Narrative:

Airlines flight departing anc made turn out in wrong direction. Cleared knik 3 departure but instead executed anc 9 departure. Problem discovered on departure control. Aircraft placed on radar vector for climb. No evasive action required. No air traffic conflict. Contributing factors: 1) previous connecting flight with same crew arrived late in anc due to gate hold at sea. This delay in conjunction with aircraft change in anc cut short normal turnaround time. 2) departure clearance received by captain and first officer while I, as second officer on large transport, was copying load data and preparing takeoff data card. Confusion caused by tower several times clearing our takeoff on 32 where winds would have been nearly out of limits for tailwinds. Our aircraft had to insist on runway 6 departure. Knik 3 departure for runway 6 is very unusual. Normal departure is anc 9. Conclusion: shortened turnaround time, my being unable to monitor departure clearance and the very unusual clearance on a knik 3 SID from runway 6 all contributed to incorrect turn out. If I had heard the departure clearance I could have queried the crew on the proper SID.

Title: HEADING TRACK ROUTE DEVIATION ON SID.

Narrative: AIRLINES FLT DEPARTING ANC MADE TURN OUT IN WRONG DIRECTION. CLRED KNIK 3 DEP BUT INSTEAD EXECUTED ANC 9 DEP. PROB DISCOVERED ON DEP CTL. ACFT PLACED ON RADAR VECTOR FOR CLB. NO EVASIVE ACTION REQUIRED. NO AIR TFC CONFLICT. CONTRIBUTING FACTORS: 1) PREVIOUS CONNECTING FLT WITH SAME CREW ARRIVED LATE IN ANC DUE TO GATE HOLD AT SEA. THIS DELAY IN CONJUNCTION WITH ACFT CHANGE IN ANC CUT SHORT NORMAL TURNAROUND TIME. 2) DEP CLRNC RECEIVED BY CAPT AND F/O WHILE I, AS S/O ON LGT, WAS COPYING LOAD DATA AND PREPARING TKOF DATA CARD. CONFUSION CAUSED BY TWR SEVERAL TIMES CLRING OUR TKOF ON 32 WHERE WINDS WOULD HAVE BEEN NEARLY OUT OF LIMITS FOR TAILWINDS. OUR ACFT HAD TO INSIST ON RWY 6 DEP. KNIK 3 DEP FOR RWY 6 IS VERY UNUSUAL. NORMAL DEP IS ANC 9. CONCLUSION: SHORTENED TURNAROUND TIME, MY BEING UNABLE TO MONITOR DEP CLRNC AND THE VERY UNUSUAL CLRNC ON A KNIK 3 SID FROM RWY 6 ALL CONTRIBUTED TO INCORRECT TURN OUT. IF I HAD HEARD THE DEP CLRNC I COULD HAVE QUERIED THE CREW ON THE PROPER SID.
