Narrative:

The flight plan from atl to mco was atl-soone-mcn-J45-amg- LEESE7-mco which is slightly different than the normal preferred route of J89-otk-LEESE7-mco because of slightly better winds and the resultings. We discussed the change and loaded the FMS with this planned route prior to the flight and received a pre departure clearance with clearance for that routing. After takeoff, departure control gave us a final heading of 1760 degrees and turned us over to ZTL. The controller gave us a climb to FL240 and a turn to 180 degrees to intercept J89. This is a standard procedure and terminology used for this direction departures. Soone is a sbound departure fix 35 mi south of atl on J89. The intercept heading given by the controller intercepted J89 just prior to soone and at soone we turned direct mcn (heading 129 degrees) as per our clearance. We were climbing through FL210 and TCASII displayed a target at our 10 O'clock position, FL210 and 10 mi. My copilot asked the controller about our heading and she immediately asked us to accelerate through FL220 and turn right to 180 degrees. She said that we had traffic at FL210 and 5 mi. The closest we showed the target was about 7 mi. After a brief pause, she asked what our last clearance was and we told her the pre departure clearance soone-mcn-J45 routing.she then gave us a new clearance of heading 180 degrees to intercept J89, J89-otk-LEESE7-mco. The copilot read back that clearance and we proceeded on that route for an uneventful flight. I don't know exactly why this incident occurred. I feel that we followed the proper procedure by continuing with our cleared routing after soone since no further clearance was given after intercepting J89. I feel sure that the controller was expecting us to continue on J89 as the flts normally do and which is the preferred route. I was probably negligent in not questioning the controllers intentions after soone since our clearance was not over the usual route but I did not think of that at the time. Next time I will probably ask.

Title: OP DEV.

Narrative: THE FLT PLAN FROM ATL TO MCO WAS ATL-SOONE-MCN-J45-AMG- LEESE7-MCO WHICH IS SLIGHTLY DIFFERENT THAN THE NORMAL PREFERRED RTE OF J89-OTK-LEESE7-MCO BECAUSE OF SLIGHTLY BETTER WINDS AND THE RESULTINGS. WE DISCUSSED THE CHANGE AND LOADED THE FMS WITH THIS PLANNED RTE PRIOR TO THE FLT AND RECEIVED A PDC WITH CLRNC FOR THAT RTING. AFTER TKOF, DEP CTL GAVE US A FINAL HDG OF 1760 DEGS AND TURNED US OVER TO ZTL. THE CTLR GAVE US A CLB TO FL240 AND A TURN TO 180 DEGS TO INTERCEPT J89. THIS IS A STANDARD PROC AND TERMINOLOGY USED FOR THIS DIRECTION DEPS. SOONE IS A SBOUND DEP FIX 35 MI S OF ATL ON J89. THE INTERCEPT HDG GIVEN BY THE CTLR INTERCEPTED J89 JUST PRIOR TO SOONE AND AT SOONE WE TURNED DIRECT MCN (HDG 129 DEGS) AS PER OUR CLRNC. WE WERE CLBING THROUGH FL210 AND TCASII DISPLAYED A TARGET AT OUR 10 O'CLOCK POS, FL210 AND 10 MI. MY COPLT ASKED THE CTLR ABOUT OUR HDG AND SHE IMMEDIATELY ASKED US TO ACCELERATE THROUGH FL220 AND TURN R TO 180 DEGS. SHE SAID THAT WE HAD TFC AT FL210 AND 5 MI. THE CLOSEST WE SHOWED THE TARGET WAS ABOUT 7 MI. AFTER A BRIEF PAUSE, SHE ASKED WHAT OUR LAST CLRNC WAS AND WE TOLD HER THE PDC SOONE-MCN-J45 RTING.SHE THEN GAVE US A NEW CLRNC OF HDG 180 DEGS TO INTERCEPT J89, J89-OTK-LEESE7-MCO. THE COPLT READ BACK THAT CLRNC AND WE PROCEEDED ON THAT RTE FOR AN UNEVENTFUL FLT. I DON'T KNOW EXACTLY WHY THIS INCIDENT OCCURRED. I FEEL THAT WE FOLLOWED THE PROPER PROC BY CONTINUING WITH OUR CLRED RTING AFTER SOONE SINCE NO FURTHER CLRNC WAS GIVEN AFTER INTERCEPTING J89. I FEEL SURE THAT THE CTLR WAS EXPECTING US TO CONTINUE ON J89 AS THE FLTS NORMALLY DO AND WHICH IS THE PREFERRED RTE. I WAS PROBABLY NEGLIGENT IN NOT QUESTIONING THE CTLRS INTENTIONS AFTER SOONE SINCE OUR CLRNC WAS NOT OVER THE USUAL RTE BUT I DID NOT THINK OF THAT AT THE TIME. NEXT TIME I WILL PROBABLY ASK.
