Abstract
A a flight instrument enabling a pilot to intercept and precisely follow a predefined GPS track. The instrument--known as a GPS steering indicator--provides a visual display which is similar in appearance to other aircraft instruments (and therefore instantly recognizable to nearly all pilots). However, the instrument is preferably differentiated somewhat in its visual appearance to convey to the pilot the fact that it displays steering commands rather than cross track error. An indicator needle deflects to instruct the pilot which way to turn and how much to turn in order to intercept and fly along a predefined GPS track. By centering the indicator needle, the pilot maintains the desired instantaneous track.
