4. COST ES0802 MC/WG Meeting > 20 – 21/09/2010 Slide 4 Simulation environment DLR Traffic Simulator

5. COST ES0802 MC/WG Meeting > 20 – 21/09/2010 Slide 5 Investigated parameters (1) UA Types HALE: High Altitude Long Endurance MALE: Medium Altitude Long Endurance Altitude HALE: 41.000ft (12500m) MALE: 25.000ft (7500m) Climb strategies HELIX: Climb in a helix-like structure above the airfield / airport DIRECT: Climb along the cruising route

6. COST ES0802 MC/WG Meeting > 20 – 21/09/2010 Slide 6 Investigated parameters (2) Separation Horizontal: 5NM, vertical: 1000ft (today’s standard) Horizontal: 10NM, vertical: 1500ft Horizontal: 10NM, vertical: 2000ft Variation of takeoff time between 5:00 am and 10:00 pm in steps of twenty minutes Different mission scenarios have been investigated: National: Schleswig/Jagel ► Ingolstadt/Manching International: Schleswig/Jagel ► Paris - Orly National (civil):Egelsbach ► Schleswig/Jagel

10. COST ES0802 MC/WG Meeting > 20 – 21/09/2010 Slide 10 Results (4) Relevance of takeoff time

11. COST ES0802 MC/WG Meeting > 20 – 21/09/2010 Slide 11 Results (5) Relevance of takeoff time

12. COST ES0802 MC/WG Meeting > 20 – 21/09/2010 Slide 12 Conclusion Number of conflicts is highly depending on Selected altitude Climb strategy Departure airport and surrounding airports Crossing of highly frequented ATS routes Recommendation is depending on the mission scenario Simulation shall be used to create an assistive mission planning tool for integration into DLR’s Generic Ground Control Station efforts

13. COST ES0802 MC/WG Meeting > 20 – 21/09/2010 Slide 13 GCS mission planning tool Extension to existing DLR simulation environment Requires input of important parameters Waypoints Traffic data Payload Take-Off time Cruise altitude Simulation checks for potential conflicts based on given parameters Recommendations of solutions if high conflict potential is found
