SHARING TRAJECTORY DATA FOR IMPROVED FLIGHT EFFICIENCY

Today, when an aircraft leaves one national airspace and enters another, the adjacent centres exchange a basic or minimum set of flight information through an on-line data interchange mechanism known as OLDI. Centres further downstream however, do not get access to this information straight away and must rely on the originally filed flight plan in order to organise their airspace. To address this, SESAR is developing Europe’s first system for continuous exchange of flight information between all actors managing an aircraft at all stages of its journey.

The system-wide information management (SWIM) blue profile consists of a secure technical infrastructure that allows the implementation of interfaces between systems, providing technical capabilities for the secure, high-performance and reliable exchange of trajectory information between ATC centres via an IP network.

The solution supports the concept of the ‘flight object’, which is a single entity holding the most up-to-date information about a flight, allowing controllers to conduct silent coordination between adjacent units all along the flight. In this way, all air traffic control facilities along the flight hold a consistent view of the flight at all times, which supports seamless cross-border operations, including for example cross-border free route operations. This solution represents a key enabler to support any ATM solution that require an interface between different ground control centres when managing trajectories (e.g. Free route operations).

The trajectory information is used for the coordination of tasks and controller assistance services between different ground control centres.

Access to common trajectory flight data can result in more effective and better optimised coordination between adjacent ATC centres (or ANSPs)
