Purpose of this Document

This document describes a Traffic Computer with Traffic Alert and Collision Avoidance System (TCAS) functionality that provides the necessary interface definitions and protocols to accommodate the requirements of RTCA DO-185B: Minimum Operational Performance Standards (MOPS) for Traffic Alert and Collision Avoidance System II (TCAS II) (latest version applies).

Additionally, this document describes interfaces and protocols necessary to accommodate Cockpit Display of Traffic Information (CDTI) based on reception of Automatic Dependent Surveillance - Broadcast (ADS-B) data and Traffic Information Services - Broadcast (TIS-B) data. The equipment becomes TCAS with ADS-B IN applications added, as defined by RTCA DO-317B: Minimum Operational Performance Standards for (MOPS) for Aircraft Surveillance Applications (ASA) Systems (latest version applies).

This document addresses interfaces and protocols required for the TCAS II Hybrid Surveillance function as described in RTCA DO-300A: Minimum Operational Performance Standards (MOPS) for Traffic Alert and Collision Avoidance System II (TCAS II) Hybrid Surveillance (latest version applies).
