Information to TACAN

The TACAN provides permanent data about direction and distance to a selected TACAN-transmitter up to a distance of 400 miles. The bearing, course, distance and relative position to pre-selected course are shown on the HSI according to the selection made with the INT MODE selector button on the INSTR Panel. TACAN uses two different bands X is used by ground- stations, while Y can be used by aircraft (tankers, for example), as well as ground-stations. TACAN is the analog device to the civilian VOR.
