Question 40Electricity & Electronics - 1st Asst/Chief

The correct answer is C) -5.0 VDC. According to the information provided in the illustrated adaptive digital steering control system functional block diagram and the listed system interface signals table, for a rudder order of 20 degrees left rudder, the rudder order signal output voltage to the rudder servo amplifier would be -5.0 VDC. This is because left rudder signals are indicated as having a negative polarity, and a 20 degree left rudder order corresponds to a -5.0 VDC signal. The other options are incorrect because: A) -2.25 VDC is not the correct voltage for a 20 degree left rudder order. B) -4.0 VDC is not the correct voltage for a 20 degree left rudder order. D) +5.0 VDC would be the voltage for a 20 degree right rudder order, not a left rudder order.
