What information does the Radio Magnetic Indicator (RMI) show?

The Radio Magnetic Indicator (RMI) is specifically designed to provide pilots with important navigational information related to their heading and the bearing to and from radio navigation aids, such as VOR (VHF Omnidirectional Range) stations. The RMI presents a clear visual representation of the aircraft's heading relative to these navigation aids, allowing pilots to easily determine their orientation with respect to a selected station.

In functional terms, the RMI usually features a magnetic compass rose, and the aircraft's heading is indicated by a rotating card that aligns with the magnetic bearing. The bearing to the selected station is shown with a needle that points toward the station, while an additional needle may indicate the bearing from the station. This feature is crucial for navigational accuracy, allowing pilots to follow airways or make precise approaches to airports equipped with RNAV (Area Navigation) capabilities.

The other options do not accurately represent the primary function of an RMI. While altitude and airspeed are critical flight parameters, they are not displayed by an RMI. Similarly, while location and distance may be derived from a variety of navigation systems, they are not the specific data an RMI provides. Lastly, flight path and direction encompass broader concepts that involve various inputs from multiple navig
