The original question is made due to the lack of info about recomended modes for a Autothrottle inoperative take off. For Boeing 767 there’s is not a supplementary or bulletin regarding this. What I do is at 400’ HDG or LNAV, at acceleration altitude, ask for Climb Power in TMC, Speed at CMS or 250 kts, clean up flaps, and then flight level change or VNAV (maybe it will engage in VNAV SPEED), then Autopilot and climb with 10° pitch…..FCOM does not say too much about VNAV or its relationship with Autothrottle
