🔍 Key Concepts

• Trace the signal path from the Operation (Operating Mode) Selector Switch in figure A when it is set to the Controller position • Difference between follow-up (steering wheel / gyro) control and non-follow-up (NFU) control • How the rudder power unit receives its control signal in each mode shown in the block diagram

💭 Think About

• When the selector is on Controller, which block in the diagram is directly feeding the signal to the port and starboard amplifiers that drive the power units? • Look at the switch contacts drawn around the Operating Mode Selector Switch: which line is actually connected in the Controller position, and what device is drawn at the other end of that line? • Which of the answer choices is clearly shown in the diagram as the active control element for rudder movement in that switch position, rather than just providing a reference or feedback signal?

✅ Before You Answer

• Follow the solid line from the Controller position of the selector to see which labeled box it connects to • Confirm whether the steering wheel signal is bypassed or routed through another unit when in Controller mode • Verify that the chosen device is explicitly connected to the power unit control signal path that drives rudder movement in figure A
