Description / Abstract: This document defines and allocates the set of minimum requirements for the end-to-end operational, safety, performance, and interoperability aspects for implementations of the TSAA application. The TSAA application augments flight crew traffic situation awareness by providing alerts of traffic that is detected in conflict with ownship in support of the see-and-avoid responsibility. The TSAA application supports the out-the-window visual acquisition of traffic through voice annunciations of alerted traffic, visual cues, and additional symbology to supplement the plan-view depiction of traffic on a Traffic Display, when equipped. Visual cues of Nearby Airborne Traffic are provided by the TSAA application when equipped with a Traffic Display.
