TRAC is a route/airspace design, fast-time traffic simulation, andanalysis tool for studying NextGen trajectory-based operations. TRAC has been updated to enable users to readily specify trajectory-modification options, referred to as degrees of freedom, for controlling aircraft flying Area Navigation/Required Navigation Performance routes. This paper describes the graphical specification scheme and presents example use cases drawn from research on super-density terminal-area operations. The examples illustrate how the capability has been integrated with other TRAC simulation and analysis capabilities, and highlight some implications of employing certain trajectory-modification options in candidate operational concepts. |
