The Council of EUROCAE is responsible for approving the establishment of new Working Groups (WG) and for the definition of their work programmes, taking account of submissions made by any aviation stakeholder and in particular EUROCAE members. The Council reviews and approves all documents prior to their publication. The General Secretariat monitors the WG activities, and has initiated the Chairperson's Club in 2010 to provide the Chairpersons and Secretaries with an opportunity to learn more about EUROCAE's procedures. This event is also an excellent opportunity to meet fellow Chairpersons and Secretaries, as well as the Secretariat staff.

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.

In particular, WG-14 is scheduled to deliver the following documents:

  • ED-14revH Environmental conditions and test procedures for airborne equipment - 2019
  • ED-234revA  User Guides to ED-14G - 2019

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.

WG-49 will provide its deliverables in line with the following schedule:

ED-73F - MOPS for Secondary Surveillance Radar Mode S Transponders - Q4/2019
ED-115A  - MOPS for Light Aviation Secondary Surveillance Radar Transponders - Q4/2019

The Forum on Aeronautical Software (FAS) is a joint RTCA/EUROCAE User Group that holds discussions and develops Information Papers (IPs) 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 Papers (IPs). 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-109
  • 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 Papers released by FAS have 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.

The 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 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 Information 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.

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 IPs.

  1. Executive Management Committee – comprising the Executive Management Committee Leaders identified and agreed with RTCA and EUROCAE.
  2. 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 Information Papers 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, pleaser register here, or contact RTCA.

The proliferation and daily use portable electronic devices (PEDs) such as mobile phones, smartphones, e-readers, tablets, laptops, and media players necessitate the re-assessment of standards regarding the use of PEDs on board aircraft.  WG-99 was created to update current EUROCAE documents in this area to allow the industry and authorities to again have a common and agreed document, which will form the basis for the approval of PED and T-PED devices on board aircraft.


WG-99 published

  • ED-130A Guidance for the Use of Portable Electronics Devices (PEDs) on Board Aircraft - published December 2016
  • ED-239   Aircraft Design and Certification for Portable Electronic Device (PED) Tolerance - published December 2016


The work was carried out in collaboration with RTCA SC-234 Portable Electronic Devices.

Following completion of the work programme, the WG was disbanded.

WG-100 is tasked to develop standards for Remote and Virtual Towers, to assess previous work (eg SESAR, DFS, LFV, etc.) and develop a report that discusses the possibility of extending the scope of work beyond visual surveillance.

WG-100 has published ED-240 "MASPS for Remote Tower Optical Systems" on 29 September 2016.

In line with the current ToR, WG-100 is now developing ED-240A, a extension to the existing MASPS including target tracking technologies. Target Date is Q2/2018.

WG-102 is tasked to specify generic surveillance safety and performance requirements. These are based on operationally driven ATC surveillance requirements that are levied onto a logical end-to-end ATC surveillance function and its respective sub-functions (resembling typical physical ATC surveillance components).

In line with the current ToR WG-102 will publish the GEN SUR SPR in Q4/2018.

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 modelling) that may necessitate annexes specific to different high-level sensor types. The Technical Specification will include guidelines to assist ANSPs procuring such Systems.

WG-103 is scheduled to deliver the Technical Specification by Q4/2017.

Having reached maturity within the SESAR activities, first SWIM services are now ready for standardisation. In the area of extending the horizon of Arrival management (AMAN) a relevant SWIM service has been identified, designed and validated according to a published and applied “SESAR Method on Services”. EUROCAE WG-104 has been created to use the results of this particular SESAR activity to standardise a first SWIM service.

The SWIM service chosen is the "Extended Arrival Manager Service".

WG-104, in line with the current ToR will deliver the following documents:

  • MASPS "SWIM service covering Extended horizon AMAN coordination" - 2017;
  • Report "Lessons learned from the standardisation of the extended AMAN Service" - 2017; and
  • Report "Guidelines for standardisation of SWIM Services" - 2017.

To facilitate the operational approval path in Europe and an EASA ETSO authorization, an industry standard on EFB became necessary. Based on the existing material, WG-106 should identify the minimum requirements that any EFB application must meet and, develop corresponding test criteria, and monitor and consider the progress of the current EFB rulemaking activity at EASA.

WG-106 will deliver MOPS for Electronic Flight Bag (EFB) Software Applications - 2018.

WG-107 is tasked to revise the existing EUROCAE Document ED-57 “Minimum Performance Specification for Distance Measuring Equipment (DME/N and DME/P) – Ground Equipment” and to develop a new document “Minimum Aviation Systems Performance Specification (MASPS) for RNP Reversion using DME/DME Positioning”.

In line with the approved ToR, the following deliverables are planned:

MOPS for Distance Measuring Equipment (DME/N and DME/P (Ground Equipment); Revision A of ED-57 - Q4/2019

MASPS for RNP Reversion using DME/DME Positioning - Q4/2019

Based on the inputs from ICAO, and in coordination with the AEEC IPS and RTCA CS223 activities, EUROCAE WG-108 will be able to determine what exactly is needed to ensure the deployment of ATN/IPS. In particular, ICAO will standardize the needed features for ATN/IPS such as Security, Addressing, Mobility… This will require providing guidance to ensure a consistent end-to-end deployment.
EUROCAE WG-108 will prepare a guidance document to ensure that the ATN/IPS deployment answers to the need in terms for safety, security and performance.

Deliverable: Guidance on ATN/IPS end-to-end interoperability and certification - 2020
