During its September meeting, the Program Management Committee (PMC) of RTCA conducted a comprehensive review and approval process, resulting in the endorsement of four new documents for publication and the approval of four Terms of Reference (ToR) changes. Chaired by Dr. Chris Hegarty from The MITRE Corporation, this 21-member committee plays a crucial role in ensuring aviation system interoperability, innovation, and adherence to FAA regulations. Notable discussions encompassed key topics, including:

Approved Documents:

  • DO-401 – Minimum Operational Performance Standards (MOPS) for Dual-Frequency Multi-Constellation Satellite-Based Augmentation System Airborne Equipment. This document supports validation for operations utilizing Dual Frequency Global Positioning System (GPS), Galileo, and Satellite-Based Augmentation System (SBAS) signals.
  • DO-404 – Minimum Aviation System Performance Standard (MASPS) on ATN-IPS End-To-End Interoperability and Certification, which provides guidelines for achieving global system interoperability in air-ground communication standards.

DO-401, DO-401 Supplement and DO-404 are available with detailed descriptions in the RTCA Store:  

  • DO-350B – Safety and Performance Requirements Standard for Baseline 2 ATS Data Communication (Baseline 2 SPR Standard) Vol I & II, outlining operational, safety, and performance requirements for data communication services supporting Air Traffic Services (ATS).
  • DO-351B – Interoperability Requirements Standard for Baseline 2 ATS Data Communication (Baseline 2 INTEROP Standard) Vol I & II, setting interoperability requirements for Air Traffic Service (ATR) applications supporting Baseline 2 Data Link Services.
