PANS-ATM, CHAPTER 7, PARAGRAPH 7.2.6
Editorial Note.— New text is highlighted and
deleted text is struck out.
...
7.2.6 Noise abatement shall not be a determining factor in runway nomination under the following
circumstances:
...
e)
when the crosswind component, including gusts, exceeds 28 km/h (15 kt), or the tailwind
component, including gusts, exceeds 9 km/h (5 kt), unless the following requirements are met, in which
case noise abatement can be the determining factor in runway nomination to a maximum crosswind
component, including gusts, of 37 km/h (20 kt), or a maximum tailwind component of 13 km/h (7 kt)
including gusts:
i)
The wind reporting system for the touchdown and take-off area, incorporating implementation of
additional wind measuring sensors and data processing meets the following accuracy of
measurement criteria;
1) Mean Surface Wind Direction: ± 10º
2) Mean Surface Wine Speed: 0.5m/s (1kt) up to 5 m/s (10 kt) and ± 10% above 5
m/s (10 kt)
3) Variations from the Mean Surface Wind: ± 1 m/2 (2 kt), in terms of longitudinal
and lateral components;
ii) A procedure is in place to monitor and compare flight data with data derived from the wind
reporting system in e) i) as part of a continuous safety risk assessment process to ensure that
aeroplanes do not exceed demonstrated crosswind values or certified tailwind limits;
iii) Precision approach guidance is available for the runway in use;
iv) Arriving and departing aeroplanes are advised as part of the landing or take-off clearance, when
variations from the mean wind speed (gusts) exceed 9 km/h (5 kt);
v) The current surface wind is reported by ATC to aeroplanes on final approach after entering the
Final Approach Segment or equivalent position;

vi) Reported braking action remains “good”; and
vii) At aerodromes with multiple runways, the wind information for each separate runway in use is
included in the information provided by the automatic terminal information service (ATIS).
