Interpretation

Migrating bird flocks are expected around the aerodrome: within 3 km of the aerodrome reference point at true heights of 0–300 m, and between 3 km and 13 km at true heights of 800–3,000 m. Peak movements are 2340–0130 the next day from north to south, 1050–1230 from south to north, and 1100–1500 from east to west or west to east. The aerodrome authority will use dispersal methods; exercise caution during takeoff and landing.
