ATS.OR.515 Meteorological information for aerodrome control towers and AFIS units

(a)An air traffic services provider shall ensure that aerodrome control towers and, unless otherwise prescribed by the competent authority, AFIS units are supplied with meteorological information for the aerodrome with which they are concerned as stipulated in point MET.OR.242(a) of Annex V.

(b)An air traffic services provider shall ensure that aerodrome control towers and AFIS units are provided with current pressure data for setting altimeters for the aerodrome concerned.

(c)An air traffic services provider shall ensure that aerodrome control towers and AFIS units are equipped with surface wind display or displays. The display or displays shall be related to the same location or locations of observation and be fed from the same sensor or sensors as the corresponding display or displays in the aeronautical meteorological station, where such a station exists. Where multiple sensors are used, the displays to which they are related shall be clearly marked to identify the runway and section of the runway monitored by each sensor.

(d)An air traffic services provider shall ensure that aerodrome control towers and AFIS units at aerodromes where runway visual range values are measured by instrumental means, are equipped with display or displays permitting read-out of the current runway visual range values. The display or displays shall be related to the same location or locations of observation and be fed from the same sensor or sensors as the corresponding display or displays in the aeronautical meteorological station, where such a station exists.

(e)An air traffic services provider shall ensure that aerodrome control towers and AFIS units at aerodromes where the height of cloud base is assessed by instrumental means, are equipped with display or displays permitting read-out of the current values of the height of cloud base. The displays shall be related to the same location or locations of observations and be fed from the same sensor or sensors as the corresponding display or displays in the aerodrome control tower and AFIS units and in the aeronautical meteorological station, where such a station exists.

(f)An air traffic services provider shall ensure that aerodrome control tower and AFIS units are supplied with available information on wind shear which could adversely affect aircraft on the approach or take-off paths or during circling approach, and aircraft on the runway during the landing roll or take-off run.

(g)An air traffic services provider shall ensure that aerodrome control towers and AFIS units and/or other appropriate units are supplied with aerodrome warnings, in accordance with point MET.OR.215(b) of Annex V
