We are pleased to announce the publication of ED-254A “Arrival Sequence Service Performance Standard”.

EUROCAE has produced a number of deliverables in the SWIM area, including but not limited to a SWIM Service specification on an information service for AMAN extended Horizon, a template for future service standardisation within EUROCAE and a list of potential SWIM Services to be standardised. The role of WG-104 is to provide EUROCAE Working Groups with even more reliable and useful support material in form of an improved template and a comprehensive methodology to accomplish their SWIM Service standardisation activities. It is envisaged that the outcome produced will be immediately useable in the European SWIM context.

ED-254A supersedes ED-254, ‘Arrival Sequence Service Performance Standard’ (issued in July 2018). It represents one of the first SWIM service definitions produced and entered in the SWIM registry. Following early implementation experience in 2023, specific issues relating to implementability and leaving room for interpretation were identified.

ED-254A is promoting greater interoperability and improved implementability. In addition to assorted corrective and clarifying editorial updates, Revision A provides in its Appendix A a recommended implementation example building upon REST and AMQP technologies and ensuring its full and complete consistency with the service requirements. For a full record of normative changes against ED-254 see Appendix D. The Supplementary Material contains digital, machine readable artefacts from the standard.

Congratulations to the members of WG‑104 “SWIM Services” and to its leadership: Jan Stibor (LFV & SESAR Deployment Manager) and Mira Bognar (HungaroControl).
