STANDARDS OVERSIGHT COMMITTEE ACTS ON EMERGING TECHNOLOGIES IN ADS-B, UAS AND SATCOM

March 30, 2020

Washington, DC, March 26, 2020 – RTCA’s Program Management Committee (PMC) held its spring meeting approving seven guidance documents, reviewing workplans for the Special Committees (SC), and incorporating changes to the various committee Terms of Reference (TOR) that reflect leadership and work plan changes.

 

Chaired by Dr. Chris Hegarty of The MITRE Corporation, the 19-member PMC is the RTCA oversight body charged with producing timely and robust standards and guidance documents to ensure interoperability of aviation systems and equipment. The standards encourage innovation and serve as the basis for meeting Federal Aviation Administration (FAA) regulations. An important responsibility of the PMC is ensuring the operational application of the technical standards.

 

The Members of the PMC approved seven revised standards:

 

  • DO-328B – Safety, Performance and Interoperability Requirements Documents for Airborne Space – Flight Deck Interval Management (ASPA-FIM) prepared by SC-186, Automatic Dependent Surveillance Broadcast (ADS-B)

 

This document provides the minimum operational, Safety and Performance Requirements (SPR) and Interoperability Requirements (INTEROP) to implement Airborne Spacing (ASPA) - Flight Deck Interval Management (FIM) in support of an identified set of IM Operations. ASPA-FIM is defined as the flight deck component of the Interval Management (IM) System. The IM System includes the ground domain’s tools to generate IM Clearance information for the controller to provide to IM equipped aircraft. Then, based upon the IM Clearance provided by the controller and surveillance information received on the aircraft against which the relative spacing is desired (referred to as the Target Aircraft), ASPA-FIM generates guidance for the flight crew to successfully and safely comply with the IM Clearance.

 

  • DO-361A – MOPS for Flight-Deck Interval Management (FIM) prepared by SC-186, Automatic Dependent Surveillance Broadcast (ADS-B)

 

This document contains the Minimum Operational Performance Standards (MOPS) for Flight-deck Interval Management (FIM). These requirements build on those described in the MOPS for the Aircraft Surveillance Applications (ASA) System, RTCA DO-317C / EUROCAE ED-194B, but are documented separately due to their length and complexity. The 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 (defined in DO-317C / ED-194B), unless explicitly stated otherwise. 

 

  • DO-210D Change 5 – MOPS for Geosynchronous Orbit Aeronautical Mobile Satellite Services (AMISS) Avionics) prepared by SC-222, Aeronautical Mobile Satellite (Route) Services AMS(R)S

 

This change note introduces requirements for blocking immunity from International Mobile Telecommunication (IMT) base stations in the bands 1492 to1517 MHz and 1526 to1536 MHz.

 

The system level requirement for blocking immunity has been partitioned between the DLNA and the rest of the transceiver so that any installation of an AES which provides only Classic Aero service (Aero H, Aero H+ or Aero I) may be upgraded by replacing the existing DLNA with a Type H or Type J DLNA.

Similarly, any installation of an AES which provides both Classic Aero service (Aero H, Aero H+ or Aero I) and non-safety Swift Broadband (SBB) or Swift-64 services may be upgraded by replacing the existing DLNA with a Type J DLNA.

 

Substitution of a DLNA into an installed AES should not require re-testing of the complete AES as long as the superior performance of the replacement DLNA is demonstrated by the test requirements within this change note.

 

  • DO-262E – MOPS for Avionics Supporting Next Generation Satellite Systems (NGSS) prepared by SC-222, Aeronautical Mobile Satellite (Route) Services AMS(R)S

 

This document contains MOPS for avionics that provide Aeronautical Mobile Satellite (R) Services (AMS(R)S) by means of satellite communications technologies scheduled to become operational in context of the global and regional ATM and CNS modernization (e.g. ICAO/Global Air Navigation Plan, Europe/SESAR, US/NextGen).  Each of these technologies is individually and collectively referred to as a “Next Generation Satellite System” (NGSS), and the NGSS nomenclature will be used throughout this document.  This document does not apply to avionics that provide AMS(R)S in accordance with the Standards and Recommended Practices defined in ICAO Annex 10, Part I, Volume III, Chapter 4 (Chapter 4 SARPS). Such equipment is specified in the current version of RTCA DO-210D.

