A fast-time simulation model of air traffic in the National Airspace System (NAS), developed by the Center for Advanced Aviation System Development (CAASD) of The MITRE Corporation, has been used over the past several years for capacity and delay analyses. Prior to the effort documented in this paper, this model did not explicitly account for the communications events that transpire, and the related communications messages that would ensue, as the simulated aircraft are moving through the NAS. The model did account for overall controller workload, which incorporates communications workload, in an abstract sense. In order to properly engineer current and future air/ground (A/G) communications systems, it is necessary to explicitly quantify the communications traffic that those systems support. This paper describes the capability added to the simulation model during fiscal year 2005 (FY2005) to identify communications message triggering events, and to generate the appropriate voice or data communications messages. This work was facilitated through the MITRE Sponsored Research (MSR) Program of the MITRE Technology Program.
