Applicable implementation requirements

CP1 requirements

Clarifications from the SDP

The SESAR Deployment Programme explains that ANSP shall:

• Consume the eFPL via the Data Publication Service using the NM B2B services in support of information Exchange of FF-ICE;
• Consume the Flight Data Request Service, using the NM B2B services in support of information Exchange of FF-ICE;
• Consume the Notification Service using the NM B2B services in support of information Exchange of FF-ICE.

The next chapters provides ANSPs with guidance to achieve these goals.

Guidance for Consuming the eFPL via the Data Publication Service using the NM B2B services.

Business justification

The eFPL content can be leveraged by the ANSPs in order to perform improved trajectory prediction for a variety of ATM functions. This would include (non exhaustive list):

• Balancing demand against capacity more accurately
• Providing complementary feedback in response to the distributed eFPLs, i.e. being able to fine-tune the 4DT portion applicable to their AOR;
  
  • See also Implementation Strategy for FPFDE NFPM, chapters 3.3 Pre-Departure Phase – Flight Planning and Filing and 4.1 Finalising the flight planning/filing phase with an Agreed Trajectory
• Facilitating AUs’ adherence to their preferred trajectories as much as possible, leading to more efficient and sustainable flights.

Which NM B2B R27 services to use?

Consume the eFPL via the Data Publication Service using the NM B2B services means

• Subscribing to the Pub/Sub interface of the NM B2B Publication Service in order to receive the eFPLs filed by the eAUs and accepted by NM.
• Consuming the interface of the NM B2B Publication Service based on the synchronous Request/Reply MEP to manage the corresponding subscriptions.

Which eFPL information will ANSPs receive?

eAUs will file eFPL using the NM B2B Filing Service. NM will use the desired trajectory and the performance data provided by the eAU for the initial trajectory calculation. This profile will go through NM validation where some adjustment might be needed so that applicable restrictions are respected. It is the resulting eFPL with the agreed trajectory computed by the IFPS that will be distributed to ANSPs via the pub/sub.

The eFPL distributed to ANSPs will therefore contain:

• the agreed trajectory computed by the IFPS
• the performance profile and take-off mass, as provided on input to NM by the eAU
• TODO

Guidance for Consuming the Flight Data Request Service, using the NM B2B services.

Business justification

CP1 mandates ANSPs to consume the eFPL via the Data Publication Service and to consume the Notification Service, using the NM B2B services. As a result, ANSPs will start receiving FF-ICE Messages relevant to their operations, including eFPLs filed by Airspace Users and approved by NM, and at a later stage FF-ICE Departure and Arrival Messages for the concerned flights. These messages will be pushed to ANSPs by the Publish/Subscribe interface of the NM B2B Services and will have to be correlated using the GUFI. In certain non-nominal situations, when for instance pushed messages expire before they are consumed by the client application, ANSPs might exceptionally receive FF-ICE Messages that cannot be correlated to an eFPL, or may be uncertain regarding the status of a given flight. In these situations, the ANSPs are expected to obtain the latest eFPL (& GUFI), or the latest flight status information, using of the Flight Data Request service provided by NM.

Consuming the Notification Service using the NM B2B services means

• Consuming the NM B2B Notification Service for submitting FF-ICE Departure and Arrival messages for flights for which an eFPL has been filed.
• Subscribing to the Pub/Sub interface of the NM B2B Flight Management Service in order to receive notifications of departures and arrivals of flights for which an eFPL has been filed.
