Which navigation system combines direction determining and distance measuring equipment at the same ground station?

• A. VOR
• B. NDB
• C. VORTAC
• D. ILS

Answer: (C)

The navigation system that integrates direction determining and distance measuring equipment at the same ground station is the VORTAC. This system combines the capabilities of a VOR (VHF Omnidirectional Range) and a TACAN (Tactical Air Navigation) station. The VOR provides pilots with directional guidance, helping them navigate by indicating their bearing relative to the station. On the other hand, TACAN offers distance measuring capabilities, enabling aircraft to determine how far they are from the station. By combining these two functionalities, the VORTAC allows for more precise navigation, which is essential for both civilian and military aviation operations. In contrast, a VOR only provides directional information without distance measurement, an NDB (Non-Directional Beacon) provides simpler directional guidance using low-frequency radio signals, and an ILS (Instrument Landing System) primarily assists in landing approaches rather than providing continual directional and distance data during en route navigation. Thus, the VORTAC is the unique system that combines both direction determining and distance measuring capabilities at a single ground station.
