What navigation information can a pilot obtain from a TACAN?

A TACAN, or Tactical Air Navigation system, provides pilots with distance measuring equipment (DME) capabilities. It allows pilots to determine their distance from the TACAN station by calculating the time it takes for a signal to travel from the station to the aircraft and back. This distance information is critical for navigation, particularly in military operations, and is utilized in both tactical flight operations and standard flight procedures.

The other options do not pertain to the capabilities of a TACAN. Wind direction is typically obtained from meteorological data or onboard instruments rather than from a TACAN signal. Altitude information is measured using altimeters and related systems, not provided by TACAN. Flight plan routing details are managed through air traffic control and navigation systems, but not specifically through the TACAN, which focuses primarily on providing distance and bearing information. This makes the answer regarding DME the most relevant and accurate in the context of TACAN capabilities.
