Join WG-28 and Advance GLASS (GLS Approaches Using SBAS)
WG-28 responsible for Ground Based Augmentation Systems, is seeking contributions to the standardisation of GLASS – GLS Approaches using SBAS.
With the GLASS concept, GLS-equipped aircraft will be enabled to conduct RNP approaches down to LPV minima. Publishing corresponding RNP approaches is in line with the implementation regulation for performance-based navigation (PBN IR, Regulation (EU) 2018/1048).
With GLASS, RNP approaches can be extended to a wider range of users already equipped with GLS capability, without any modifications to the airborne receivers.
GLASS proposes the use of a GAST A GBAS based on SBAS corrections and integrity parameters, combined with a locally stored final approach segment database.
The concept can support the objectives of the PBN IR by facilitating a strategic shift towards harmonised, performance-based navigation, with the aim of saving costs, increasing airspace capacity, enhancing safety, and reducing reliance on legacy navigation infrastructure, such as barometric altimeters.
However, currently no standards for such an SBAS-to-GBAS relay as GLASS exist.
WG-28 wishes to propose an update to its Terms of Reference to move forward with the standardisation of the GLASS concept

Join WG-76 and Shape the Future of Aircraft-Based Meteorological Observations
WG-76 is responsible for Air Traffic Management (ATM) Aeronautical Information Services (AIS) and Meteorological (MET) Data Link Services. Its primary mission is to develop standards that enable the digital exchange of aeronautical and weather information between ground systems and aircraft. WG-76 works jointly with RTCA Special Committee SC-206, ensuring harmonized standards between Europe and North America and supporting worldwide interoperability.
WG-76 wishes to develop 2 new standards for aircraft-based observations (ABO)
- Minimum Operational Performance Standard (MOPS) for water vapour sensors
- Operational Services and Environment Definition (OSED) for onboard weather radar systems providing data link meteorological observations
The MOPS for water vapour sensors will provide a set of performance requirements for airborne water vapor measurements. It will be used by sensor and avionics manufacturers to ensure that aircraft-based water vapor sensors meet the minimum requirements for all meteorological applications, and particularly those related to contrail detection and prediction. The MOPS will specify the data resolution and accuracy needed for water vapor and temperature measurements and will include the requirements for the downlinking and sharing of the data in real time.
The OSED for onboard weather radars will define the concept of operations and data link architecture for the downlink of fundamental radar data and meteorological observations derived from aircraft-installed weather radar systems, including turbulence, precipitation, and related parameters. It will be used by sensor, aircraft, and avionics manufacturers, and airlines, to define the concept of operation for the downlinking and sharing of weather radar data in real time for aviation and meteorological applications.
WG-76 is looking for experts in the following areas to express support for the new MOPS and OSED:
- Airlines
- Aircraft manufacturers
- Avionics manufacturers
- Data link service providers
- Meteorological services
- Sensor manufacturers

Discover WG-112 and Help Advance VTOL Handling Qualities Verification
WG-112 is responsible for Vertical Take-Off and Landing and is seeking authors, technical contributors, and supporting companies to participate in an update to ED-295 – Guidance on VTOL Flight Control Handling Qualities Verification.
ED-295 was developed by WG-112 and approved by EUROCAE on 19 July 2024 as the first edition of this guidance document.
Since its publication, the global eVTOL industry has experienced significant progress in the development, flight testing, and certification of a wide range of aircraft concepts and configurations. Numerous eVTOL manufacturers have advanced their handling qualities assessment, flight test, and certification activities, generating valuable lessons learned and practical experience.
As a result, there is a clear need to update ED-295 to reflect these developments and incorporate the latest industry knowledge and best practices.
In parallel, SG-4 Deliverable ED-342 – Guidance on Using Simulation in Handling Qualities Certification of VTOL has reached the final approval stage. Alignment between ED-342 and ED-295 is therefore necessary to ensure consistency across the guidance material. The update will also consider the outcomes of the extensive EASA–FAA harmonisation activities conducted in recent years, as appropriate and consistent with the regulatory agencies’ current engagement strategy.
The proposed activity will revise the guidance material supporting Handling Qualities verification from ED-295 and expand upon the Means of Compliance (MoCs) referenced in MOC.SC.VTOL. The revised document will provide enhanced guidance to support compliance demonstrations and certification activities for VTOL aircraft.
The update will be conducted in parallel with ongoing aircraft development and certification programmes, providing an opportunity to incorporate experience from flight test evaluations, certification activities, simulation, and lessons learned from applying ED-295.
EUROCAE therefore invites experts from aircraft manufacturers, system suppliers, flight test organisations, authorities, academia, and research institutions to contribute to the development of a harmonised, industry-supported approach to eVTOL Handling Qualities verification.

Join WG-115 and Develop Counter-UAS Interoperability Standards for Airports
WG-115, responsible for ,Counter UAS and is seeking new contributions to the next phase of standards development for Counter-UAS (C-UAS) systems, with a focus on interoperability requirements for systems used in the airport environment.
The work will address the need for real-time and high-quality data transmission from non-cooperative sensor systems used for the detection of UAS. It will define minimum interface requirements and an interface description for integration with existing airport and partner systems, including the display and alerting of UAS.
The activity will also consider the effects and performance of typical C-UAS defeating capabilities and their impact on existing airport and Air Navigation Service Provider (ANSP) systems, with the aim of deriving the corresponding interoperability requirements.
The standard will consider the detection, tracking, and identification functions of C-UAS systems, together with neutralisation functions and their compatibility with existing airport and ANSP systems.
If you are interested in contributing, please contact the responsible Technical Programme Manager Alex Milns.
Discover WG-130 and Support ATM/ANS Equipment Attestation Standards
The publication of Regulation (EU) 2023/1768 establishes requirements for the attestation of ATM/ANS systems and ATM/ANS constituents (ATM/ANS equipment), supporting the safety performance and interoperability of civil aviation ground equipment.
To support this new framework, detailed technical and operational standards developed by EUROCAE are to be used as a means of compliance for ATM/ANS equipment attestation and ATM/ANS operations.
WG-130 is tasked with identifying gaps and facilitating the development of standards and related deliverables, including a coordinating role in consolidating standards developments by other existing EUROCAE Working Groups, to support the attestation of ATM/ANS equipment and ATM/ANS operations.
WG-130 performed an assessment of missing equipment standards and the fitness for purpose of existing standards, as highlighted in EUROCAE Report ER-049, published in January 2026. The assessment was not complete, and the WG is currently completing this assessment to cover standards in the missing fields.
The WG will also perform an assessment of the fitness for purpose of standards as input to RMT.0744, before recognising such standards in future issues of Detailed Specifications.
The current assessment covers standards used in the design of ground equipment in the following areas:
- Remote Tower Systems
- Ground Radios
- Controller Working Positions
- Meteorological equipment, including sensors and weather radars
