Standardized Distance Marking Board

Model Number: SDMB-FGI-1904

Runway Length Still Ahead During takeoff and landing procedures, signs are utilized to alert pilots of the remaining distance. The signs are placed at a lateral distance of 45 meters and a longitudinal interval of 1000 feet along one or both sides of the runway. On a black background, a white numeral appears in the lettering. The markers provide the remaining distance in thousands of feet. There may be 50 feet less left than the sign indicates. The sign location has a tolerance of 50 feet. Because they fall outside of this tolerance, some signs might not be included.

The first and last sign locations are increased by half the “additional distance” when the runway length is not an even multiple of 1000ft. As usual, runway distance markers have a black background with a white number; however, the number “2” has a red background. The numbers on the placards denote how many thousands of feet are yet on the landing runway.
