On Sunday, flight VJC720/A321 VVDN-VVCI detected a drone at 1,700 feet, or 518.16 meters, to the right of the aircraft. This intrusion directly affected 19 flights, with nine planes waiting on the ground and 10 circling in the air.
Airport authorities said that once the drones were detected, air traffic controllers immediately coordinated with relevant agencies, instructed aircraft to hold positions, and applied conditional take-off and landing schedules.
After the incidents were resolved, operations returned to normal.
