According to 46 CFR §58.25-5, which of the following correctly defines 'full followup control' of a steering gear?
- A. A system in which the rudder moves continuously in the commanded direction until manually stopped by the operator.
- ✓ Closed-loop (feedback) control that relates the position of the helm to a specific rudder angle and automatically stops the rudder when the selected angle is reached.Correct
- C. A non-followup control system that transmits helm orders to the power actuating system without feedback.
- D. Any control system that allows the rudder to be moved from the pilothouse by mechanical, hydraulic, or electrical means.
Why B is correct
46 CFR §58.25-5(a) defines full followup control as closed-loop (feedback) control that relates the helm position to a specific rudder angle, transmitting the helm-angle order to the power actuating system and automatically stopping the rudder when the selected angle is reached. A non-followup system lacks this feedback loop.
