What is the maximum operational range of a TACAN system?

The maximum operational range of a TACAN (Tactical Air Navigation) system is indeed up to 200 nautical miles (NM). TACAN provides accurate distance and bearing information to aircraft relative to a ground station. This system is commonly utilized in both military and civilian aviation for navigation.

The 200 NM range stands out because it allows for effective navigation over significant distances without needing other aids, making it a valuable tool in both training and operational scenarios. The system relies on line-of-sight radio signals, which ensure the accuracy of the information transmitted, but factors like terrain and the altitude of the aircraft may influence actual performance in practice.

In contrast, ranges such as 50 NM, 100 NM, or 300 NM do not reflect the established limits of TACAN operation. TACAN's range has been set based on its design specifications and performance in real-world conditions, which do not extend to 300 NM, as that would be outside the standard capacity of this navigational aid.
