Topic Description
Specific Challenge:

A generic principle of the SES and the SESAR programme is that, where services can be delivered in a harmonised manner, they should be done so. A Common Service is a service to consumers that provides a capability in the same form that they would otherwise provide themselves. The advent of service orientation and the use of open standards create opportunities for identifying such common capabilities amongst certain stakeholder groups and encourage their use in the de-fragmentation of ATM. Applicable to any capability supporting Air Navigation Services or their related functions, they can be provided at European, network, FAB, local or other level. The future high level architecture should offer an option for the de-fragmentation of the ATM system through the provision of harmonised or Common Services. Introducing a Common Service will change how a solution is delivered and this is likely to change organisational relationships between the stakeholders due to the provision and consumption of the new service. SESAR 2020 moves from the study phase to the examination of the business and physical impact of providing specific capabilities needed to support a Solution through the provision of a Common Service.


The Project “Common Services” aims at delivering the following SESAR Solutions:

  • Sub-regional Demand Capacity Balancing Service: the purpose of the Sub-regional Demand Capacity Balancing (DCB) Service is to facilitate an improved usage of the airspace at sub-regional level and facilitate tactical interventions when necessary, ensuring that any potential disruptions could be correctly managed. The scope also includes an AOP Common Service to facilitate the integration of AOP information into the NOP.

  • Delay Sharing Service: the XMAN Delay Sharing Service operates the AMAN functionalities within an extended horizon to provide local and overall arrival sequences for planning and tactical operational purposes in a cross border environment.

  • Trajectory Prediction Service: The function of the Trajectory Prediction (TP) Service is to compute and distribute an accurate and consistent 4D trajectory and update it as the flight progresses. The output could be used during different flight phases: to propose an initial reference trajectory in the planning phase, as input for DCM during the tactical phase or facilitate transfers during the operations phase.

  • Virtual Centre Service: The Virtual Centre Service aims to provide ATS (mainly ER/APP) within the union of airspace areas controlled by distinct ATSUs. By using standardised operating methods, procedures and technical equipment, the Service would be perceived as a unique system from the consumer’s perspective, rather than the current fragmented situation. The range and QoS of the ATS provided shall be the same as now, or even enhanced.

  • Static Aeronautical Data Service: The function of the Static Aeronautical Data Service is to provide static aeronautical data in digital form to be used by different ATM systems (e.g. Safety Nets). The output is an AIXM-compliant dataset whose subsets can be retrieved by individual requests demanding specific geographical areas, attributes or functional features.

  • Aeronautical Digital Map Service: The Aeronautical Digital Map Service provides digital maps ready to be used by different ATM systems (e.g. Safety Nets) when performing separation functions. The output is highly customizable in order to meet the different requirements from the consumers and easily convertible among different digital formats, as AIXM, GML, XML, etc.

Expected Impact:

This project will develop solutions that are expected to enhance the benefit of operational solutions, especially their cost effectiveness, by identifying opportunities to provide them through alternative organisational arrangements. This is achieved through the discovery, definition and validation of common services and their enabling elements in the operational solutions.

The main performance goal is cost-effectiveness achieved through economies of scale in in the provision of commonly required capabilities enabled by standard interfaces to the services that make them available to consumers. This will support lower overall lifecycle costs, including maintenance and training and encourage the introduction of more open markets and competition. Indirectly, the solutions developed within this project will contribute to achieve performance goals in ATM Solution projects related to: Safety, Environmental sustainability (fuel/energy efficiency, noise and emissions reduction), Capacity, Predictability and Security.
