Narrative
WHILE HOLDING IN POSITION ON RUNWAY, ATC ISSUED MODIFIED TAKEOFF CLEARANCE TO TURN RIGHT HEADING 010 AND CLIMB TO 2,000 FEET AFTER TAKEOFF AS OPPOSED TO RUNWAY HEADING 3,000. AFTER TAKING OFF IN VMC CONDITIONS, AS BRIEFED, THE CAPTAIN (PF (PILOT FLYING)) INITIATED A RIGHT TURN TO 010. CLIMBING THROUGH 1600 WE RECEIVED A "TRAFFIC TRAFFIC" WARNING FROM TCAS. CONCURRENTLY ATC ADVISED US OF THE TRAFFIC BUT DID NOT ISSUE AN ALERT. WE HAD VISUAL CONTACT WITH THE TRAFFIC AT THAT POINT. THROUGH 1700, THE RESOLUTION ADVISORY STARTED, SAYING "LEVEL OFF LEVEL OFF". THE CAPTAIN LEVELED OFF AT 2000 AND ROLLED OUT ON HEADING 010. I ADVISED ATC THAT WE WERE COMPLYING WITH A TCAS RESOLUTION ADVISORY AND WERE LEVEL. THE TRAFFIC PASSED APPROXIMATELY 500 FT. ABOVE FROM LEFT TO RIGHT, AND TCAS ANNOUNCED CLEAR OF CONFLICT. I ADVISED ATC WE WERE CLEAR OF CONFLICT AND THEY ISSUED A CLIMB TO 10,000 FT. ON THE SAME HEADING, ENDING THE EVENT.
AS FAR AS WE COULD TELL, ATC COULD HAVE CLEARED US FOR TAKEOFF STRAIGHT OUT AND THEN TURNED US BEHIND THE TRAFFIC.
GIVEN OUR DEPARTURE OFF OF RUNWAY 28 AND OUR INITIAL FIX OF JROSS, WHICH WAS NEARLY THE OPPOSITE DIRECTION, ATC MAY HAVE BEEN TRYING TO GIVE US A SHORTCUT BY MODIFYING OUR CLIMB CLEARANCE TO 2,000 INSTEAD OF 3,000 SO THEY COULD IMMEDIATELY TURN US CLOSER TO JROSS. IT IS UNCLEAR WHETHER THE CONTROLLER PLANNED FOR US TO TURN INSIDE OR OUTSIDE OF THE TRAFFIC, HOWEVER WE ENDING UP GOING NEARLY RIGHT UNDER THE TRAFFIC, AND SEEMINGLY WITH LESS THAN REQUIRED VERTICAL SEPARATION. THIS CONFLICT WAS UNAVOIDABLE GIVEN THE CLEARANCE RECEIVED.
END REPORT
