• SWIM Technical Infrastructure Segmentation (i.e. Profiles)• One solution and certainly not one technology will suit all.

Different stakeholders, based on their business needs, may not have the same requirements for SWIM.

• SWIM profiles are needed to classify different types of SWIM usage permitting and to map the SWIM requirements with the potential set of supporting technologies and services options.

• SWIM Profiles are also used to assemble SWIM middleware functionality into coherent ‘right-sized’ solutions that meet the needs of the stakeholder systems.

• Need to ensure a consistent view of the flight data between ATM systems.

• It is intended to satisfy current operational needs including the European Commission Regulation (No 1032/2006) relating to notification, coordination and transfer of flights between air traffic control units, as well as to provide the basis for future operational concepts.

• iCOG projects dealing with it• Ground Industry, wide range of ANSPs and ECTRL on board.

• An EUROCAE standard as a result: ED-133• “FLIGHT OBJECT INTEROPERABILITY SPECIFICATION”

SWIM Master Class – Initiation Day14 June 2012

• Sharing Flight Object (FO) information during the execution phase of the flight between ATC systems• Each ATC system is both provider and consumer of services• Technologies have to accommodate near real-time (e.g.

requests for coordination to be served within 1 sec.) and criticality (i.e. Safety, Security, Availability, …)

• The initial work for ATC-ATC profile starts from: • Standard defined at EUROCAE (ED-133 - FLIGHT OBJECT

INTEROPERABILITY SPECIFICATION)• Open standards available from the SOA or OMG world that

provide interoperability• COTS products

• The definition is not looking for a unique fixed way to implement the ATC-ATC SWIM profile…• but setting the needed requirements for making them interoperable.

• Two prototypes are developed …• by using different open standard based COTS/OSSs whenever possible (solution

needed to be vendor independent) in order to support the validation exercise

• The ATC-ATC SWIM profile…• provides a set of needed capabilities

• allows a better sharing and accuracy of Flight information.

• is not linked to application services (changes to App Services doesn’t mean changing ATC-ATC SWIM profile.
