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 15 degrees right 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: +3.75 VDC. Proportional scaling of rudder order signals in adaptive digital steering systems utilizes defined voltage-per-degree conversion ratios. With a standard scale of plus or minus 5.0 VDC representing maximum helm, a 15-degree right (positive) rudder order produces exactly +3.75 VDC at the servo amplifier input.
