What does the acronym VORTAC stand for?

The acronym VORTAC stands for "VHF Omni-Directional Radio Range with TACAN." This term describes a navigational aid that integrates both VOR (VHF Omni-Directional Range) and TACAN (Tactical Air Navigation) systems. VOR provides radio navigation service for aircraft, allowing them to determine their position relative to a broadcast station, while TACAN is primarily used by military aircraft, offering distance measuring capabilities in addition to directional information.

The combination of these two systems allows for enhanced navigation services, providing pilots with both azimuth and distance information, which is essential for precise navigation, especially in terminal areas. This makes VORTAC an invaluable resource for improving situational awareness and aiding in the safe and efficient operation of aircraft in the airspace.

The other options, while they may contain terms related to navigational aids or radio systems, do not accurately reflect the full meaning of VORTAC as it is understood in aviation terminology.
