Narrative:

Received clearance to operate within the washington class B from dulles TRACON. Was assigned headings and vectored around the east side of iad. Handed off to washington TRACON who continued to assign headings. Winds were computed to be approximately 250FT at 69 KTS. Assigned heading of 190 degrees resulted in ground track of 165 degrees. Washington assigned new headings as needed. Became concerned about position relative to the washington 15 NM tfr. Tuned me to dca and noted position was 15.1 NM. Adjusted heading but not before reaching 14.8 NM DME. At no time did dca TRACON issue any advisory or warning about encroaching on the tfr. No doubt the strong winds contributed to this. I should have been paying more attention to the tfr boundary. But operating in class B airspace and receiving assigned headings and altitudes provided a false sense of assured tfr avoidance. Operating VFR outside of class B airspace and receiving flight following, ATC is very proactive in providing instructions to avoid other active restr airspace.

Title: A C180 PLT VIOLATED THE DCA TFR.

Narrative: RECEIVED CLRNC TO OPERATE WITHIN THE WASHINGTON CLASS B FROM DULLES TRACON. WAS ASSIGNED HEADINGS AND VECTORED AROUND THE E SIDE OF IAD. HANDED OFF TO WASHINGTON TRACON WHO CONTINUED TO ASSIGN HEADINGS. WINDS WERE COMPUTED TO BE APPROX 250FT AT 69 KTS. ASSIGNED HEADING OF 190 DEGS RESULTED IN GND TRACK OF 165 DEGS. WASHINGTON ASSIGNED NEW HEADINGS AS NEEDED. BECAME CONCERNED ABOUT POS RELATIVE TO THE WASHINGTON 15 NM TFR. TUNED ME TO DCA AND NOTED POS WAS 15.1 NM. ADJUSTED HEADING BUT NOT BEFORE REACHING 14.8 NM DME. AT NO TIME DID DCA TRACON ISSUE ANY ADVISORY OR WARNING ABOUT ENCROACHING ON THE TFR. NO DOUBT THE STRONG WINDS CONTRIBUTED TO THIS. I SHOULD HAVE BEEN PAYING MORE ATTN TO THE TFR BOUNDARY. BUT OPERATING IN CLASS B AIRSPACE AND RECEIVING ASSIGNED HEADINGS AND ALTS PROVIDED A FALSE SENSE OF ASSURED TFR AVOIDANCE. OPERATING VFR OUTSIDE OF CLASS B AIRSPACE AND RECEIVING FLT FOLLOWING, ATC IS VERY PROACTIVE IN PROVIDING INSTRUCTIONS TO AVOID OTHER ACTIVE RESTR AIRSPACE.
