I seem to recall that , like other types, on the 767 the autobrakes will not activate until the pitch attitude is at or less than 1 degree nose up, i.e. you must derotate upon mainwheel touch down.One effect of this is that other inputs, pilot not relaxing the back pressure, spoiler activation, reverser deployment etc etc may cause the pitch attitude to INCREASE or cause a pitch up if the lowering of the nose by the PF is not applied in a timely fashion.Not all FCOMs contain the reference to the 1 degree requirement.Im unsure why that is.
