OSYRIS is an integrated suite of arrival, departure and flow-management software that allows resources to be used flexibly, reduces workload and manages queues safely and efficiently in today's crowded air traffic environment. OSYRIS can help increase the capacities of limited airside and airport resources like runways and airspace. In addition, OSYRIS makes aviation more economical and environmentally responsible because it helps reduce fuel consumption and greenhouse gas emissions. The OSYRIS Queue Management Tools are designed to adapt to increasing expectations for more efficient traffic flows and airport operations. The concept of this suite is to generate planning advisories, enabling specific tasks to be automated and improving air traffic control and airport operations.
