1. 1 Airborne Programme by E. Bailey, Airborne Project Leader EUROCONTROL

2. 2 Projects l Experimental 4D Flight Management System (EFMS) l Airborne Human Machine Interface (AHMI) l Air/Ground Integration via Data Link

3. 3 EFMS & AHMI Functionality l EFMS l Prediction of 4D trajectories l Trajectory negotiation with ATC over data link l 4D Guidance l Support advanced Airborne HMI l AHMI l Interactive Navigation Display l Graphical editing of trajectories

4. 4 Project History l Activities of the Research Establishments l Arrival Managers - CENA, DLR l 4D Descents - DERA l Automated ATC - EEC l Conflict Detection - NLR l Advanced Cockpit Displays - DERA, NLR l GARTEUR Concept l Requirement for Experimental 4D FMS l Birth of PHARE

5. 5 Difficult points to be resolved 1. Generic FMS & AHMI

6. 6 Difficult points to be resolved 2. Software Engineering Aeronautical engineers software engineers Aeronautical engineers software engineers l Dispersed development sites l Software development tools l Common programming language l Need for software integration team Software engineers aeronautical engineers Software engineers aeronautical engineers

7. 7 Difficult points to be resolved 3. Integrated ATM ? l Lack of system design l Air, Ground and Comms. projects developed independently l Lack of understanding between players l Air, Ground and Comms. developers incognisant of each others operational requirements, procedures and capabilities

8. 8 Difficult points to be resolved 4. Data Link l Requirement l Flexible, high bandwidth data link l Available l Rigid data structure and protocols + complex data structures for air and ground interfaces + low bandwidth data link = poor performance l Essential to minimise the amount of data transmitted

9. 9 Success ! l Demonstrated concept of an Air/Ground Integrated ATM system l Demonstrated capability of aircraft to predict, negotiate and fly 4D trajectories l Demonstrated Advanced AHMI concepts l Spin-off to other programmes l FREER Flight l AFMS/AATMS l Avenue

10. 10 Open issues for the future l Data Link Bandwidth l Current applications for D/L require low/medium bandwidth l Need to define user requirements for the longer term l Benefits of 4D Navigation ? l Time control : Air or Ground ? l Increased capacity and reduced delays ? l Cost? l Implementation Plans l 5 year development + 7 year notification l 2012 earliest

11. 11 How further work will be undertaken. l Develop close links between Navigation, Communication and ATC domains l CBA l Fast time simulations l Real time simulations l Safety studies l Pre-operational Trials l Arrival & Departure Managers l RNAV procedures in TMA l ARINC 702A developments
