Deployment Scenario Title

Enhanced safety nets

Deployment Scenario Description Enhanced safety nets: this deployment scenario includes improvements associated with short-term conflict alert (STCA), a ground-based system designed and deployed as a safety net to prevent collisions in both en-route and TMA environments. Improving on existing STCA technology, the enhanced algorithms for STCA support controllers in identifying possible conflicts between aircraft, ensuring earlier warnings and lower rates of false and nuisance alerts. The system also makes use of downlinked aircraft parameters, available through mode S enhanced surveillance.
