Waypoint optimization for accurate Pseudo-RTA in descent trajectory

● Feasibility of Waypoint Optimization to realize Pseudo-RTA • Theoretical Analysis & Validation using Operation Data • Similar tendency is confirmed • Accurate Error Model & Control Model are mandatory → Future work ● Introduction STD Management into 4DT Management • Application Examples • Error STD Minimization • WP Arrangement for STD Requirement ● Future Works • STD Function of other Parameters • Altitude, TAS, Direction, Type • Seasonal Change & Weather • A lot of Assumptions in Modeling & Validation • IAS by ATC, Speed Change, etc.
