As shown in figure "A" of the illustration, fine adjustments such as "rate of turn signal" have no effect on steering stand operation when the 'operation selector switch' is in what position? Illustration EL-0097

Correct Answer: Option D — NFU

Non-Follow-Up (NFU) steering mode bypasses all feedback units and automatic inputs such as rate of turn signals. Direct momentary contact switches control the steering gear solenoid valves independently, rendering fine adjustments ineffective as specified in 46 CFR Subchapter J steering control system requirements.
