ED-14 and DO-160 have been in existence for a long time and were initially a set of simple procedures and limits used to guarantee a minimum quality level regarding robustness of airborne equipment. Since they were first introduced their purpose has evolved and many sections aim to provide environmental stress conditions as similar as possible to actual inflight conditions, in particular when systems providing safety related functions are concerned. This has resulted in more complex considerations and consequently a need to provide more guidance to the user of the documents that are now published in a ED-234.
WG-14 works in coordination with RTCA SC-135 Environmental Test.

WG-49 has been reactivated to perform maintenance on the Mode S Transponder MOPS ED-73E and ED-115. It will work joint with RTCA SC-209.
The Mode S Secondary Surveillance Radar transponder system is a key element of ATM surveillance. It supports different applications including Mode S Elementary surveillance, Mode S Enhanced Surveillance, ADS-B surveillance applications and anti-collision applications such as ACAS. The interoperability of the Mode S transponder with other systems used on board aircraft or on the ground is crucial to achieve a safe and efficient ATM Operation.
During the revision experience from the operational use of Mode S will be integrated and problems detected will be corrected. Furthermore support for new procedures such as Interval Management will be implemented which requires the exchange of information between aircraft. Access to real-time environmental data such as wind, temperature and turbulence will also be realised. Spectrum protection is an additional topic that may require adaptations to the transponder implementations. Finally, preparing the transponder for new functionalities required by ACAS Xu will be an additional task.
During this activity, WG-49 will work in close cooperation with WG-51 ADS-B, WG-75 Traffic Collision Avoidance Systems and WG-73 Unmanned Aircraft Systems. Furthermore, WG-49 cooperates with RTCA SC-209. To facilitate this complex cooperation, a Combined Surveillance Committee has been set up.

After the publications of ED-136, EDs-137 and ED-138 as from 2009 the first objective of the reactivation of the WG-67 is to update the current revised ED 137B to version C according to the EUROCAE update process. As some EDs 137 are referenced in ICAO Doc 9896, these EDs are more and more considered as interoperability documents not only at European level but also at worldwide level. “ED-137” “Interoperability Standard for VOIP ATM Components” is now a well-known worldwide brand for VoIP implementation. WG-67 has currently received many EDs Change Requests to adapt ED-137 to legacy systems and specific technical environments, as done for example with the current ED-137 Volume 3 standardizing the gateways managing the conversion to VoIP of the European legacy standards (ATS/QSIG and MFC R2).

The Forum on Aeronautical Software (FAS) has been established to provide a forum for those involved in the development of aeronautical software to share experiences and good practices and to provide a platform for the exchange of information regarding subjects addressed in the “software document suite”, new and emerging technologies, development methodologies, interesting use cases and other topics related to aeronautical software and related technologies.

The FAS is a joint RTCA/EUROCAE User Group that holds discussions and develops information papers called FAS Topic Papers (FTPs) relating to aeronautical software topics in efforts to harmonize these information papers. The purpose of this area of the RTCA/EUROCAE website is to provide an overview of the FAS and to provide access to selected Information FTPs. Topics typically addressed by the FAS will relate to aeronautical software, including topics covered by the following set of RTCA/EUROCAE published documents (referred to as the “software document suite”):

  • ED-12C Software considerations in airborne systems and equipment certification
  • ED-94C Supporting Information for ED-12C and ED-109A
  • ED-109A Software Integrity Assurance Considerations for Communication, Navigation, Surveillance and Air Traffic Management (CNS/ATM) Systems
  • ED-215 Software tool qualification considerations
  • ED-216 Formal methods supplement to ED-12C and ED-109A
  • ED-217 Object-oriented technology supplement to ED-12C and ED-109A
  • ED-218 Model-based development and verification supplement to ED-12C and ED-109A

Any information paper (FTP) released by FAS has been coordinated among the members of the group and have been approved by the FAS co-chairs for release. These papers do not constitute official policy or position from RTCA/EUROCAE or any regulatory agency or authority. These documents are made available for educational and informational purposes only.

