ED-236A "Minimum Operational Performance Standards (MOPS) for Flight-deck Interval Management (FIM)"

We are pleased to announce the publication of ED-236A “Minimum Operational Performance Standards (MOPS) for Flight-deck Interval Management (FIM).”
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, EUROCAE ED-194A / RTCA DO-317B. 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, ED-194A / DO-317B, unless explicitly stated otherwise. Revision A of ED-236 contains:

• Removal of the Progress Indicator;

• New functional requirements for Non-Coincident Routes;

• New functional requirements to support IM sequential clearances;

• “IM Speed Conformance” requirements changed to “IM Speed Compliance”;

• Improved trajectory recalculation requirements;

• Addressed lessons learned from flight test/demo activities;

• New functional requirements to support operations enabled by data communications – specifically Controller/Pilot Data Link Communication (CPDLC) and ATS Winds;

• New functional requirements for downlinking FIM Application Information via transponder register;

• New functional requirements to support new information exchanges as defined in ED-102B / DO-260C (Traffic Reported Airspeed, Traffic Sensed Wind, Traffic Static Air Temperature).

Available on the EUROCAE website.
