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.
