Digital NOTAM Subscription and Request Service 01.00.00
Abstract
The Digital NOTAM Subscription and Request Service allows the service consumer to get aeronuatical information in accordance with the Digital NOTAM specification. The aeronautical information conforms to the event scenarios that are supported by Digital NOTAM such as runway closures. The service consumer may subscribe to the service, specifying the event scenarios of interest. It is also possible to send a direct request to the service to get the aeronautical information. The information returned is in the form of an AIXM 5.1.1 message. This supports the integration of the latest information into an existing aeronautical information store in the various ATM systems.

Operational Needs
Air traffic management is defined by ICAO as the "dynamic, integrated management of air traffic and airspace including air traffic services, airspace management and air traffic flow management - safely, economically and efficiently - through the provision of facilities and seamless services in collaboration with all parties and involving airborne and ground-based functions".
Stakeholders involved in air traffic management need aeronautical data concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential for flight operations.
This service satisfies this need by allowing clients to subscribe to event scenarios and to be notified when the aeronautical data described in the event scenario is affected.
The aeronautical data can be used, e.g., in pre-flight information bulletins. It can also be used to improve decision making thus positively impacting the efficiency of their planning and flight executions, enabled through automatic data verification and graphical visualisation. The aeronautical data is also used in other systems such as those used for airspace reservations (ARES). A list of these is available in Appendix C.
This service satisfies this need by offering the aeronautical data (in the form of event features) as regulated by ICAO Annex 15 - Aeronautical Information Services.
The scope covers the event encodings outlined in the Digital NOTAM Specification including aerodrome data for the 18 airports listed in EU Implementing Regulation 2021/116 - Common Project One.

Capabilities
The service offers subscription and request capabilities to distribute aeronautical data based on event scenarios.
Functionality
The service consumer shall be able to subscribe/unsubscribe to topics in order to receive information based on an event scenario(s).
The service consumer shall be able to request aeronautical information in the form of a Digital NOTAM.

The service shall ensure that satisfactory authorisation is put in place according to EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile requirement SWIM-TIYP-0070.
The service shall ensure point-to-point confidentiality in accordance with EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile through the use of Transport Layer Security (TLS) 1.2 or above.
The service shall ensure point-to-point integrity in accordance with EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile through the use of Transport Layer Security (TLS) 1.2 or above.

Quality Of Data
The aeronautical data offered by the service shall satisfy the applicable sections of Commission Implementing Regulation (EU) 2017/373 of 1 March 2017.
The aeronautical data offered by the service shall be encoded according to the event scenarios given in the Digital NOTAM Specification.
The aeronautical data offered by the service shall apply the AIXM 5.1.1 coding guidelines. This includes:
- Common Coding Guidelines
- Technical Coding Guidelines

Information
Information Definition
The service shall expose the event scenarios found in Appendix B. These reflect the Digital NOTAM Specification.
The event scenarios use features that are in the Aeronautical Information Exchange Model (AIXM) 5.1.1 and the AIXM Event Extension.
The AIXMBasicMessage that is returned by the service shall contain an event feature and the related AIXM features and time slices.
The event scenarios use features that are in the Aeronautical Information Exchange Model (AIXM) 5.1.1 and the AIXM Event Extension.
The AIXMBasicMessage that is returned by the service shall contain an event feature and the related AIXM features and time slices.
Filtering
The Digital NOTAM Subscription and Request Service Request Interface shall support filtering based on the operators defined in the OGC Filter Encoding 2.0 Encoding Standard. The temporal extension (WFS-TE) shall be used to support advanced temporal filtering. As a minimum use case number 4 (Retrieve the BASELINE of a feature valid at a point in time) shall be supported. The other uses cases should be supported.
The Digital NOTAM Subscription and Request Service Subscription Interface shall allow for the selection of event scenarios of interest. These should be organised around e.g. a specific aerodrome or airspace. The considerations given in the General Principles for the Digital NOTAM will help AISP organise the event scenarios.
Source of Information
The service provider shall ensure that the aeronautical data offered by the services is received from the appropriate authorised originating sources. This includes:

- CIVIL_AIR_NAVIGATION_SERVICE_PROVIDER,
- MILITARY_AIR_NAVIGATION_SERVICE_PROVIDER,
- AIR_TRAFFIC_SERVICE_PROVIDER,

Technical
Service Monitoring
A service monitoring mechanism shall be made available to service consumers.
Behaviour
The service behaviour shall be in accordance with the patterns detailed in Message Exchange Patterns: Identification Guidelines.
The two interfaces have different behaviour. A combination of an AMQP 1.0 implementation and an OGC Web Feature Service 2.0 Interface Standard implemetation shall be used for the basic behaviour.
The typical behaviour for PUBLISH_SUBSCRIBE means that:
- A request-reply implementation handles the subscription. See the Digital NOTAM Subscription and Request Service Subscription Interface.
- An AMQP 1.0 implementation handles the distribution of the messages. See the Digital NOTAM Subscription and Request Service Distribution Interface.
For SYNCHRONOUS_REQUEST_REPLY (used in the Digital NOTAM Subscription and Request Service Request Interface), the typical behaviour is as follows:
- The request message is sent from the service consumer to the service
- The service consumer remains blocked while awaiting the reply
- The service remains blocked while processing the reply
- The AIXM Basic Message, the reply message, is sent from the service to the service consumer.
