Understanding the notion of FF-ICE Service
The FF-ICE/R1 Implementation Guidance Manual, which addresses the first implementation release of FF-ICE, describes the main procedures and processes in terms of six FF-ICE services.
FF-ICE Services are defined as a function from a business perspective in a consistent manner with the definition of other services in Annex 3 (MET service), 11 (Air traffic services) and 15 (Aeronautical information services). In order to fulfil the part of the function related to the exchange of information, FF-ICE Services make use of one or more of information services, defined as “A type of service in a service-oriented architecture that provides an ATM information sharing capability.”, in accordance with the PANS-IM requirements.

This important clarification can be summarised by the following picture.
FF-ICE Services
makingprovided by NM that makes use of the NM B2B Services
Family 5.6.1 – Flight Information Exchange covers five of the six FF-ICE Services specified by ICAO ATMRPP for Release 1, namely the Filing Service, the Trial Service, the Flight Data Request Service, the Notification Service, the Data Publication Service and the Trial Notification Service. These five services, which are provided by EUROCONTROL NM, makes use of the NM B2B services to fulfil the part of the function related to the exchange of information. The picture below identifies the NM B2B services used in this context. An important element to be noted is the reuse of the NM B2B Flight Management Service (as an information service) in order to support the FF-ICE Fling Service, FF-ICE Data Publication Service and FF-ICE Notification Service, with detailed explanations captured in the subsequent table.

OR |
The NM B2B |
Filing Service has an interface based on the synchronous Request/Reply MEP that supports the filing of a new eFPL, the update to |
an existing eFPL and |
the cancellation of an eFPL |
. The synchronous reply to the filing of, or update to, an eFPL provides immediate feedback to the operator regarding whether the eFPL was successfully processed, and whether it is acceptable. Changes in |
flight plan acceptance occurring any time after the filing can be obtained either |
via the interface of the NM B2B Filing Service based on the Publish/Subscribe MEP, or in request/reply mode via the NM B2B Flight Data Request Service |
. In the former case, the NM B2B |
Subscription Management Service is used to create and manage the appropriate subscriptions to the changes in eFPL acceptance. The NM B2B Filing Service uses the FIXM data model and messages, complemented with NM extension to cover the European specificities. | ||
| Trial Service | NM B2B Trial Service | The NM B2B Trial Service |
| has one interface based on the synchronous Request/Reply MEP that supports the submission of a what-if type of request to EUROCONTROL NM to ascertain the acceptability/validity and possible ATM impact of a potential eFPL or the effects of a change being considered, without either creating a flight plan or changing the intended filed flight plan. | ||
| Flight Data Request Service | NM B2B Flight Data Request Service | The NM B2B Flight Data Request Service has one interface based on the synchronous Request/Reply MEP allowing to immediately retrieve eFPL information, including the eFPL data and the Filing Status of a previously filed eFPL (or the submission status in case of manual intervention). |
| Data Publication Service | NM B2B Flight Management Service (Publish/Subscribe interface) | The NM B2B Flight Management service |
has an interface based on the Publish/Subscribe MEP that generically supports the publication of flight data. In particular, this interface will push the eFPLs to the client applications having subscribed to the eFPL topic using the NM B2B Subscription Management Service. | ||
| Notification Service | NM B2B Notification Service + NM B2B Flight Management Service (Publish/Subscribe interface) | The NM B2B Notification Service |
has one interface based on the synchronous Request/Reply MEP that supports the submission of notifications of departure and arrival events. |
The distribution of notifications of these events to concerned stakeholders is done via the publish/subscribe interface of the NM B2B Flight Management Service. The subscription to these events are created and managed using the NM B2B Subscription Management Service. |
