    摘要: Digital values of designated track angles for various portions of a preplanned flight are presented by a storage unit for different segments of the flight plan. These values are converted to quadrature square waves of a phase related to the designated track angle, which are used to synchronously demodulate sinusoidal signals of X and Y coordinates from the aircraft to a way point relating to the flight plan segment, the result being combined to provide along-track distance to way point and cross track error. The square wave signals may be used to drive a conventional differential resolver so as to automatically adjust the resolver to the designated track angle to provide an indication thereof; alternatively, a digital display of the stored value may be used.
