Operational Environment

operational environment

operational needs

ATM needs to know about the occurrence or expected occurrence of specified en-route and approach weather phenomena 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 B.

This service satisfies these by offering meteorological information as regulated by Commission Implementing Regulation (EU) 2017/373 of 1 March 2017 and ICAO Annex 3.

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

Application Message Exchange Pattern

application message exchange pattern	PUBLISH_SUBSCRIBE SYNCHRONOUS_REQUEST_REPLY

Service Behaviour

service behaviour	typical behaviour	The service behaviour shall be in accordance with the patterns detailed in the Message Exchange Patterns: Identification Guidelines. The typical service behaviour, is: The service consumer subscribes to the service The service sends the latest SIGMETs to subscribers when they are available and match their subscription. The interfaces have different behaviour. A combination of an AMQP 1.0 implementation and an OGC implementation shall be used for the basic behaviour. The typical behaviour for PUBLISH_SUBSCRIBE means that: The subscription is handled by either: a request-reply implementation (see IWXXM SIGMET Subscription and Request Service Subscription Interface) or an email request to the service provider. The distribution of the messages is handled by an AMQP 1.0 implementation (see IWXXM SIGMET Subscription and Request Service Distribution Interface). The typical behaviour for REQUEST_REPLY (as used in IWXXM SIGMET Subscription and Request Service Request Interface) is as follows: Synchronous Request/Reply 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 SIGMET, the reply message, is sent from the service to the service consumer.

Service Monitoring

service monitoring	A service monitoring mechanism should be made available to service consumers.

Transversal

Support integration of existing and/or tailored weather information with operational processes to aid decision-making and improve understanding of the operational impact of adverse weather.

By service consumer role

Stakeholder/Role	Description of stakeholder/role	Needs for en-route significant weather information	Notes
CIVIL_AIRSPACE_USER	A generic term designating an organization operating aircraft and its pilots, the flight operations centres (FOC) responsible for the strategic planning of a flight and the entity responsible for the execution of a flight which is traditionally a flight deck.	Generate graphical representations of data in support of responsibilities. Ensure safe operations by responding to changes in the situation. Provide in-flight information updates. Support the operations of search and rescue Require information on unique weather constraints such as turbulence, convection, icing, etc..	This role is recognised in the SESAR Deployment Programme as a recommended service consumer of the aerodrome and en-route services.
MILITARY_AIRSPACE_USER	Airspace User under the authority of a military organisation.	Generate graphical representations of data in support of responsibilities. Ensure safe operations by responding to changes in the situation. Provide in-flight information updates. Support the operations of search and rescue Require information on unique weather constraints such as turbulence, convection, icing, etc..	This role is recognised in the SESAR Deployment Programme as a service consumer of the aerodrome and en-route services. Although the military is not obliged to use SWIM, they currently rely on civil weather information and therefore it will be essential for their operations to use SWIM-services.
CIVIL_AIR_NAVIGATION_SERVICE_PROVIDER	Any public or private entity providing air navigation services for general air traffic.	Ensure safe operations by responding to changes in the conditions of the airspace infrastructure. Require information on unique weather constraints such as turbulence, convection, icing, etc..	This role is recognised in the SESAR Deployment Programme as a service consumer of the aerodrome and en-route services. The real-time aspects will have an impact on the service architecture.
MILITARY_AIR_NAVIGATION_SERVICE_PROVIDER	Any public or private entity providing air navigation services for military air traffic.	Ensure safe operations by responding to changes in the conditions of the airspace infrastructure. Require information on unique weather constraints such as turbulence, convection, icing, etc..	This role is recognised in the SESAR Deployment Programme as a service consumer of the aerodrome and en-route services. Although the military is not obliged to use SWIM, they currently rely on civil weather information and therefore it will be essential for their operations to use SWIM-services.
AIR_TRAFFIC_SERVICE_PROVIDER	A generic term meaning variously, flight information service, alerting service, air traffic advisory service, air traffic control service (area control service, approach control service or aerodrome control service).	Support situational awareness of ACC units regarding observed and/or forecasted significant weather Support capacity planning for APP and TWR units to increase separation due to expected e.g. thunderstorms, strong winds, low visibility,…	This role is recognised in the SESAR Deployment Programme as a service consumer of the aerodrome and en-route services under the term of ANSP.
REGULATED_METEOROLOGICAL_SERVICE_PROVIDER	An office designated to provide meteorological service for international air navigation.	MET providers shall have the possibility and ability to consume needed information to perform their tasks e.g. flight briefing or to update their forecast products based on the latest weather information	This role is not recognised by the SESAR Deployment Program as a service consumer. However, it is recognised in ATM Master Plan (https://atmmasterplan.eu/data/enablers/20417016.) Moreover, looking at the EU Reg. 2017/373, a MET Service Provider has to support stakeholders and for that MET-data is needed from other MET-providers. Also such MET-data is needed for their own purpose to evaluate the correctness of forecasts.
AERONAUTICAL_INFORMATION_SERVICE_PROVIDER	A service established within the defined area of coverage responsible for the provision of aeronautical information/data necessary for the safety, regularity and efficiency of air navigation.	Not applicable
COMMUNICATION_NAVIGATION_AND_ SURVEILLANCE_SERVICE_PROVIDER	A provider of CNS services.	Not applicable	Some equipment e.g. ground radar at airports have to be shut down if the wind rises above a certain windspeed threshold to avoid damage
PROVIDER_OF_DATA_SERVICES	A public or private entity responsible for the management of a Data Service Provision (e.g. to one or several Virtual Centre).	In case a provider of data services also offers/handles MET data, the provider shall have the possibility and ability to receive the data needed
NETWORK_MANAGER	The organization responsible for enabling the optimum use of airspace and ensure that Airspace Users can operate preferred trajectories while allowing maximum access to airspaces and air navigation services.	MET providers shall provide dedicated forecast product(s) to the NM in order to support daily operations. Mainly this forecast is used for pre-planning the next day, raising awareness of the NM on any possible restrictions/slotting due to hazardous weather	This role is recognised (as ATFM) in the SESAR Deployment Programme as a service consumer of the en-route services.
AIRPORT_OPERATOR	The civilian or military agency, group or individual which exercises control over the operations of the civil airport or military airfield.	Not applicable. Currently there are special products for local warnings. Partly via the MET-Report, but also via dedicated warning messages (strong winds, temperatures below 0°, thunderstorms,….).	This role is recognised in the SESAR Deployment Programme as a service consumer of the aerodrome services.
AIRSIDE_GROUND_HANDLER	A stakeholder involved in the services necessary for an aircraft's arrival at, and departure from, an airport, other than air traffic services.	Provide information to ground handlers especially in regard to hazardous weather which might affect their operations (thunderstorms, freezing rain,..)
MILITARY_DEFENCE_CENTRE	A military defence centre. Note: these centres, e.g., check for diplomatic clearance.	Not applicable
