Narrative:

Class B airspace disagreement! While tracking the 060 radial off of talladega, al, and 35 DME west of atlanta: working ZTL for flight following all the way from talladega, al, to greenville, sc, and on a center transponder squawk, ZTL terminated my service. ZTL said remain clear of class B airspace. Immediately, I contacted atlanta approach and was told to turn 20 degrees left and remain clear of class B airspace. When I asked why. Atlanta approach said I was already in class B airspace, then I disagreed. I stated that according left 13 and 14, 19 and 20 charts that the talladega 060 radial and 35 DME west of atlanta was outside of class B airspace and if this is incorrect that the left 13 and 14, 19 and 20 charts need to be changed. Atlanta approach agreed. Recommendations: if left 13 and 14, 19 and 20 low altitude charts are incorrect, they need to be changed in order to prevent class B conflicts. Also, whenever full route flight following is in use, especially near class B airspace, service should not be terminated! And if the left 13 and 14, 19 and 20 low altitude charts are incorrect, then ZTL should not have allowed me into class B airspace, terminated service, and then ask that I remain clear of class B airspace. Callback conversation with reporter revealed the following information: reporter states he was on centerline of 060 radial and tuned into atl DME when told he was within the class B airspace. Controller stated 33 DME and reporter showed 35 DME. Analyst pointed out that class B boundary is 35 mi. Reporter agreed, but felt that since he was on flight following and no mention was made of any class B penetration until he was dumped from radar service, ATC should have informed him previous to terminating radar service. Reporter had quite a conversation with the next controller who vectored him out of the airspace and who acknowledged that ATC sometimes gets busy and just drops the service. Since this was in a busy arrival corridor, reporter was all the more astonished to be terminated. He felt he should have been given some warning of radar service terminating.

Title: UNAUTH PENETRATION OF CLASS B AIRSPACE.

Narrative: CLASS B AIRSPACE DISAGREEMENT! WHILE TRACKING THE 060 RADIAL OFF OF TALLADEGA, AL, AND 35 DME W OF ATLANTA: WORKING ZTL FOR FLT FOLLOWING ALL THE WAY FROM TALLADEGA, AL, TO GREENVILLE, SC, AND ON A CTR XPONDER SQUAWK, ZTL TERMINATED MY SVC. ZTL SAID REMAIN CLR OF CLASS B AIRSPACE. IMMEDIATELY, I CONTACTED ATLANTA APCH AND WAS TOLD TO TURN 20 DEGS L AND REMAIN CLR OF CLASS B AIRSPACE. WHEN I ASKED WHY. ATLANTA APCH SAID I WAS ALREADY IN CLASS B AIRSPACE, THEN I DISAGREED. I STATED THAT ACCORDING L 13 AND 14, 19 AND 20 CHARTS THAT THE TALLADEGA 060 RADIAL AND 35 DME W OF ATLANTA WAS OUTSIDE OF CLASS B AIRSPACE AND IF THIS IS INCORRECT THAT THE L 13 AND 14, 19 AND 20 CHARTS NEED TO BE CHANGED. ATLANTA APCH AGREED. RECOMMENDATIONS: IF L 13 AND 14, 19 AND 20 LOW ALT CHARTS ARE INCORRECT, THEY NEED TO BE CHANGED IN ORDER TO PREVENT CLASS B CONFLICTS. ALSO, WHENEVER FULL RTE FLT FOLLOWING IS IN USE, ESPECIALLY NEAR CLASS B AIRSPACE, SVC SHOULD NOT BE TERMINATED! AND IF THE L 13 AND 14, 19 AND 20 LOW ALT CHARTS ARE INCORRECT, THEN ZTL SHOULD NOT HAVE ALLOWED ME INTO CLASS B AIRSPACE, TERMINATED SVC, AND THEN ASK THAT I REMAIN CLR OF CLASS B AIRSPACE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES HE WAS ON CTRLINE OF 060 RADIAL AND TUNED INTO ATL DME WHEN TOLD HE WAS WITHIN THE CLASS B AIRSPACE. CTLR STATED 33 DME AND RPTR SHOWED 35 DME. ANALYST POINTED OUT THAT CLASS B BOUNDARY IS 35 MI. RPTR AGREED, BUT FELT THAT SINCE HE WAS ON FLT FOLLOWING AND NO MENTION WAS MADE OF ANY CLASS B PENETRATION UNTIL HE WAS DUMPED FROM RADAR SVC, ATC SHOULD HAVE INFORMED HIM PREVIOUS TO TERMINATING RADAR SVC. RPTR HAD QUITE A CONVERSATION WITH THE NEXT CTLR WHO VECTORED HIM OUT OF THE AIRSPACE AND WHO ACKNOWLEDGED THAT ATC SOMETIMES GETS BUSY AND JUST DROPS THE SVC. SINCE THIS WAS IN A BUSY ARR CORRIDOR, RPTR WAS ALL THE MORE ASTONISHED TO BE TERMINATED. HE FELT HE SHOULD HAVE BEEN GIVEN SOME WARNING OF RADAR SVC TERMINATING.
