AMC12 ATS.TR.210(a)(3) Operation of air traffic control service
ED Decision 2020/008/R
INFORMATION TO AIRCRAFT BY AERODROME CONTROL TOWERS — AERODROME AND METEOROLOGICAL INFORMATION
(a) Prior to taxiing for take-off, the aerodrome control tower should advise aircraft of the following elements of information, in the order listed, with the exception of such elements which are known to have been already received by the aircraft:
(1) the runway to be used;
(2) the surface wind direction and speed, including significant variations therein;
(3) the QNH altimeter setting and, either on a regular basis in accordance with local arrangements or if so requested by the aircraft, the QFE altimeter setting;
(4) the air temperature for the runway to be used, in the case of turbine-engined aircraft;
(5) the visibility representative of the direction of take-off and initial climb, if less than 10 km, or, when applicable, the RVR value(s) for the runway to be used; and
(6) the correct time.
(b) Prior to take-off, the aerodrome control tower should advise aircraft of:
(1) any significant changes in the surface wind direction and speed, the air temperature, and the visibility or RVR value(s) given in accordance with point (a); and
(2) significant meteorological conditions in the take-off and climb-out area, except when it is known that the information has already been received by the aircraft.
(c) Prior to entering the traffic circuit or commencing its approach to land, the relevant air traffic controller unit should provide aircraft with the following elements of information, in the order listed, with the exception of such elements which are known to have been already received by the aircraft:
(1) the runway to be used;
(2) the surface wind direction and speed, including significant variations therein;
(3) the QNH altimeter setting and, either on a regular basis in accordance with local arrangements or if so requested by the aircraft, the QFE altimeter setting; and
(4) changes in observed RVR value(s), in accordance with the reported scale in use, or changes in the visibility representative of the direction of approach and landing.
Aerodrome control towers must provide aircraft with essential aerodrome and weather information before taxiing, takeoff, and landing approach. This includes runway in use, wind, QNH/QFE, temperature (turbine aircraft), visibility/RVR, and time. Updates on significant changes and meteorological conditions are also required for safe air traffic control.
