Abstract

A method and system providing a computer human interface for use by an air traffic controller supported by various GNSS compatible control and management commands. A data entry capability allows the controller to select various GNSS based commands such as arrival and departure clearances to effectively control and manage the flow of traffic using GNSS and its augmentations. GNSS is used as the primary air and surface position and navigation sensor. GNSS compatible travel paths are utilized in clearances, navigation and for conformance and traffic flow monitoring purposes. Two display views enable the controller to observe the traffic situation on one display view, while other display views are predominately utilized for the presentation of control and management system commands, warning alerts, messages and other functions. Controller to Pilot Data Link Capability (CPDLC) for clearances is utilized in conjunction with clearance acknowledgments being generated aboard the cleared aircraft. Automatic Dependent Surveillance using GNSS position reports as well as a subordinate radar surveillance and Mode S input may be utilized for graphic display presentations and other functions of the controller computer human interface. Incursion detection, collision detection, conformance monitoring, and lighting control are performed as a background automated processing function. In the event of an alert condition, warnings are presented to controller using text messages and using the multi-color situation display. Incursion conditions on runways activate airfield lighting systems to alert landing or departing aircraft of a compromised runway.
