Interpretation

Bird flocks are migrating around the aerodrome and adjacent airspace, with higher activity during 1200-1800 at 300 m to 4,500 m and sporadic activity 2230-1100 the next day at 0 m to 50 m; some birds are active at 100 m to 150 m prior to landing on RWY 20L/02R/03. Significant migratory bird concentration is expected May 10-12, increasing bird strike risk, and the aerodrome authority is using dispersal methods to reduce bird activity.

1. SEASONAL MIGRATORY BIRD THROUGH AD AND ADJACENT 
AIRSPACE,MIGRATION ROUTE: FROM SOUTH TO NORTH.MIGRATION TIME ALL 
DAY,BIRD ACTIVITY IS RELATIVELY HIGH DURING 1200-1800 AT ALT OF 
300M-4,500M,BIRD STRIKE ARE MORE LIKELY TO OCCUR DURING THE 
FLIGHT PHASE AT DISTANCE OF 10KM-35KM RWY THR AND ALT OF 
900M-1,800M.
2. MAY 10-12, SIGNIFICANT CONCENTRATION OF MIGRATORY BIRD 
MOVEMENT IS EXPECTED,INCREASING THE RISK OF BIRD STRIKE WHICH MAY 
CAUSE ACFT DAMAGE.
3. SPORADIC BIRD ACTIVITY TIME: 2230-1100(NEXT DAY),ALT: 0M-50M.
SOME BIRDS ARE ACTIVE AT ALT OF 100M-150M PRIOR TO LANDING ON 
RWY20L/02R/03.
AERODROME AUTHORITY RESORTS TO DISPERSAL METHODS TO REDUCE BIRD
