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, assuming left rudder signals are negative and right order signals are positive in polarity? Illustration EL-0191
AI Explanation
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.
