As shown in the illustrated graph showing the effect of overshoot on steering system control stability, what statement is true? EL-0188 Illustration EL-0188: the U.S. Coast Guard has not released this illustration.

Correct Answer: Option D — The dead band is approximately 8 degrees and the control system is inherently unstable.

Control system stability analysis using overshoot graphs evaluates dead band limits and damping ratios. A dead band of approximately 8 degrees coupled with excessive hunting indicates that the steering control loop lacks sufficient damping, resulting in an inherently unstable oscillatory response.
