Work Package 2 (WP2) aims at contributing to the Initial Trajectory Information Sharing (AF6 in CP1). It addresses the equipment onboard for the capability to downlink Extended Projected Profile (EPP) data via the automatic dependent surveillance - contract (ADS-C) from the aircraft, contributing to the SDM Family 6.1.1 “Initial A/G Trajectory Information Sharing (airborne)”.

The airborne implementation of ADS-C EPP functionality requires updating the Flight Management System and Communication Router to support EPP computation and downlink. EPP data accuracy can be improved by regular provision of improved flight and MET data to the flight crew ideally through digital means such as datalink.

Aegean Airlines, European Air Transport Leipzig, KLM, Lufthansa and its affiliate entities (Austrian Airlines, Brussels Airlines, EW DISCOVER GMBH, EUROWINGS GMBH, Eurowings Europe Limited and Lufthansa City Airlines GMBH), Scandinavian Airlines and Air France’s affiliated entity Transavia France, will upgrade Avionics implementing ADS-C EPP capability on existing fleets (retrofit) or order new aircraft with EPP capability (linefit), contributing to the SDP Family 6.1.1.

The specific objectives of this work package are the following:
- To equip existing fleet with ADS-C EPP capability by upgrading Flight Management System and Communication Routers (retrofit);
- To purchase ADS-C EPP avionics and equip with this functionality new aircraft acquired during the implementation of the project.

WP2 is linked to WPs 3 and 4 within this project, as all of them contribute to ATM Functionality 6 “Initial Trajectory Information Sharing"

Expected benefits of WP2

The partial deployment of “Family 6.1.1 Initial A/G Trajectory Information Sharing (airborne)” will contribute to the following performance benefits:
- Flight optimisation, with the optimisation of climb and descend profiles.
- Route optimisation, with the reduction of miles flown.
- Fuel consumption reduction, with the consequent reduction of CO2 emissions.
- Reduce the traffic regulations (delays) through a more optimized network.
- Reduce the tactical interventions.
- ADS-C EPP capability will improve automation and allow ATC to optimize flight paths.

The optimization of flight vertical profile contributes to the reduction of CO2 emissions and fuel consumption.
