Work Package 1

flight plan & trajectory

Our Challenge
This work package puts tatical flight profile optimization, operational efficiency and EFB application into focus. Enabling pilots to make informed decisions depends on the availability of on-board technologies such as EFB systems and aircraft connectivity (acccess to avionics data) as well as IP connectivity.
Our Vision and Mission

Flight profile optimization is very important. It helps airlines save fuel, money as well as CO2 emissions. Moreover, on-time performance and flight safety (turbulence avoidance) can be improved.

Considering unforeseen changes along the route (changing weather, ATC constraints) Pacelab Flight Profile Optimizer (FPO) provides cost optimal vertical trajectories for the remaining flight. In addition, interfacing with DLR’s Conflict Detection System helps propose conflict-free trajectories.

The Operational Flight Plan (OFP) is calculated by dispatch well in advance of the flight based on then weather forecasts and ATC information. Later deviations like last minute changes, extra fuel decisions, changed winds en route or new ATC constraints cannot be taken into account. During the flight FPO continuously re-optimizes altitude and speed to minimize total cost based on latest weather updates, actual avionics parameters, ATC constraints and pilot inputs.

our use cases and Cooperation

In work package 1, PACE will work with Jeppesen, Lufthansa (DLH) as an associated partner and DLR to take flight planning technology to a new level. Working closely with DLH, Jeppesen will identify the needs of today’s operational environment for improved, efficient flight profile planning and the use cases and scenarios for subsequent validation in work package 1. PACE will provide a vertical trajectory, calculated by FPO Cloud, which considers the latest weather and aircraft conditions and is optimal in terms of flight comfort, scheduled times and costs. The Conflict Detection System from DLR checks this trajectory for potential collisions with other flights trajectories, before the activation to the new trajectory is requested at ATC.

More detailed the focus lies on:

Match the profiles calculated by the Jeppesen systems with PACE’s fuel efficiency and emissions optimization capabilities. For this purpose, Jeppesen provides a briefing package (OFP) with JetPlanner Pro

Technical integration of Jeppesen flight planning systems and on-board information display systems with partner systems.

Provision of a new infrastructure to maintain the integration of the aircraft after take-off until landing and distribution of computing power between the on-board and ground.

With the support of the TU Darmstadt: Definition of use cases including pre- and postflight tasks from the perspective of an integrated mission management system to support the pilot in all phases of the flight. The interactions include the presentation of information on the input parameters of the optimization such as weather, maintenance events and crew management as well as the selection of intended trajectories and crew schedule scenarios.
