What color are TACAN checkpoint markings?

The main idea is how TACAN checkpoint markings are standardized to be identifiable without interfering with navigation equipment. TACAN checkpoints use yellow markings that are nonreflective. This color choice helps these marks stand out from other pavement markings while signaling they’re related to TACAN rather than runways or taxiways. Making them nonretroreflective avoids glare or confusing reflections from aircraft lights or other sources at night, which could complicate visual cues around the TACAN facility. Using retroreflective or white markings would either introduce glare or conflict with the conventional colors used for runways (white) and general taxiways (yellow), so nonreflective yellow best fits the intended purpose.
