What controls rudder movement when the Operation Selector Switch shown in figure "A" of the illustration is in the "Controller" position? Illustration EL-0097

Correct Answer: Option B — non-follow-up controller

The Controller position designates the Non-Follow-Up (NFU) mode of operation. In accordance with IEEE 45 and 46 CFR guidelines, rudder movement is directly commanded via manual directional toggle switches that energize hydraulic solenoid valves without automatic feedback loop positioning.
