 Proposed risk mitigation measures included curtailing flight movements during the afternoon swarm, setting the glide slope approach to Runway 06 to 3.2 or 3.5 degrees rather than the standard 3 degrees (to stay above the birds), and the installation of a radar system that would monitor bird movements and be integrated into the operational plan of the airport.In response to the study, ACSA contracted De-Tect Inc. to install a radar system that would monitor all bird activity around KSIA, notifying air traffic controllers of any dangers to aircraft.The radar system arrived in January 2009 and started collecting data to be used when the airport became operational.