 

Goals:
The goals of the FAS are as follows:

  • To share lessons learned in the use of the “software document suite” and to encourage good practices and promote the effective use of RTCA’s and EUROCAE’s publications.
  • To develop FAS Topic Papers related to subjects covered by “software document suite” or other related aeronautical software industry topics.
  • To identify and record any issues or errata showing the need for clarifications or the need for modifications to the “software document suite”.

If the FAS Executive Management Committee determines there is a general FAS agreement for proposed changes to the “software document suite” or the need for a new technology supplement, the FAS Executive Management Committee will bring this to the attention of RTCA/EUROCAE and FAA/EASA as appropriate with a request for discussion of the need for a new special committee/working group. It is expected that the efforts of the FAS would be used as input to the new special committee/working group thus the text development process would be more efficient as it would start with baseline material prepared by an expert user group.

Membership:

Initial membership of FAS is limited to the Executive Management Committee and a Technical Leaders Group plus invited members who may be able to share their experience and expertise in the discussions related to and development of FTPs. The current membership is open to employees of companies that have membership to either RTCA or EUROCAE, with an associated role of either primary or observer. The role type is based upon experience, expertise, and number of fellow company FAS members. For membership interest, see the Register of Interest link at the bottom of this webpage.

  • Executive Management Committee – comprising the Executive Management Committee Leaders identified and agreed with RTCA and EUROCAE.
  • FAS Technical Leaders Group Members are those members identified by the Executive Management Committee to assist in leading Technical Groups (TGs) that will work on specific FTPs as agreed by the FAS Executive Management Committee.

While membership is initially being managed through the Executive Management Committee, FAS is able to collect and store details of anyone wishing to Register Interest in the committee for future membership consideration.
Note that any contact and other information provided to the FAS shall be stored and maintained by the Executive Management Committee and will not be made available in the public domain.
If you are interested, click here to download the registration of interest form and upon completion, please submit it to: fas@rtca.org.

Currently there is little guidance or regulatory material published on the subject of Aeronautical System Security. In contrast, there is considerable guidance and regulatory material published on the subject of aeronautical system safety and ground systems security. As safety and security are two distinct but related concepts that interact, the WG will be required to place emphasis on their respective characteristics and dedicated domains of application.
WG-72 is developing Aeronautical System Security guidelines specifying security objectives rather than solutions in order to ensure their stability over time, addressing airborne systems and interfacing ground systems in their end-to-end relationship.
In doing so, WG-72 has adopted a holistic approach, addressing security-related topics throughout the entire lifecycle of products developed, manufactured and operated by many different civil aviation stakeholders.

WG-92 is working to maintain the current ED-92B version up to date and synchronized with other VDL standards. ED-92 is used in the baseline for the certification of the avionics systems and has to be consistent with the expectations of the European DLS-IR mandate.
In addition, while working on ED-92B which currently only contains test cases for the avionics systems, WG-92 identified the need to add test cases related to ground systems requirements in order to ensure the interoperability of the VDL Mode 2 systems.
The group has to determine what these test cases are and determine how these new test cases could be integrated in the existing MOPS.
Finally, a VDL Connection-less mode is under study by the VDL working groups as it should improve the system performances and reliability. The on-going discussions may lead to VDL standards update (ICAO 9776, ARINC 631, MASPS & MOPS) and, in that frame, ED-92B should be impacted.
In order to reach this objective, WG-92 is working jointly with the AEEC Data Link (DLK) Systems Subcommittee and the RTCA SC-214 VDL Sub-Group. Each group is in charge of a set of VDL-related documents, which are interlinked but cover different aspects.

