As shown in the illustrated adaptive digital steering control system functional block diagram and listed system interface signals table, what would the rudder order signal output voltage to the rudder servo amplifier be for a rudder order of 20 degrees left rudder? Assume that left rudder order signals are negative in polarity and that right rudder order signals are positive in polarity. EL-0191

Accepted Answer

Option C: -5.0 VDC. Adaptive digital steering systems convert directional rudder commands into proportional analog control voltages. Assuming a full-scale range where maximum rudder angle corresponds to 5.0 VDC, a 20-degree left rudder order generates a negative polarity signal reaching the maximum threshold of -5.0 VDC.
