2. FP6 project title: “Development of an Innovative LIDAR Technology for New Generation ATM Paradigms” Work package 9: 1.Modelling paradigm 2.Model and data definition features 3.Model and data management features 4.Analytical methods and visual representations 5.User interfaces 6.Model and data interchange features INO Workshop, December 7-9, 2010 2

3. Project background Radars –insufficient accuracy at low altitudes Lidar — laser radar –exact, when directly targeted

4. INO Workshop, December 7-9, 2010 Current displays 2D screen –location –directions Altitude and velocity –as texts

5. Time-critical decision support Human cognitive processes –Encoding, inference, maping, application, response Decision support models –Rational (logical, analytical) An optimal solution, but requires to calculate the utility of each alternative –Naturalistic (action-based, recognition-primed) An acceptable solution, when mathematical calculations are not feasible INO Workshop, December 7-9, 2010

14. SKY-Scanner Decision Support Scenario A soft control area –the collision risk between the airplanes is tracked –the altitude is controlled; A strict control area –a landing procedure is assigned to the track –the constraints are followed. INO Workshop, December 7-9, 2010 14

15. SKY-Scanner method Strict area Required trajectory Aircraft position INO Workshop, December 7-9, 2010
