The normal markings for such runways include the centerline marking, designation marking, fixed-distance marking, touchdown zone marking, side stripes, holding position markings for a taxiway or runway intersection and ILS critical
areas, holding position markings at runways or runway intersections when runways are normally used for land, hold-short operations, or taxiing. See
