Research Objectives

• Construct self-organized trajectory-based operations system for small aircraft, and demonstrate by flight experiment with multiple aircraft.

Operations Concept

• Based on shared state vector and intent (trajectory), approaching traffic are self-sequenced and separated without controller.

• The CDTI finds conflict-free trajectory and advices pilots. Once the trajectory is assigned, ref-speed is advised to keep separation.
