTER THE ADIZ; AND NAV IN MODERATE TURB. THE TFC COLLISION ADVISORIES SHOULD TRUMP ALL OTHER ISSUES. CLRNC INTO AND OUT OF THE ADIZ SHOULD HAVE SPECIFIC LANGUAGE WHICH IS STATED BY THE CTLR AND ACKNOWLEDGED BY THE PLT; JUST AS IT IS FOR CLASS B OR OTHER AIRSPACE. ON OTHER OCCASIONS I HAVE HEARD CTLRS HARSHLY ADMONISH PLTS FOR ASKING FOR CLRNC AFTER THEY GET A SQUAWK CODE. THIS INHIBITS FREE EXCHANGE OF INFO BTWN PLTS AND CTLRS; MAY CREATE A HOSTILE ATMOSPHERE AND CIRCUMSTANCES THAT COULD SET UP A SERIOUS MISHAP. CONSISTENT LANGUAGE ON CLRNCS SHOULD BE THE RULE.
