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, assuming left rudder signals are negative and right order signals are positive in polarity? Illustration EL-0191
AI Explanation
The correct answer is C) +3.75 VDC.
According to the information provided in the illustration and system interface signals table, a rudder order of 15 degrees right rudder would correspond to a positive voltage output signal of +3.75 VDC to the rudder servo amplifier. This is because the system uses a linear relationship between the rudder order angle and the output voltage, where left rudder orders are negative and right rudder orders are positive in polarity.
The other options are incorrect because -1.33 VDC would represent a left rudder order, -3.75 VDC would be too large of a negative voltage for a 15-degree right rudder order, and +5.0 VDC would be an excessively high voltage output signal.
