ED-271A – Minimum Aviation System Performance Standards For Detect And Avoid Traffic For Remotely Piloted Aircraft Systems In Airspace Classes A-G Under IFR

This document functions as a MASPS for the Detect & Avoid [Traffic] system (DAA) for Remotely Piloted Aircraft Systems (RPAS) operating in certified category in class A to G airspaces under Instrument Flight Rules (IFR). This standard specifies a proportionate risk based standard for Detect & Avoid against conflicting traffic which will support a performance based regulation for non-segregated RPAS operation.
Revision A supersedes ED-271 ‘MASPS for Detect And Avoid [Traffic] for Remotely Piloted Aircraft Systems in Airspace Classes A-C under IFR’ (May 2022) which has been updated to expand from operations in airspace classes A-C to cover all airspace classes A-G.
Main changes are:
– Updated alerting and guidance requirements for RWC,
– Assumed RP behaviour based on RWC alerting and guidance,
– Performance requirements for RWC,
– Harmonization with established ICAO Risk Ratios and Loss of Well Clear ratios.
