One of the main obstacles of reaching Single European Sky’s objectives is management of flight trajectories. Inaccuracies are difficult to spot and information given to stakeholders about the trajectory is limited, arriving late, and full of inconsistencies and wrong assumptions. Military Flights are currently not integrated in the ATM-system, so demanding special treatment.Additionally, there is a lack of complete, updated, unique and coherent aeronautical and meteorological information at European level, which again limits the accuracy of the predicted trajectory and so difficult detecting incoming issues and designing optimum solutions.This project addresses solutions for the above limitations. Harmonized and global trajectory information sharing, including improved negotiation mechanisms, will enable significant operational benefits on flight management. The aim is to enable a unique and integrated view of all flights trajectories (including military ones) among the stakeholders. This is improved thanks to new tools and capabilities ensuring all stakeholders are managing a single, updated and complete view of the forecasted meteorology and airspace configuration.Both solutions above will increase safety and efficiency - a very important step towards ensuring that anyone can fly safer, cheaper and quicker in Europe in 10 years.As so many stakeholders are involved, this issue cannot be solved at national level. All stakeholders (mainly air navigation service providers, as well as air and ground industry partners) need to be involved as all will need to perform changes to ensure successful implementation. The SESAR 2020 Programme is the only place where this can happen.In this project we have ensured participation of the major ATM stakeholders which ensures having the knowledge and expertise to come up with the concepts, prototypes and platforms to provide sustainable results usable throughout Europe.
