TACAN-only aircraft

TACAN-only aircraft

An aircraft, normally military, possessing TACAN (tactical air navigation) with DME (distance-measuring equipment) but no VOR (very high frequency omnidirectional radio-range) navigational system capability. Clearances must specify TACAN or VORTAC (very high frequency omnidirectional radio-range tactical air navigation) fixes and approaches, although many TACAN and VORTAC stations are co-located.
