What three individual navigation services are provided by a VORTAC facility?

A VORTAC facility provides three individual navigation services, namely VHF VOR azimuth, UHF TACAN azimuth, and UHF TACAN distance information.

The VHF VOR (Very High Frequency VHF Omnidirectional Range) offers azimuth information, helping pilots determine their direction relative to the VOR station. This is essential for en route navigation as it allows aircraft to maintain their intended flight path.

The TACAN (Tactical Air Navigation) component of the VORTAC provides both azimuth and distance information. The UHF TACAN azimuth gives an additional means of determining the aircraft's bearing relative to the TACAN station, which is particularly useful for military operations and in areas where VOR coverage may be limited. The UHF TACAN distance information is provided through a distance measuring equipment (DME) component, allowing pilots to gauge their distance from the TACAN station, which aids in RNAV (Area Navigation) and situational awareness.

Together, these services from a VORTAC facility create a comprehensive navigation aid that supports both civilian and military aircraft by providing critical data for accurate navigation during en route and approach phases of flight.
