Interpretation

Bird flock and migration activity is centered at the aerodrome reference point with an 8 km radius, from surface to about 2,000 m, with peak (move fastigium) between 1000 and 0100 next day; migration route is from north to south, most migration occurs at night increasing bird strike risk, and the aerodrome authority is using dispersal methods — exercise caution during landing and take-off.
