ADR.OPS.B.071 Closed runways and taxiways, or parts thereof

CLOSED MARKING

(a)The closed marking should be in accordance with CS ADR-DSN.R.855.

(b)On a runway, a closed marking should be placed at each end of the runway, or part thereof, declared closed and additional markings should be so placed that the maximum interval between markings does not exceed 300 m.

(c)On a taxiway, a closed marking should be placed at least at each end of the taxiway, or part thereof closed.

CLOSED RUNWAY AND TAXIWAY MARKINGS — AVOIDING THE LACK OF CONTRAST

(a)In certain circumstances, e.g. due to the colour of the material used during construction works, there may be insufficient contrast between the colour of the surface of the runway or taxiway and the colour of the respective closed runway or taxiway marking, even though the latter conforms to the applicable specifications. This may result in the closed runway or taxiway markings not fulfilling their purpose. To avoid the lack of contrast, the closed runway or taxiway markings need to be included in an appropriate border, whose colour is black.

(b)At aerodromes where operations take place at night, the closed runway or taxiway markings would be made with reflective materials designed to enhance their visibility. Guidance on reflective materials is given in Part 4 ‘Visual Aids’ of ICAO Doc 9157 ‘Aerodrome Design Manual’.

UNSERVICEABILITY LIGHTS AT ENTRANCES OF CLOSED RUNWAYS AND TAXIWAYS OR PARTS THEREOF Unserviceability lights should be in accordance with CS ADR-DSN.R.870 and should be placed across the entrance to the closed area at intervals not exceeding 3 m.
