FO FLYING MADE WRONG TURN DEPARTING UNK; AK. CAPT CORRECTED BACK ON COURSE.

Narrative

DEPARTED FROM UNK (UNALAKLEET) ARPT; FOLLOWING THE IFR DEP WHICH IS TO FLY OUTBOUND ON THE R-269 OF UNK VOR; THEN ON COURSE; TO CROSS THE VOR ABOVE 300 FT. DUE TO THE GUSTY WINDS AND MARGINAL RWY CONDITIONS; I ELECTED TO DO THE TKOF; AND THEN LET THE FO COMPLETE THE FLT. PRIOR TO TKOF WE HAD DISCUSSED THE DEP AND WHAT WE DO IN THE EVENT OF AN EMER. DUE TO THE MOUNTAINOUS TERRAIN E OF THE ARPT; IT IS NECESSARY TO PROCEED W; OVER THE OCEAN TO MANEUVER AS NECESSARY FOR THE DEP. AFTER TKOF FROM RWY 14; I TURNED R TO INTERCEPT THE R-269 UNK. UPON COMPLETING THE CLB CHKLIST; I LET THE FO TAKE THE ACFT; AT WHICH TIME HE STATED THAT WE WERE OUT OF 3000 TURNING DIRECT TO THE VOR. I CORRECTED HIM AND TOLD HIM TO INTERCEPT AND TRACK THE R-269. FO CONTINUED OUTBOUND UNTIL FL210; AT WHICH TIME WE REVERSED COURSE TO PROCEED E AS CLRED TO ANC (ANCHORAGE; AK). UPON DISCUSSING THE EVENT; WE BOTH DECIDED THAT I DIDN'T MAKE MYSELF CLR AS TO HOW I WANTED HIM TO COMPLETE THE DEP PROC. WE WERE BOTH TIRED FROM FLYING ALL DAY AND SHOULD HAVE BEEN MORE ATTENTIVE TO POSSIBLE ERRORS. IN THE FUTURE I WILL BE MORE EXPLICIT AS TO THE ACTIONS NECESSARY/EXPECTED FROM THE PNF DURING CRITICAL FLT PHASES. WHENEVER PNF TAKES THE CTLS FROM THE PF; HE SHOULD BE BRIEFED AND UNDERSTAND WHAT IS GOING ON AT THAT MOMENT -- ESPECIALLY SINCE THE PNF MAY BE OUT OF THE LOOP; AS IN THIS CASE; DOING CLB CHKLISTS.
