CS ADR-DSN.L.525 Runway designation marking

(a)Applicability: A runway designation marking should be provided at the thresholds of a runway.

(b)Location and positioning: A runway designation marking should be located at a threshold as shown in Figure L-1 as appropriate.

(c)Characteristics:

(1)A runway designation marking should consist of a two-digit number and on parallel runways should be supplemented with a letter.

(i)On a single runway, dual parallel runways and triple parallel runways, the two-digit number should be the whole number nearest the one-tenth of the magnetic North when viewed from the direction of approach.

(ii)On four or more parallel runways, one set of adjacent runways should be numbered to the nearest one-tenth magnetic azimuth and the other set of adjacent runways numbered to the next nearest one-tenth of the magnetic azimuth.

(iii)When a runway designation marking consists of a single digit number, it should be preceded by a zero.

(2)In the case of parallel runways, each runway designation number should be supplemented by a letter as follows, in the order shown from left to right when viewed from the direction of approach:

(i)for two parallel runways: ‘L’ ‘R’;

(ii)for three parallel runways: ‘L’ ‘C’ ‘R’;

(iii)for four parallel runways: ‘L’ ‘R’ ‘L’ ‘R’;

(iv)for five parallel runways: ‘L’ ‘C’ ‘R’ ‘L’ ‘R’ or ‘L’ ‘R’ ‘L’ ‘C’ ‘R’; and

(v)for six parallel runways: ‘L’ ‘C’ ‘R’ ‘L’ ‘C’ ‘R’.

(3)The numbers and letters should be in the form and proportion shown in Figure L-2. The dimensions should be not less than those shown in Figure L-2. Where the numbers are incorporated in the threshold marking, larger dimensions should be used in order to fill adequately the gap between the stripes of the threshold marking.
