What are displaced threshold markings composed of?

Displaced threshold markings are composed of a 10-foot wide threshold bar and four white arrowheads to indicate the beginning of the runway usable for landing. The threshold bar serves as a visual cue for pilots, marking the point where the landing should ideally occur, while the arrowheads provide additional guidance on the path of approach. This configuration helps differentiate the usable runway area from the portion that may not be suitable for landing due to obstructions or other factors. The other options do not accurately describe displaced threshold markings: a continuous line along the edge of the runway typically indicates runway edges, a single rectangular bar across the runway represents an actual runway threshold, and diagonal lines marking safety areas are used for runway safety zones, not for displaced thresholds.
