SKY-Scanner: time-critical decision support system surveilling aircraft landing and take-off Kristina Lapin Vilnius University, Lithuania

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

Project background • Radars – insufficient accuracy at low altitudes • Lidar — laser radar – exact, when directly targeted INO Workshop, December 7 -9, 2010

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

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

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

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

Generalized terrain INO Workshop, December 7 -9, 2010

Proof of concept in SKY-Scanner Abstract landscape with projection curtains INO Workshop, December 7 -9, 2010 17

SKY-Scanner demo INO Workshop, December 7 -9, 2010 18

Conclusions • SKY-Scanner DSS – Provides aircraft surveillance at low altitudes – The laboratory implementation complies the third technology readiness level (TRL-3) • Decision-making scenario – Improves situational awareness – Reduces cognitive workload • Future work – User studies to validate the concept INO Workshop, December 7 -9, 2010 19
