Narrative:

During climb out, departure gave us a climb from our initial altitude (5000 ft, I believe) and a turn from 270 degrees to 340 degrees. I was flying first officer giving a line check to a captain requalifying on the aircraft. The outside air temperature was low and we had the larger -15 type engines. Hence, our climb rate was much greater than normal. The captain became focused on maintaining a climb speed under 250 KIAS, and missed the turn given by ATC. Climbing above 8500 ft we received an RA and spotted a dash 8 ahead. Called ATC with traffic in sight. It was then that we realized we hadn't turned. The cause in this case was a common one. 2 pilots, each in seats they weren't 100% proficient in. A distraction for one that distracted the other (me). Lesson learned -- keep flying the airplane.

Narrative: DURING CLBOUT, DEP GAVE US A CLB FROM OUR INITIAL ALT (5000 FT, I BELIEVE) AND A TURN FROM 270 DEGS TO 340 DEGS. I WAS FLYING FO GIVING A LINE CHK TO A CAPT REQUALIFYING ON THE ACFT. THE OUTSIDE AIR TEMP WAS LOW AND WE HAD THE LARGER -15 TYPE ENGS. HENCE, OUR CLB RATE WAS MUCH GREATER THAN NORMAL. THE CAPT BECAME FOCUSED ON MAINTAINING A CLB SPD UNDER 250 KIAS, AND MISSED THE TURN GIVEN BY ATC. CLBING ABOVE 8500 FT WE RECEIVED AN RA AND SPOTTED A DASH 8 AHEAD. CALLED ATC WITH TFC IN SIGHT. IT WAS THEN THAT WE REALIZED WE HADN'T TURNED. THE CAUSE IN THIS CASE WAS A COMMON ONE. 2 PLTS, EACH IN SEATS THEY WEREN'T 100% PROFICIENT IN. A DISTR FOR ONE THAT DISTRACTED THE OTHER (ME).
