The distance measurement component of TACAN operates with the same specifications as do civil [[DME]]'s. Therefore to reduce the number of required stations, TACAN stations are frequently co-located with [[VOR]] facilities. These co-located stations are known as [[VORTAC]]'s. This is a station composed of a [[VOR]] for civil bearing information and a TACAN for military bearing information and military/civil distance measuring information. The TACAN transponder performs the function of a [[DME]] without the need for a separate, collocated [[DME]]. Because the rotation of the antenna creates a large portion of the azimuth signal, if the antenna fails, the azimuth component is no longer available and the TACAN downgrades to a [[DME]] only mode. | The distance measurement component of TACAN operates with the same specifications as do civil [[DME]]'s.

TACAN can operate in either receive mode (R), or transmit/receive (TR) mode. | |||

To set TACAN, go to the <tt>Equipment > Radio Settings</tt> dialog. When using in-air refuel, first read [[Howto: Air-Air Refueling]]. | To set TACAN, go to the <tt>Equipment > Radio Settings</tt> dialog. When using in-air refuel, first read [[Howto: Air-Air Refueling]]. | ||
The F-14 and F-15 have a TACAN control panel that needs to be set correctly. Refer to their documentation pages for more information. | |||
