Azimuth-Elevation Deviation Indicator

An Azimuth-Elevation Deviation Indicator (AEDI) is a type of instrument used in aviation to display the deviation of an aircraft's position from a desired azimuth and elevation. It is commonly used in aircraft navigation systems, such as radar or satellite-based systems.

The AEDI provides pilots with real-time information about the aircraft's position relative to a desired azimuth (horizontal angle) and elevation (vertical angle). It typically consists of a display unit that shows the deviation in degrees or other units, and may also include additional indicators or lights to provide visual cues.

The AEDI is an important tool for pilots to maintain accurate navigation and ensure the aircraft is on the correct flight path. By monitoring the deviation indicated by the AEDI, pilots can make adjustments to their heading and altitude to stay on course.

Overall, the Azimuth-Elevation Deviation Indicator is a valuable instrument that helps pilots maintain precise navigation and ensure safe and efficient flight operations.
