The number of pairs is related to the LDA available: Touchdown zone markings consist of pairs of rectangular markings placed symmetrically to both sides of the runway centreline. The white cross indicates that the surface is unfit for normal aircraft movement, and unsuitable as stop way.Ī touchdown zone is provided for all ILS equipped runways and runways where additional identification of the touchdown zone is required.The yellow chevrons indicate the surface is unfit for normal aircraft movement, but suitable as stop way.Temporarily displaced threshold marking (the threshold is displaced for a period shorter than six months).Permanent displaced threshold marking (a threshold which is temporarily displaced but for any duration of six months or more, is considered as permanently displaced for the appropriate marking).The white arrows in the prethreshold area indicate that the surface is fit for ground movement of aircraft only (taxiing), and not for landing.
Pre-threshold marking is provided where a runway has:Ī displaced threshold is used where not all the runway is available for landing. Runway threshold markings are depending on runway width: Runway centreline markings are 30 meters long and separated by 30 meters between each mark. 5 runways = 26L, 26C, 26R, 27L, 27R ¶ Runway centerline If there are more than 3 parallel runways, the runway designator number must change as per example: " C" (Centre) exists if there is a third parallel runway, the runway situated in the middle will be designated with the letter "C"." R" (Right) indicates the runway situated on the right." L" (Left) indicates the runway situated on the left as seen from the approach,.Where parallel runways are located at an aerodrome with the same magnetic heading, the runway designator will include a letter R, L or C: The runway designator consists of a two digit number indicating the magnetic runway heading, rounded to the nearest 10 degrees. Runway marking requirements differ per runway classification: The chevrons indicating such a prethreshold area are yellow markings. The only exception is if a pre-threshold area is not suitable for normal movement of aircraft, but only serving as a stop way from the opposite end of the runway. This chapter will show the runway marking signs. This article will present the main aerodrome markings and signalization on runways and taxiways.
