Radar equipment and speed of rotation indicator ... The radar screen must not be substantially off the steersman's line of vision when he is in the normal position at the wheel.
On vessels for inland waterways the rate-of-turn indicator has the task of assisting radar navigation by measuring and indicating the swing (rate of turn) of the ship to port and starboard. In conjunction with course-keeping devices (autopilot) the rate gyro, as sensor system, provides the turning rate reference. On seagoing ships, the rate-of-turn indicator serves primarily as a navigating support for sensing and indicating swing.
