Deployment Scenario Title

Enhanced airborne collision avoidance for commercial air transport normal operations (ACAS Xa)

Deployment Scenario Description Enhanced airborne collision avoidance for commercial air transport normal operations (ACAS Xa): this is an airborne collision avoidance system that takes advantage of optimised resolution advisories and additional surveillance data but will not change the cockpit interface (i.e. it uses the same alerts and presentation as the current traffic collision avoidance system).
