    means for estimating lateral displacement of the aircraft from a desired taxi path;

    said means for estimating lateral displacement comprising camera sensing;

    automatic steering command generation means for generating a nosewheel steering angle command which tends to zero said lateral displacement; and

    ,nosewheel steering control means for positioning the nosewheel steering so as to follow the nosewheel steering angle command from either the manual steering command generation means or the automatic steering command generation means depending on whether automatic ground steering is disengaged or engaged.
