The number of stripes or bars painted also indicates the. These markings painted ahead of runway threshold. The runway threshold markings consist of white longitudinal stripes of uniform dimension arranged evenly about the runway center-line. When the runway designation is placed within a threshold marking, there will be at least three stripes on either side of the runway center line. A threshold marking identifies the beginning of the runway that is available and suitable for landing. This ensures the safety and efficiency of air strip operations. Runway threshold markings are stripes of uniform width and length disposed symmetrically about a runway’s centerline. The team at Top End Line Markers will work to your air strip project plans and ensure that all lines are marked correctly.

They also feature runway designators which include a letter and number that determine approach direction. Precision runway markings have the same threshold markings and runway number as non-precision runways however, they also feature touchdown zone markers that identify the touchdown zone for landing operations. Threshold markings identify the beginning of the runway that is available and suitable for landing. They will also have threshold markings before the runway number, which are broad white stripes located on either side of the centreline. Non-precision runway markings are similar to visual runways as they feature a number and dashed runway centreline. For example, the visual runways are marked with the runway number and a dashed runway centreline. Each of these classifications has an associated level of marking. There are 3 classifications for runway markings including visual runways, non-precision runways and precision runways. Any pre-runway markings including holding positions and taxiways must be made in yellow. Runway markings are always painted in white regardless of whether they are on concrete, asphalt or sealed runway surfaces.
