Interpretation

Bird flocks and migration activity occur airfield-wide all day from the surface up to 6,000 m, with peak movement areas southeast of the southern flight area, near northern flight area woodlands, water sources along the airfield perimeter, airfield villages, runway edges, and across soil-surface runway/taxiway areas. High‑risk areas include the Qinling Mountains (crossing alert) and Shuangzhao Lake Park (10.6 km on QDR 246° from the aerodrome reference point). There is an added risk of high‑altitude strikes at night. Exercise caution during takeoff and landing.
