A DEP DC9 EXPERIENCES A POTENTIAL CONFLICT WITH A XING B727 AT 5000 FT. FO; PF; HAD DELAYED THE TURN TO 130 DEGS FROM 170 DEGS DUE TO A MISINTERP OF THE DEP CTLR'S INSTRUCTIONS. AN IMMEDIATE TURN TO 130 DEGS WOULD HAVE PROVIDED ADEQUATE SEPARATION FROM THE B727.

Narrative

PRIOR TO DEP; WE DISCUSSED DEP PROCS FOR CYWG 2 DEP AT WINNIPEG; INCLUDING TURN AT 3.5 DME TO 170 DEGS (RWY 18 WAS IN USE). AFTER NORMAL TKOF; WE CHKED IN WITH YWG DEP CTLR WHO INSTRUCTED US TO TURN L TO 130 DEGS AT 6 MI. WE BOTH TOOK THAT TO MAINTAIN RWY HDG TILL 6 MI AND THEN TO THE NEW HDG. AS WE APCHED 6 NM AND BEGAN THE L TURN TO 130 DEGS; I SAW A B727 ON THE NOSE TO 1 O'CLOCK MOVING RAPIDLY FROM L TO R SLIGHTLY BELOW OUR ALT. ALMOST IMMEDIATELY AFTER SIGHTING THE B727 VISUALLY; THE TCASII ISSUED A TA. AT THAT TIME OUR ACFT WAS COMING L OF THE B727'S EXTENDED 5 O'CLOCK POS. WE CONTINUED IN THAT DIRECTION WITH THE SAME 1300-1500 FPM CLB RATE. WE RECEIVED 1 RA CALL TO 'MAINTAIN VERT AIRSPD' WHICH WE DID. ONLY AFTER THE RA DID WE RECEIVE ANY CALL FROM YWG DEP CTL IN REGARD TO THE B727 TFC. THE RA HAD THE GREEN BAND BTWN 1000-1500 FPM CLB. AT THAT TIME OUR CLB RATE WAS 1300-1500 FPM. THE B727 INDICATED THAT THEY HAD RECEIVED A TCASII ALERT. I DO NOT RECALL IF THEY INDICATED A TA OR RA. THE B727 WAS ANOTHER ACR. WE CONTINUED TO JOIN THE OUTBOUND RADIAL. CANADIAN CTLRS USE SLIGHTLY DIFFERENT TERMINOLOGY AND I DO NOT RECALL THE EXACT PHRASE USED; BUT BOTH PLTS TOOK THE INSTRUCTION TO BE MAINTAIN RWY HDG TO 6 NM AND THEN TURN ON TO 130 DEGS AND JOIN THE OUTBOUND RADIAL.
