Don't set VNAV and LNAV before takeoff. Both should be off. This is a 1980's B767. At 400' AFE set LNAV on and then at 1500' AFE set either VNAV or FLCH. Power will reduce to CLB power. The correct way is to set FLCH and set speed to 220KIAS and then continue climbing to 3000' AFE while retracting flaps. AT 3000'AFE set VNAV.

Trevor - appreciate detailed description. Works well as u wrote, thank u
