Narrative:

I was captain giving IOE training to first officer who was PF. Wind condition at takeoff was strong crosswind about 70 degrees off nose, with windshear reported. First officer was extensively briefed on specialized technique required for handling takeoff roll, rotation, and initial climb out in strong crosswind (unusual takeoff roll rudder input, wings level rotation to clear engine pods, and prompt turn into wind after positive rate established). Nevertheless, upwind wing was to rise (about 7 degree bank angle) shortly after aircraft airborne, causing an aircraft displacement just outside runway edge. Aircraft was returned to runway boundary by runway end. As instructor, I should have immediately provided aileron input to remove the inadvertent bank and flown the aircraft back to centerline, instead of waiting for first officer to do it. There was a moment of hesitation and surprise on my part at this deviation, since this first officer had already demonstrated excellent knowledge, flying skills, and situational awareness, but this takeoff was asking a lot from a student just coming into the seat after several yrs as a flight engineer. This shows me that I have to be more positively 'at the ready' for intervention, regardless of the quality of the other flying crew member at the controls.

Original NASA ASRS Text

Title: B747 CREW HAD RWY EXCURSION IN A XWIND DEPARTING VHHH.

Narrative: I WAS CAPT GIVING IOE TRAINING TO FO WHO WAS PF. WIND CONDITION AT TKOF WAS STRONG XWIND ABOUT 70 DEGS OFF NOSE, WITH WINDSHEAR RPTED. FO WAS EXTENSIVELY BRIEFED ON SPECIALIZED TECHNIQUE REQUIRED FOR HANDLING TKOF ROLL, ROTATION, AND INITIAL CLBOUT IN STRONG XWIND (UNUSUAL TKOF ROLL RUDDER INPUT, WINGS LEVEL ROTATION TO CLR ENG PODS, AND PROMPT TURN INTO WIND AFTER POSITIVE RATE ESTABLISHED). NEVERTHELESS, UPWIND WING WAS TO RISE (ABOUT 7 DEG BANK ANGLE) SHORTLY AFTER ACFT AIRBORNE, CAUSING AN ACFT DISPLACEMENT JUST OUTSIDE RWY EDGE. ACFT WAS RETURNED TO RWY BOUNDARY BY RWY END. AS INSTRUCTOR, I SHOULD HAVE IMMEDIATELY PROVIDED AILERON INPUT TO REMOVE THE INADVERTENT BANK AND FLOWN THE ACFT BACK TO CTRLINE, INSTEAD OF WAITING FOR FO TO DO IT. THERE WAS A MOMENT OF HESITATION AND SURPRISE ON MY PART AT THIS DEV, SINCE THIS FO HAD ALREADY DEMONSTRATED EXCELLENT KNOWLEDGE, FLYING SKILLS, AND SITUATIONAL AWARENESS, BUT THIS TKOF WAS ASKING A LOT FROM A STUDENT JUST COMING INTO THE SEAT AFTER SEVERAL YRS AS A FE. THIS SHOWS ME THAT I HAVE TO BE MORE POSITIVELY 'AT THE READY' FOR INTERVENTION, REGARDLESS OF THE QUALITY OF THE OTHER FLYING CREW MEMBER AT THE CTLS.
