ER APP ATC 104 — Adapt Controller Conflict Detection and Resolution Tools to Use Enhanced Ground-Based Trajectory Prediction

Controller tools are adapted to use an enhanced Trajectory Prediction model obtained through the use of improved data (e.g. extended flight plan, downlinked aircraft parameters [Mode-S or ADS-B], met data).
Current and frequently changing aircraft kinematic parameters shall be used to improve the 4D trajectory prediction. The resulting improvement in the 4D trajectory prediction provides greater accuracy of information used by conflict detection and resolution tools.
The trajectory prediction algorithm is improved through the use of ADD such as:
- Selected altitude and vertical rate: to improve modelling of vertical maneuvers
- Air speed, true air speed: to improve modelling of ground speed and ETO calculation.
- Magnetic heading, roll angle and track angle rate: to improve modelling of turn maneuvers.
Conflict detection (aircraft to aircraft and aircraft to airspace) and resolution is adapted to the variable degree of reliability of the different sources of trajectory information.