Physical test-benches used in the aircraft development are complex platforms with high initial and recurrent costs. One means to alleviate these problems - Virtual Testing - is a promising solution that has already demonstrated its benefits in other industries (cell phone, etc.). However, in the avionics industry, it brings specific challenges: complex distributed systems, hardware heterogeneity, and multiple supplier infrastructures.
WG-97 ‘standardises’ the integration of virtual avionic components and enable the development of ‘plug and play’ virtual test benches.

Fatal accidents have occurred overwater, including Air France flight 447, in which flight data and cockpit voice recorders have been very long to recover. As the long or non-recovery of recorders greatly reduces the likelihood of the actual cause of these accidents being discovered, and in order to improve the recovery of wreckage and flight recorders following an accident or incident, ED-62A has defined a performance standard for ELTs.
WG-98 is working to update ED-62 to take into account recent developments and has created a MASPS defining the automatic in-flight triggering criteria of the ELT.
The work is carried out jointly with RTCA SC-229 Aircraft Emergency Locator Transmitters.

As the long-lasting or non-recovery of recorders greatly reduces the likelihood of discovering the actual cause of accidents, and in order to improve the recovery of wreckage and flight recorders following an accident or incident, it is necessary to improve performance standards for new-generation ELTs and their means of activation.
In addition, remote activation from the ground of ELT offers the possibility to localize in-flight a non-cooperative aircraft and therefor participate to the ICAO Global Aeronautical Distress & Safety System (GADSS) autonomous distress tracking function.
Finally, a general effort has been made to make General Aviation (GA) safer, including safety recommendations to make the complete ELT system more reliable (from the ELT unit to the antenna, including the cables) and reduce the GA distress cases where the ELT unit is operational but not the complete ELT system (unplugged antenna, damaged cables). This effort led to the development of ELT with internal/integral GNSS receiver and SAR antenna. For those integrated ELT, a remote activation from ground would be relevant for disappearance cases when the ELT is not triggered by G-switch or manually.
The subgroup will develop a MASPS for Return Link Service.

WG-103 Independent Non-Cooperative Surveillance will develop a system agnostic Technical Specification for non-cooperative surveillance sensors – supplemented as necessary with technique (multi/bi-static or mono-static, passive and/or active) or frequency specific aspects (operating spectrum will influence the clutter and target modeling) that may necessitate annexes specific to different high-level sensor types. The Technical Specification will include guidelines to assist ANSPs procuring such Systems.

Internationally, operating regulations on runway surface contamination are primarily set by the International Civil Aviation Organization (ICAO), particularly through Annexes 6, 14 and 15 of the Convention on the International Civil Aviation. The said annexes set out recommendations on the information to be given to the flight crew on the type and thickness of contaminants present on runway surfaces. In line with the approved Terms of Reference (ToR), to define the performances expected from the systems and the way of verifying that the latter reach them, WG-109 is tasked to develop Minimum Aviation System Performance Standards (MASPS) for Runway Weather Information Systems.

WG-110 will develop MOPS for Class A Helicopter Terrain Awareness and Warning Systems (HTAWS), analogous to fixed wing TSO-C151 Class A TAWS, in support of offshore helicopter operations. The justification for the tasking includes:
• Class A HTAWS is mandated for new aircraft first registered after 31 December 2018 under Commission Regulation (EU) 2016/1199 of 22 July 2016 (SPA.HOFO.160(c)). This mandate may be extended to additional aircraft by EASA Rulemaking Task RMT.0708. The MOPS are required to form the basis of a technical standard to support the air operating rule mandate.
• It has been demonstrated that Class A HTAWS (provided with the “Classic Modes” defined in UK CAA CAP 1519) can provide a significant (four major accidents in UK operations alone could have been avoided) and very cost-effective (of the order of $20k per aircraft) improvement in the safety of offshore helicopter operations, and would address a number of UK AAIB Safety Recommendations. The MOPS will promote and facilitate the introduction of appropriate HTAWS.
The focus of the WG will be on offshore helicopter operations.
