Runway Threshold Markings Explained: Standard vs. Displaced Threshold #3405393 (License: Personal Use)

The image displays two parallel runway diagrams oriented east-west (runway 27/60). The top diagram shows a standard runway threshold with full-length dashed centerline and touchdown zone markings (rectangular bars) extending from the threshold. The bottom diagram illustrates a displaced threshold: the threshold bar is moved downfield, and the area before it lacks touchdown zone markings but retains the centerline dashes, indicating it’s not usable for landing.

Used in aviation training materials, FAA/AIP documentation, pilot handbooks, and air traffic control guides to teach runway marking conventions. Matches user intent to learn how to interpret runway surface markings during pre-flight planning or instrument training.
