๐โ๏ธ As we all digest festive fare, a useful update on progress on Trajectory-Based Operations ( ) from our Innovation Hub!๐ก
Before the break, our colleagues completed a major real-time to validate procedures supporting alongside controllers from the Polish Air Navigation Services Agency ๐ต๐ฑ & the Romanian Air Traffic Services Administration ๐ท๐ด.
The SESAR Joint Undertaking ATC-TBO exercise assessed:
โ๏ธ datalink-enabled closed clearances
โ๏ธ ADS-C EPP reporting
โ๏ธ ground automation tools that generate advisories in the vertical dimension enabling climbs ๐ซ & descents ๐ฌ to be optimised.
The simulation included:
๐ a live connection with an Airbus A321 simulator in Toulouse ๐ซ๐ท to validate cockpit workload & management of these clearances
๐ a real-time connection to skyguide's SkyTICS system to validate groundโground aspects.
The simulation showed that trajectory revisions for can be coordinated using standard operational On-Line Data Interchange ( ) TBO between 2๏ธโฃ ANSPs.
And that sends a really strong ๐ช message regarding deployment in the short-term!
The tested procedures deliver big benefits such as:
โญ a significant reduction in controller workload
โญ the potential for major increases in en-route capacity
โญ increased predictability thanks to air-ground trajectory synchronisation.
A big thankyou to all partners, and to the operational, validation, human-factors, safety & technical teams, for pushing important TBO concepts closer to operational use.
