ED Decision 2020/008/R

SURFACE WIND — SITING

(a)     Reported surface wind should be representative of a wind at a height of 30 ± 3 ft (10 ± 1 m) above the ground.

(b)     Representative surface wind observations should be obtained by the use of sensors appropriately sited.

(c)      Sensors for surface wind observations for local routine report and local special report should be sited to give the best practicable indication of conditions along the runway and touchdown zones.

(d)     At aerodromes where topography or prevalent weather conditions cause significant differences in surface wind at various sections of the runway, additional sensors should be provided.
