What is the problem/issue being addressed? : The proposal is part of the general principle of Trajectory Based Operations, aiming at equipping Air Traffic Control with enhanced features that allow to manage real time 4D trajectory data downlinked by the aircraft providing much larger time horizon about aircraft route intent and associated performances along it. PJ38 continues previous SESAR initiatives (PJ31 DIGITS, DIGITS-AU) and is the main contributor to prepare the industrial implementation as required by the Common Project #1.
Why is it important for society? : PJ38 ADSCENSIO contributes to cope with demand for air traffic growth and therefore airspace capacity increase. It aims as well for more optimised aircraft trajectory by allowing aircraft to fly their calculated trajectory essentially thanks to less air traffic control instruction. This can be obtained thanks to higher predictability and accuracy brought by the 4D information. As a consequence, there is a direct effect on possible gains of CO2 emissions reduction.
The overall objectives of ADSCENSIO are to demonstrate:
- the improvements that can be achieved in many common operational situations that Air Traffic Controllers have to manage, and
- the efficiency and robustness of a technological infrastructure to support the datalink communications between the aircraft and various ground consumers for trajectory related exchanges.
In details, the objectives of ADSCENSIO are:
- Continue the data collection of ADS-C reports and related data sent by airline’s aircraft equipped with the capacity to downlink flight trajectory information,
- Analyse characteristics, performance, and behaviour of ADS-C Data Contents from operational and technical perspectives,
- Perform operational evaluations to demonstrate and characterize the benefit of integrating ADS-C data in ATC systems,
- Demonstrate the feasibility of an efficient distributed ADS-C service (“ADS-C Common Service”) on the ground, and
- Demonstrate the use of SATCOM link to complement VDL2 technology to ensure Air-Ground ATN connectivity.
