What distinguishes a VORTAC from a standard VOR?

A VORTAC is a type of navigation aid that uniquely combines VHF Omni-directional Range (VOR) signals with Tactical Air Navigation (TACAN) signals. This fusion allows aircraft to receive both the traditional VOR navigational information, which helps pilots determine their position and maintain their course, and TACAN signals, which are primarily used by military aircraft for position-fixing and distance measuring.

The integration of these two systems enhances navigation capabilities, providing more precise location data and allowing for effective operation in both civilian and military contexts. This means that a VORTAC station supports both civilian aircraft navigation and tactical military operations, making it a versatile tool for air traffic management and maneuvering.

In essence, the distinguishing feature of a VORTAC is its ability to provide dual navigation functionalities through the combination of VOR and TACAN signals, which cannot be achieved by a standard VOR alone.
