This document was prepared jointly by RTCA Special Committee 186 (SC-186) and EUROCAE Working Group 51 (WG51). This document contains the Minimum Operational Performance Standards (MOPS) for the Flight-deck-based Interval Management (FIM) application building upon the MOPS for the Aircraft Surveillance Applications (ASA) System, RTCA DO-317B/EUROCAE ED-194A. Because of the length and complexity of the additional requirements for the FIM application, they are included in this separate document. The FIM application requirements in this document are assumed to be integrated in an ASA System that is compliant with all requirements related to the Basic Airborne Situational Awareness (AIRB) application, which is defined in the ASA MOPS, DO-317B / ED-194A, unless explicitly stated otherwise.
