Task Status

This page is part of the ongoing SWIM Community of Interest discussions. The content is working material. It should not be treated as final as it is still subject to review, comment and change.

Guidance

This template allows for the documentation of service definitions based on the requirements found at: /wiki/spaces/SCOI/pages/59605116

General requirements to remember:

SWIM-DEFN-010

Service definition coverage

A service definition shall define a single service

Note: This concerns the definition of a service that can be implemented by service providers. It is not used to describe a running service - use a service description in that case.

Note: This requirement uses "define" rather than "describe".

SWIM-DEFN-020

Service definition language

The textual descriptions in a service definition shall be written in English using the spelling listed as the primary British spelling when conflicting spellings exist.

operational environment

operational needs

Air traffic management needs high quality meteorological information in order to operate in a safe and efficient manner.

The meteorological information is used in systems such as those used for aerodrome processes, airport collaborative decision making (A-CDM).

request for building a PIB
subscription for continual updates when thresholds met

ATM needs to know about the occurrence or expected occurrence of specified en-route weather and other phenomena in the atmosphere that may affect the safety of aircraft operations, and of the development of those phenomena in time and space.

A list of operational needs that this service contributes to satisfying is available in Appendix C. This service satisfies these by offering meteorological data as regulated by ICAO Annex 3.

The scope of the aeronautical data satisfies the EU Implementing Regulation 2021/116 - Common Project One.

Scope - information that is exchanged international

capabilities

The service provides high quality, up-to-date, trusted, regulated meteorological data in digital form (features) for use in air traffic management systems and other systems.
