摘要： A DC signal representative of the rotary position of a fine synchro altimeter is subtracted from a DC signal representative of the angular position of a coarse synchro altimeter so as to provide a coarse staircase, the step positions of which are accurately aligned with the fine altimeter transition from maximum to minimum altitude indication. This staircase is used to select corresponding voltages, stepwise fashion, which are precisely generated so as to generate a staircase in which the voltage levels, as well as the positioning of the steps, are extremely precise. The fine altimeter voltage is added to the precise staircase so as to generate a precise DC signal of altitude. The voltage outputs of the fine synchro altimeter are resolved to a smooth, linear voltage as the function of altitude by means of electronic resolution equipment employing an RC/CR bridge, the input signals of which are reversed for a range of shaft angles displaced from 0* and 360* rotation; angular and voltage biases are also provided in this signal conditioning.

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.
