INADVERTENTLY ENTERED THE TCA.

Narrative

I CALLED DULLES APCH ON THE TELEPHONE TO ADVISE THEM I WAS PLANNING TO BE IN THEIR AREA BTWN THE TIME OF XC:30- XD:00. THE FACILITY MGR STATED HE DIDN'T ANTICIPATE ANY PROBLEM WITH ME TO BE IN THE AREA AT THAT TIME TO DO AERIAL PHOTOGRAPHY. HE SAID TO CALL DULLES APCH ON 124.65. AT APPROX XC:45; I CALLED DULLES APCH ON 124.65. I WAS ABOUT 13-15 MI N OF BROOKE VOR AT 2500 FT ON THE 05 DEG RADIAL OF BROOKE. DULLES APCH GAVE ME ANOTHER FREQ TO CALL. I CALLED DULLES AND STATED I WAS ON AN AERIAL PHOTOGRAPHY MISSION. THE CTLR STATED DUE TO TFC; SHE WAS TOO BUSY TO HANDLE MY REQUEST. I STATED THAT I HAD CALLED AT XA00 AM; TALKED TO THE MGR THAT I'D BE IN THE AREA TO DO AERIAL PHOTOGRAPHY. SHE CAME BACK SAYING 'DO NOT ENTER THE TCA; TOO BUSY TO HANDLE MY REQUEST.' I CHKED MY CHART. I SAW I WAS STILL UNDER THE 2500-10000 FT RING. I PROCEEDED TO THE EDGE OF THE 1500 FT RING UNDERSTANDING THAT I WAS STILL BELOW THE TCA. 'IDENT' THE CTLR SAID; YOU HAVE VIOLATED THE TCA. SAID I WAS MAKING A 180 DEG SBOUND TURN. SHE THEN GAVE ME A CODE TO SQUAWK AND SAID TO PROCEED TO THE SITE. I DID NOT INTEND TO VIOLATE THE TCA. I WOULD SUGGEST THE CTLR GIVE THE PLT A SPECIFIC LOCATION TO CIRCLE UNTIL SHE/HE CAN GIVE CLRNC TO ENTER AND PROCEED OR GIVE A SPECIFIC TIME TO THE PLT TO LET HIM/HER KNOW HOW MUCH TIME TO WAIT. WHEN THE CTLR SAYS 'TFC DOES NOT PERMIT' DOES NOT HAVE SPECIFIC MEANING TO THE PLT.
