VORTACs, which combine VOR (VHF Omnidirectional Range) and TACAN (Tactical Air Navigation), are critical navigation aids utilized by aircraft for both civilian and military aviation operations. Each VORTAC is assigned a unique identifier, usually comprised of three letters.

In the case of Chisum VORTAC, 'CME' is derived from the location and the established naming conventions used within the aviation community.
