First Claim
Patent Images
1. An automatic control system for directional control of an aircraft moving on the ground, comprising:
- a pilot hand operable steering control input device for making directional control inputs;
manual steering command generation means for generating a nosewheel steering angle command from the pilot'"'"'s input to said hand operable steering control input device;
means for estimating lateral displacement of the aircraft from a desired taxi path;
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.

25. An automatic control system for directional control of an aircraft moving on the ground, comprising:
-
a pilot operable steering control input device for making large authority directional control inputs;
manual steering command generation means for generating a large steering authority nosewheel steering angle command from the pilot'"'"'s input to said steering control input device;
means for estimating lateral displacement of the aircraft from a desired taxi path, which desired taxi path may include turns requiring large steering authority for said aircraft to follow;
automatic steering command generation means for generating a large steering authority 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 large steering authority 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. - View Dependent Claims (26, 27, 28)

29. An automatic guidance system for aiding a pilot in precisely steering an aircraft moving on the ground comprising:
-
at least one pilot operable steering input device for making directional control inputs;
manual steering command generation means for generating a nosewheel steering angle command from the pilot'"'"'s input to said pilot operable steering control input device;
nosewheel steering control means for positioning the nosewheel steering so as to follow the nosewheel steering angle command from the manual steering command generation means;
means for estimating displacement of the aircraft from a desired taxi path and for generating a lateral displacement signal indicative of said lateral displacement;
automatic steering command generation means for generating a steering guidance command signal using said lateral displacement signal as an input; and
steering command display means for displaying said steering guidance command signal to the pilot and for aiding the pilot in precisely steering the aircraft along said desired taxi path. - View Dependent Claims (30)

31. An automatic guidance system for directional control inputs;
-
a pilot operable steering control input device for making directional control inputs;
manual steering command generation means for generating a large steering authority nosewheel steering angle command from the pilot'"'"'s input to said steering control input device;
means for estimating lateral displacement of the aircraft from a desired taxi path, which desired taxi path may include turns requiring large steering authority for said aircraft to follow;
automatic steering command generation means for generating a large steering authority steering angle command display for aiding the pilot in controlling the directional path of the aircraft so as to tend to zero said lateral displacement; and
nosewheel steering control means for positioning the nosewheel steering so as to follow the large steering authority nosewheel steering angle command from the manual steering command generation means.
