What information does the EHSI display when tuned to a navigation facility with DME capability?

When the Electronic Horizontal Situation Indicator (EHSI) is tuned to a navigation facility with Distance Measuring Equipment (DME) capability, it automatically displays DME information. This information includes the distance from the aircraft to the ground station, providing pilots with critical situational awareness regarding their proximity to the navigation aid.

The DME system works in conjunction with VOR and ILS, and when the EHSI is set to a relevant frequency, the DME data becomes available on the display without the need for manual input or selection by the pilot. This automation enhances flight safety and efficiency by allowing pilots to easily access pertinent navigation data that is essential for maintaining safe distances from waypoints and navigating along specified flight routes.

The other options do not pertain to the direct capability of the EHSI with respect to DME. For example, flight plans and route navigation details are typically handled through other systems or inputs and aren’t displayed automatically solely because DME is tuned. Altitude information is also not a function of the DME capability but rather comes from other instruments on the aircraft.
