1 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Technical Aspects of OATA ACG Workshop, 17 February 2004 Bert Nijhof, Shanda Cordingley

2 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Logical Architecture Why Logical?

3 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Organisation (OCD/CONOPS) Goals: What must be done l work flows; l activities; l communication patterns. How is it done l assign (sub-) activities to systems or humans; l departments; l assign activities to departments. System (OATA) Goals: What are the Application Activities l relations and dependencies. How is it done l software programmes and modules; l computers; l networks; l interoperability standards. Recapitulation of Principles

4 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Old Approach: Main functions, function and sub-functions l radar data processing l flight data processing l flow management l avionics Current Approach: Objects, co-operating objects l Aircraft l Airway l Flight Plan l Sector l Radar l and the services they provide (e.g. FL change) ATM Application Activities

5 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky l The controller requests a FL change l The Flight Plan Object coordinates the change, since it knows which aircraft is flying the route F It will pose the question Can this aircraft fly on FL x to the Route Object; F The Route Object will ask the Airspace Object and the Airway Object, whether the actual aircraft equipage allows to fly on FL x. l The Flight Plan Object will change the FL or it will reject the change l Note that for this FL change the following operational issue must be solved: F what is the scope (current sector, current centre, remainder of the route) F when is co-ordination required e.g. FL Change

6 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky l The issues addressed are purely related to the Operational Use of the System l The process used is a formal Engineering Method; F Identify which Objects from the Operational Domain(s) should be represented in the system F Define the boundary of the responsibility of each object F What questions about themselves should those objects be able to answer (services) The result is a LOGICAL ARCHITECTURE! Operational & Engineering Skills required

7 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky OATA is concerned primarily with the ATM Application! Communication COTS Middleware User Interfaces ATM Application Logic ATM Application Technique Architecture Layers

8 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky l Translation of operational requirements in formal, unambiguous engineering language (No need for skills in theology to explain the meaning of plain text requirements during factory- and site-acceptance testing) l Close daily co-operation between the architects and operational experts is essential l Alignment of the requirements for all involved parties (ANSP, Airlines, Airports, Aircraft builders, ATC Systems Manufactures, etc.) l Alignment of the target dates for development by the involved parties through the Evolution plan l Organisation of a European wide buy-in Benefits of the Approach

9 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky OATA Logical Architecture A formal unambiguous specification of the operational behaviour of future ATM/CNS systems accepted by the stakeholders

10 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Progress 2 out of 6 Iterations have been completed.

11 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Iteration 1 l Airspace Management; F Use Case: Submit a Regional Airspace Use Plan for Feedback l Airport Operations F Use Case: Taxi-in of an aircraft l ATC and Flight Management F Use Case: File a Flight Plan F Use Case: Change Flight Intent to Resolve Conflict l Aeronautical Information Management F Use Case: Obtain Pre-Flight Update Briefing l Surveillance F Air and Ground Surveillance

12 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Use cases: l Submit ACC Capacity Plan for Feedback; l Resolve Ad-Hoc Conflicts; l Handle Aircraft Departure. Airport Operations (WP 4.2.7) Cross-Domain Modules Flight Manager (4.2.1) En-Route + TMA ATC Executive Planning (WP 4.2.2)(WP 4.2.3) Aeronautical Information Manager (WP 4.2.4) Configuration Manager (WP 4.2.8) ATFCM (WP 4.2.9) Aircraft Operator (WP ) Avionics (WP ) Aircraft Derived Data Manager (WP ) Surveillance Ground - Air (WP 4.2.5)(WP 4.2.6) some further developments substantial development completion of bottom-up work Iteration 2 - In Progress In progress Not started

17 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky System Wide Information Management Using Cross Domain Components

18 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Cross domain modules: l Ensure that everybody has the same information l Communicate updates immediately, everywhere l Ensure data ownership rights, etc l Are not just data stores but provide services F standardise the services that will access the shared data, rather than standardising the data, avoiding the risk that data will be used in a different way Consequently everybody interprets the data in the same way! Identification of data and functionality common to different ATM domains Built in Interoperability delivered by Cross-Domain Modules

19 ACG Workshop, 17 Feb 2004 – OATA and Single European Sky Cross-Domain Modules A common set of services and data and on top of that: l Domain specialisations (extensions) possible F domain-specific data F domain-specific services l Each physical system will need its own instance of these cross domain modules