 

  • DO-343C - MASPS for AMS(R)S Data and Voice Communications Supporting Required Communications Performance (RCP) and Required Surveillance Performance (RSP) prepared by SC-222, Aeronautical Mobile Satellite (Route) Services AMS(R)S

 

This document contains Minimum Aviation System Performance Standards (MASPS) for AMS(R)S that provide safety communications to aircraft in airspace where 1) procedural separation is applied or 2) ATS surveillance services are provided.  The performance defined in this document is intended to provide (1) data communication services that comply to the RCP130/A1, RCP240/A1, RCP400/A1 or RCP400/A2 standards of Required Communications Performance (RCP) for two-way, bidirectional, Controller Pilot Data Link Communications (CPDLC) and to the RSP160/A1, RSP180/A1 or RSP400/A1 standards of Required Surveillance Performance (RSP) for one-way aircraft-to-Air Navigation Service Provider surveillance-related information, and (2) voice communication services that comply to the RCP400/V standard for two-way, bidirectional voice communications between pilots and controllers and to the RSP400/V standards for one-way voice communications between pilots and controllers.

 

  • DO-365A – MOPS for Detect and Avoid (DAA) Systems) prepared by SC-228, Minimum Performance Standards for Unmanned Aircraft Systems

 

This document contains MOPS for Detect and Avoid (DAA) systems used in aircraft transiting and performing extended operations in Class D, E, and G airspace along with transiting Class B and C airspace. It includes equipment to enable UAS operations near Terminal Areas during approach and departure in Class C, D, E, and G airspace, and off‑airport locations, but not operating in the visual traffic pattern or on the surface. It does not apply to small Unmanned Aircraft Systems (UAS) (under 55 pounds (lbs)) operating in low‑level environments (below 400') or other segmented areas.

 

  • DO-381 – MOPS for Ground-based Surveillance System (GBSS) for Traffic Surveillance prepared by SC-228, Minimum Performance Standards for Unmanned Aircraft Systems

This document contains MOPS for Ground Based Surveillance Systems (GBSS) used for air traffic surveillance in support of DAA operations for unmanned aircraft. The primary applications will be used in terminal, transit, or extended operational areas in the National Airspace System (NAS) as defined in RTCA Document 365A (DO‑365A), Minimum Operational Performance Standards for Detect and Avoid Systems. These standards specify the GBSS characteristics that should be useful for designers, manufacturers, installers and users of the equipment. Note that in this context, surveillance “systems” includes one or more networked non-cooperative sensors (e.g., radar and lidar), Electro-Optical/Infrared (EO/IR), etc.) needed to meet these MOPS. Also note that these MOPS do not address cooperative ground-based sensors (e.g., radar beacon, Mode Select (Mode S), Automatic Dependent Surveillance-Broadcast (ADS‑B), multilateration, etc.).

 

One new committee was approved – Topics on Software Advancement (SC-240).

 

Six special committees received approval for changes to their work plans.  These included SC-135, Environmental Testing, SC-159, Navigation Equipment Using the Global Navigation Satellite System (GNSS), SC-206, Aeronautical Information and Meteorological Data Link Services, SC-227, Standards of Navigation Performance, SC-228, Minimum Performance Standards for Unmanned Aircraft Systems, and SC-235, Non-Rechargeable Lithium Batteries.

 

Additionally, an Ad Hoc was formed to investigate and make possible recommendations concerning the Federal Communications Commission action on establishing the 5G spectrum band in the adjacent band of Radio Altimeter.
