Narrative:

En route from cle to pkb, we were cleared for descent into pkb. Operation was IFR, through ZID, and in cavu conditions. Due to a delay in the descent clearance, we arrived in the pkb area too high for the expected straight-in visual approach to runway 21. ZID terminated radar service at 6000 ft and instructed us to contact pkb tower, which issued a visual approach to runway 21 and to report 'crossing the river.' due to the altitude and proximity, I elected to make a descending 360 degree turn for position. After reporting the river inbound, tower asked if we had made a 360 degree to which I replied affirmative. After arrival I was requested to call the tower. While talking with the controller, a conference call to ind was established. Ind informed me that they had had traffic following me for pkb and that there could have been a possible conflict. Although we heard ind talking to other aircraft, we were never advised of any potential problem or even of any other area traffic. In retrospect, although I asked the first officer to inform the tower of the intended 360 degrees, I don't recall that transmission. Had ZID apprised us of the following traffic, we could have avoided the problem. This was a classic case of lack of communications on both parts. There was no close call, but the possibility existed.

Title: UNKNOWN CORPORATE ACFT WAS HIGH DUE TO LATE DSCNT CLRNC WHEN APCH CTLR TURNED FLC OVER TO TWR CTLR. TWR CTLR TOLD THEM CLRED FOR STRAIGHT-IN VISUAL AND TO RPT THE RIVER. BECAUSE THEY WERE HIGH RPTR CAPT DID A 360 DEG TURN FOR LOSS OF ALT, TWR QUESTIONED THEIR ACTION BECAUSE THERE WAS AN ACFT FOLLOWING THEM. TFC WAS UNKNOWN TO FLC.

Narrative: ENRTE FROM CLE TO PKB, WE WERE CLRED FOR DSCNT INTO PKB. OP WAS IFR, THROUGH ZID, AND IN CAVU CONDITIONS. DUE TO A DELAY IN THE DSCNT CLRNC, WE ARRIVED IN THE PKB AREA TOO HIGH FOR THE EXPECTED STRAIGHT-IN VISUAL APCH TO RWY 21. ZID TERMINATED RADAR SVC AT 6000 FT AND INSTRUCTED US TO CONTACT PKB TWR, WHICH ISSUED A VISUAL APCH TO RWY 21 AND TO RPT 'XING THE RIVER.' DUE TO THE ALT AND PROX, I ELECTED TO MAKE A DSNDING 360 DEG TURN FOR POS. AFTER RPTING THE RIVER INBOUND, TWR ASKED IF WE HAD MADE A 360 DEG TO WHICH I REPLIED AFFIRMATIVE. AFTER ARR I WAS REQUESTED TO CALL THE TWR. WHILE TALKING WITH THE CTLR, A CONFERENCE CALL TO IND WAS ESTABLISHED. IND INFORMED ME THAT THEY HAD HAD TFC FOLLOWING ME FOR PKB AND THAT THERE COULD HAVE BEEN A POSSIBLE CONFLICT. ALTHOUGH WE HEARD IND TALKING TO OTHER ACFT, WE WERE NEVER ADVISED OF ANY POTENTIAL PROB OR EVEN OF ANY OTHER AREA TFC. IN RETROSPECT, ALTHOUGH I ASKED THE FO TO INFORM THE TWR OF THE INTENDED 360 DEGS, I DON'T RECALL THAT XMISSION. HAD ZID APPRISED US OF THE FOLLOWING TFC, WE COULD HAVE AVOIDED THE PROB. THIS WAS A CLASSIC CASE OF LACK OF COMS ON BOTH PARTS. THERE WAS NO CLOSE CALL, BUT THE POSSIBILITY EXISTED.
