Optimised airspace users operations

Helping to improve flight planning and prioritisation processes.

The SESAR 2020 optimised airspace user operations project (PJ07 - OAUO) is an industrial research and validation project, led by EUROCONTROL, that focuses on improving flight planning and prioritisation processes.

PJ07 addresses both civil and military airspace users, further improving their processes and tools, particularly in relation to their interaction with ATM Network Operations. At the core of these advances is an improved collaborative decision‑making (CDM) process that takes into account the evolving business needs of airspace users.


Most of the benefits of PJ07 are related to improved efficiency, flexibility and cost-effectiveness for the airspace users, which will be translated into potentially substantial cost savings.

According to the cost-benefit analysis carried out by the SESAR Joint Undertaking, this will result in potential savings of several hundreds of millions of euros over the next 20 years.


PJ07 was the first SESAR 2020 project to be launched, on 1 October 2016.

In the first wave of SESAR 2020, which will run until the end of 2019, the project will bring the different concepts to a higher level of maturity, following the definition and execution of several validation exercises.

As from 2019, trials will address collaborative decision‑making. Shadow-mode trials will also be organised to prepare for the industrialisation and deployment of the project.


SESAR 2020 introduces new concepts and brings the solution to a higher level of maturity through the development of requirements and validation exercises. PJ07 is structured along three solutions started in SESAR 1.  These solutions are:

Solution one - Airspace user processes for trajectory definition

Solution one will develop requirements and validate procedures and workflows for flight operations centres, enabling them to interact better with other ATM stakeholders, especially with the Network Manager, with regard to (medium and short term) trajectory definition. This will also ensure continuity in the CDM process throughout the trajectory lifecycle.

Solution two - Airspace user fleet priorities and preferences processes (UDPP)

Solution two is designed to smoothly integrate the priorities and preferences of airspace users via collaborative processes at airports and in network demand capacity balancing (DCB) processes, allowing those processes to perform multi-criteria optimisation tasks involving many stakeholders. This solution will also address how user fleet priorities and preferences processes can be used by airspace users that are not regular users at a given airport.

Solution three - Mission trajectory-driven processes

Solution three has the same major objective as the first solution, but is aimed at wing operations centres, and will focus in its first phase on harmonising military flight plans and integrating military traffic intentions into the overall European ATM network.
