The PARTAKE project enhances air space user’s trajectory preferences relying on robust Trajectory Based Operation (TBO) mechanism by relaxing tight interdependencies between trajectories. The underlying philosophy is to capitalize present freedom degrees between layered Air Traffic Management (ATM) planning tools, when sequencing departures at airports by considering the benefits of small departures time changes by Air Traffic Controllers (ATCos) at tactical phase.

In 2010, the European Air Traffic Management System (ATM) faced 9.5 million flights (33.000 in peak days). Predictions state that 17 million flights (50.000 in peak days) will be reached out in 2030.

The current management system will not be able to deal with the above-mentioned huge increase in an efficient and safety way. This the reason why SESAR R&D programme was built, with the goal to tackle the coming air traffic management challenges, on the basis of innovative procedures and technologies, which will increase its efficiency under new growing demand scenarios.

In harmony with this approach, PARTAKE project –funded by SESAR as Exploratory Research one- aims to improve the aircrafts flow efficiency into the European air space, minimizing the current conflicts –we mean that two or more airplanes could temporarily match in a precise point because their initially scheduled departure time was modified by any circumstance- which are caused by airports local perspective. Particularly, these time-space dependencies are the main air space capacity limiters that PARTAKE solves, giving to the airports connected by the ATM system a global vision.

Nowadays, it should be noted that, despite the huge amount of real time existing data about airports, aircrafts, air space sectors –and its estimated evolution-, there are no tools for analyzing time-space interdependencies between such actors.

PARTAKE will implement a helping decision support system to prioritize the departure of those airplanes with the appropriated permit and whose turnaround has been already finalized, considering not only airport information (taxiways and runways status) but also the trajectory air side impact. In this manner, air controllers usual route modifications that guarantee safety flights will be minimized. PARTAKE’s starting point is the time-space analysis of the flight plans requested by the airlines with the view of identifying those air space areas where demand is higher than capacity and, consequently, departures will be adapted to expand the separation between aircrafts in congested traffic aeras.

An available tool to coordinate airplanes departure between airports to avoid air side conflicts will result in airlines and airports economic benefits, will improve passenger punctuality and will prevent unnecessary emissions generated by fuel consumption when conflict avoidance maneuvers will decrease.
