contribution to opstimal

As project leader of the fuel efficiency sub-project (HAP1) PACE and its partners are developing methods to improve the operational efficiency through inflight optimization of the vertical trajectory. Building on technologies like Electronic Flight Bag (EFB), Aircraft Connectivity, IP Connectivity und Cloud Computing the vertical profile is continuously re-optimized during flight based on current aircraft and weather data as well as on latest ATC information. PACE develops a cloud-based decision support tool where the resource demanding calculation of the aircraft performance as well as the optimization of the trajectory take place on a ground-based server while the EFB client application displays most efficient trajectories in real-time and enables pilot input.
