Airport Collaborative Decision Making (CDM) is an important enabler of Air Traffic Management (ATM) capacity and efficiency. The concept of Airport CDM does not imply any particular system or architecture. Rather, it is an approach to using aeronautical data, based on sharing data between all Partners, ensuring a common view of the ATM and airport environment on all levels. Airport CDM also addresses the need for operational decisions to be made collaboratively thus providing a substantial contribution to maximising capacity and efficiency.

Although Airport CDM is applicable to all phases of flight, the Airport CDM concept has seen its first prototypes and trials at airports and this document is therefore dedicated to Airport CDM. An Airport CDM Task Force was created under the EATM Airport Throughput Business Division (APT) of EUROCONTROL, and documents created by this Task Force have contributed significantly to the development of this document.

Airport Collaborative Decision Making is about improving the way operational Partners at airports and the European ATM network work together at an operational level.

The quick development of the Electronic Flight Bags (EFBs) use over the last years was such that they became a very common and important tool for flight operations and have replaced paper in most cockpits.

Increasingly present, EFBs also feature more and more advanced functions that depart from the simple replacement of paper while offering new possibilities to enhance flight operations and information available to the flight crew. Consequently, EFB applications and their hosted functions become more complex to evaluate and to approve for use in operations by the national aviation authorities.

This industry standard provides a systematic and comprehensive means to address the design, development, evaluation and validation of the EFB applications proportionally to the safety risk of their intended use in flight operations.

This document was initiated to improve the capability to manage external services that affect UAS operations, as a means to support safety in the Specific Category. Considering that the GNSS receiver is the primary navigation sensor for most UAS, the level of performance of GNSS services, and especially multi-GNSS, has a direct relation with flight safety for UAS, both in nominal and non-nominal conditions according to the particular operational context where it is used. The term “multi-GNSS” is used since there are several GNSS constellations that could be used to provide positioning information to UAS. This document details some specific constellations/systems/signals due to legacy reasons, global coverage and general public accessibility. The resulting standards will support UAS operators in achieving approval for specific operations in regards to the inherent safety risks associated to the use GNSS services in UAS operations.

Revision A of ED-256 MOPS for ACAS Xa with ACAS Xo Functionality will integrate Change 1 into the core specification and will implement a number of change proposals collected during initial implementations and the development of other ACAS X Variants.

ED-256 consists of two Volumes plus supplementary material:

Volume I: MOPS for ACAS Xa with Xo Functionality
This document sets forth minimum operational performance standards for the Active (Xa) and special Operations (Xo) system variants of Airborne Collision Avoidance System X (ACAS X) equipment.
ACAS X is intended to improve air safety by acting as a last-resort method of preventing mid-air collisions or near mid-air collisions (NMAC) between aircraft. By utilizing surveillance information from Secondary Surveillance Radar (SSR) and ADS-B technology, ACAS X equipment operates independently of ground-based aids and air traffic control (ATC). Aircraft equipped with ACAS X have the ability to interrogate airborne transponders and receive ADS-B Messages to determine the location of other aircraft in the vicinity and assess the risk of collision.

Volume II: Algorithm Design Description (ADD)
This document provides the Algorithm Design Description (ADD) for the Surveillance and Tracking Module (STM) and the Threat Resolution Module (TRM) of the next generation Airborne Collision Avoidance System (ACAS X). The algorithms are described at a sufficiently high level to allow for implementation in a variety of software languages and hardware platforms, thereby providing maximum freedom to manufacturers while ensuring the intended output from the system. This document provides descriptions of the algorithm’s operations.

Update the definition of the D-ATIS Data Link Service such that it allows the transmission of the extended length messages of the ICAO Global Reporting Format (GRF).

ED-89A describes the requirements for a Data Link Service providing D-ATIS data over ACARS. One of the requirements stated in ED-89A is a maximum message length of 800 Characters.

ICAO has developed a new format for the reporting of runway conditions as part of ATIS: the GRF (Global Reporting Format). Because of the new structure and additional reporting requirements, ATIS messages can become significantly longer (in particular for complex aerodromes in adverse weather conditions). Taking into account the requirement for D-ATIS messages containing identical information as Voice ATIS, this will result in a increase of the length of D-ATIS messages beyond 800 characters.

Investigation across manufacturers and Data Link Service Providers (DSP) showed that most avionics can cope with longer D-ATIS messages and that the ACARS Data Link should be able to transmit those messages. However, the DSPs were not certain that this can be achieved respecting all requirements stated in ED-89A.

Therefore it was not possible to simply increase the maximum message length. Rather the reservations of the DSPs were covered in a note added to ED-89A.

The Change 1 to ED-89A has to be considered as complementing ED-89A by opening the possibility for D-ATIS message to be longer than 800 characters.

This document provides processes used to develop civil aircraft and systems. It has been revised to incorporate known errata and specific industry comments necessary to maintain the recommendations consistent with industry state-of-the-art.
The guidelines herein are industry best practices for the development of aircraft and of systems. Modern aircraft typically comprise a large integrated environment consisting of multiple systems with significant dependencies and interactions. Frequently portions of these systems are developed by separate individuals, groups, or organizations. These systems require design discipline and systematic development to ensure that safety and operational requirements can be fully realized and substantiated. Adherence to these guidelines is recommended for development of all aircraft systems, especially those that may contribute to failure conditions with the potential to affect safety.
Work carried out jointly with SAE S-18.

Implementing Regulation (EU) 2019/947 mandates in its Article 15 that “when Member States define UAS geographical zones, for geo awareness purposes they shall ensure that the information on the UAS geographical zones, including their period of validity, is made publicly available in a common unique digital format”.

EASA AMC&GM to (EU) 2019/947 Article 15 provides additional considerations about the related data quality, as well as a reference to Chapter 8 ‘UAS restriction zone data model’ of the EUROCAE ED-269 as AMC for the common unique digital format.

Additionally, Annex V of Implementing Regulation (EU) 2021/664 on U-Space requires that exchange of relevant operational data and information between U-space service providers and air traffic service providers is made through an exchange model for which the data model included in ED-269 is considered as a very good foundation. Yet, the model as currently set in Chapter 8 of ED-269 will need to evolve to be compatible with new objects and features associated to a scope wider than geo-fencing, e.g. dynamic airspace reconfiguration.
Finally, the implementation of (EU) 2019/947 is raising requests for improvements or additions to the data model and format currently included in ED-269.

Considering that all the necessary evolutions of ED-269 Chapter 8 data model are not linked to the geo-fencing MOPS itself (i.e. the actual scope of ED-269), it was considered relevant to develop a dedicated Technical Specification. The Technical Specification for Geographical Zones and U-Space data provision and exchange will cover all aspects related to Data Provision and Exchange (i.e. data scope, quality requirements, data format and model, exchange of data through information service) in support of regulations (EU) 2019/947 and (EU) 2021/664.
