What coordinates are displayed on a range-height indicator (RHI) scope?

The correct answer focuses on how a range-height indicator (RHI) scope is designed to represent information in a specific format that is crucial for interpreting radar data in three dimensions. A RHI scope provides altitude information by displaying the range (distance from the radar site) on the horizontal axis and the height (altitude) of targets on the vertical axis.

This representation allows operators to visualize the vertical structure of targets, such as weather phenomena or aircraft, which is essential for tasks like navigation and weather forecasting. By providing altitude information, the RHI helps technicians and operators understand how various elements are positioned in the atmosphere, thus aiding in decision-making processes based on this three-dimensional data. The expected use of RHI in radar operations highlights the significance of altitude in relation to distance, ensuring safe and effective situational awareness.
