4. STF293 Status Report Background • The SES regulations establish • the essential requirements; • stipulate the stakeholders’ commitment and secure their compliance, by means of • the associated Implementation Rules (IR) • the European Community Specifications (CS) and • taking account of operational and technical developments. Hartmut UhrziNFOSYS-ATM 4

5. STF293 Status Report The EC has issued a preparatory interoperability Mandate, to the three European standardisation bodies CEN, CENELEC and ETSI. The Mandate objective is to develop European Standards for Interoperability in the European Air Traffic Management Network. This Mandate includes a list of priority CSs. EUROCAE and Eurocontrol will be associated with this standardisation work. Hartmut UhrziNFOSYS-ATM 5

6. STF293 Status Report Scope of STF 293 Task • Initialisation • Productionof an inventory of all CNS/ATM systems and their constituents which may need standardisation. In this process identify • suitable know-how for the establishment of such standards, • related organisations working at related issues, and • defineexisting ‘gaps’ to be closed in line with the given priorities. • Development of the Proposed Work Programme • Management of related activities and co-ordination with stakeholders, in particular with EUROCONTROL and EUROCAE Hartmut UhrziNFOSYS-ATM 6

7. STF293 Status Report Results of initial work steps of STF293 (1) • Draft Inventory • This inventory is a large data collection MATRIX set up with Excel • The matrix shows among other attributes • the relevant Community Specifications (CS), • a short description, • the related organisations currently working on these issues, (ICAO, EUROCAE and EUROCONTROL), and • existing helpful documentation. • Also a a few IRs have been listed where CS are directly related to IRs • (As STF 293 does not deal with IRs, these were included to give a logical overview). The inventory also identifies which CS were included in Mandate 254, those listed in ICB document 2/3, and a some defined by the STF. Hartmut UhrziNFOSYS-ATM 7

8. STF293 Status Report Results of initial work steps of STF293 (2) • Discussions on inventory issues • Some of the CS were found to have a possible bearing on the SESAME definition phase. So the EC may expect to be asked to set the priorities accordingly if the rationale provided by the STF will convince the ICB. (One example being the CS on Middleware.) • Other experts have argued that as SESAME is tasked to define standardisation requirements needed to enable the development or implementation of SES ATM systems, ETSI should refrain from spending any effort on these issues. • Also it was argued that in many of the 8 domains the specification work will need more time to become ‘mature’ enough to become a standard.

11. STF293 Status Report Results of initial work of STF293 (3) • STF 293 concludedto produce a comprehensive inventoryof the wide CNS/ATM domain, showing • the current status of on-going work, and • the open issues • The final result will show the extent of the work required. • The next work steps will concentrate on defining the ‘gaps’. • The Commission is expected to set the appropriate priorities. • Question:Does the Commission intent that ETSI investigates potential CS in all the 8 ATM areas which are considered relevant by the ETSI STF? Hartmut UhrziNFOSYS-ATM 11

12. STF293 Status Report Results of initial work of STF293 (4) • At this stage the STF believes that the work plan might be categorised as follows: • CS to be established before SESAME starts, • CS to be established parallel to and in liaison with SESAME, and • CS to be resolved after the SESAME standardisation requirements will be available. Hartmut UhrziNFOSYS-ATM 12

13. STF293 Status Report • The drafting ofEuropean Community Specifications implies the commitment of stakeholders to implement these standards. 13 Hartmut UhrziNFOSYS-ATM

15. STF293 Status Report Rule setting: The Interoperability Regulation provides the framework for the SES interoperability rules and specifications. Very high level requirements, known as ‘Essential Requirements’, for each of the 8 domains have been identified in Annex II of the Regulation. These requirements are mandatory and must be taken into account by all ATM stakeholders. The more detailed technical and procedural rules, which build on the essential requirements, basically define WHAT should be done. These are referred to as ‘Implementing Rules’ (IRs). IRs will be developed whenever necessary by Eurocontrol under mandates from the EC. These rules need to be agreed by the majority of Member States of the EU before becoming mandatory in Community Law. Hartmut UhrziNFOSYS-ATM 14R

16. STF293 Status Report Specification setting: This second level second level creates the technical specification for the system setting out in detail HOWit shall be achieved. These are called ‘Community Specifications’ (CS). According to preamble 11 of the Interoperability Regulation, compliance with published CS, creates a presumption of conformity with the Essential Requirements and the relevant IRs for interoperability. This is one of the major features of the “New Approach”: CS remain voluntary and provide flexibility for industry as other solutions may be available. CS are produced by European standardisation bodies (CEN, CENELEC, ETSI) in conjunction with EUROCAE and by Eurocontrol in accordance with Community standardisation procedures. Hartmut UhrziNFOSYS-ATM 15R

17. STF293 Status Report Conformity assessment:The third level relates to the demonstration of compliance to the Essential Requirements and Implementing Rules. This is a new mandatory requirement affecting manufacturers of products and air navigation service providers and will result, eventually, in a certification process which declares that the ground ATM system conforms to the interoperability requirements. The European Commission (EC) has issued three interoperability mandates to Eurocontrol for the development of three draft IRs. Hartmut UhrziNFOSYS-ATM 16R

18. STF293 Status Report • The European Commission (EC) has issued three interoperability mandates to Eurocontrol for the development of three draft IRs.These relate to: • Flight Message Transfer Protocol, • Initial Flight Plan and Coordination and Transfer. • The Eurocontrol Agency is providing advice to the European Commission regarding performance, safety and interoperability requirements, conformity assessment reviews and planning. The Agency is also tasked with the development of functional strategies for most of the systems identified in the European Air Traffic Management Network. Hartmut UhrziNFOSYS-ATM 17R
