Narrative:

After takeoff, turned to heading 270 degrees as briefed before takeoff. I was under the impression (false) we had been assigned jacky departure. First officer had picked up beggo departure calling for 240 degree heading. He confirmed 270 degree heading. ATC asked for our heading after being assigned climb to 4000 ft. It was then we learned we were flying incorrect departure. In retrospect CRM broke down during the takeoff briefing. I should have asked which departure we were cleared for. First officer was new (less than 40 hours) and assumed that I knew the 270 degree heading was the correct one. Takeoff briefs will now include the full SID! Supplemental information from acn 343370: I do believe that the density of traffic on the radio, and our hurried situation, played a role.

Original NASA ASRS Text

Title: ATR72 FLC NON ADHERENCE TO ATC CLRNC, HDG TRACK POS DEV.

Narrative: AFTER TKOF, TURNED TO HDG 270 DEGS AS BRIEFED BEFORE TKOF. I WAS UNDER THE IMPRESSION (FALSE) WE HAD BEEN ASSIGNED JACKY DEP. FO HAD PICKED UP BEGGO DEP CALLING FOR 240 DEG HDG. HE CONFIRMED 270 DEG HDG. ATC ASKED FOR OUR HDG AFTER BEING ASSIGNED CLB TO 4000 FT. IT WAS THEN WE LEARNED WE WERE FLYING INCORRECT DEP. IN RETROSPECT CRM BROKE DOWN DURING THE TKOF BRIEFING. I SHOULD HAVE ASKED WHICH DEP WE WERE CLRED FOR. FO WAS NEW (LESS THAN 40 HRS) AND ASSUMED THAT I KNEW THE 270 DEG HDG WAS THE CORRECT ONE. TKOF BRIEFS WILL NOW INCLUDE THE FULL SID! SUPPLEMENTAL INFO FROM ACN 343370: I DO BELIEVE THAT THE DENSITY OF TFC ON THE RADIO, AND OUR HURRIED SIT, PLAYED A ROLE.
