Introduction

The Aeronautical SWIM Services constitute a family of information services for:

satisfying the information exchange requirements of the EU Implementing Regulation 2021/116 - Common Project One (CP1) and the SESAR Deployment Programme by end 2025;
publishing, discovering and retrieving digital data sets as defined in ICAO Annex 15 and PANS-AIM; and
meeting other operational needs.

This collaborative space contains:

an entry for each information service including:
- a service definition; and
- supporting material to promote a better understanding of the service definition where needed.
"transversal" supporting material (e.g., the Aeronautical SWIM Services Ecosystem) to promote a better understanding of the services as a whole.

Organisation

Each service definition follows the same Service definition template . This allows them to be compared with other service definitions.

Services and their capability

The implementation of these information services provides the following capabilities:

the Aeronautical Information Request Service allows a service consumer to access aeronautical information;
the Aeronautical Aerodrome Map Request Service allows a service consumer to access aeronautical aerodrome maps;
the Digital NOTAM Subscription and Request Service allows a service consumer to subscribe and access aeronautical information in the form of digital NOTAM;
the Aeronautical Data Set Request Service allows a service consumer (data set user) to access data sets that have been published in the data set store;
the Aeronautical Data Set Subscription Service allows a service consumer (data set user) to subscribe to data sets or data set series within a data set store and be notified of changes;
the Aeronautical Data Set Management Service allows a service consumer (data set provider) to publish and manage data sets together with the accompanying metadata;
the Aeronautical Simple Feature Request Service allows a service consumer to access features that are customised and assembled from aeronautical information for use in Geographical Information System (GIS) systems.

An overview of the three Aeronautical Data Set services is illustrated below.

This, in turn, feeds into the following diagram with the other services.

The service design is based on some key principles:

the service definitions are standalone and independent of each other - no relationships have been defined between them;
the service definitions do not affect how the aeronautical information service provider (AISP) receives inputs or structures its information store;
the services have to be understood alongside the data set store foreseen as part of the Digital Data Set service architecture.

In addition, the following assumptions are made:

the work taking place at ICAO level on the future of NOTAM is to be reflected in the Digital NOTAM Subscription and Request Service;
the digital NOTAM concept assumes the integration of the latest information into an existing aeronautical information store in the various ATM systems;
the service definitions build on previous work undertaken in SESAR. They aim to reflect an agreed base that can be implemented in the 2025 time frame.
