A major real-time simulation to validate procedures supporting Trajectory-Based Operations (#TBO) recently completed at #EIH the EUROCONTROL Innovation Hub 💡
Controllers from the Polish Air Navigation Services Agency 🇵🇱 and the Romanian Air Traffic Services Administration (ROMATSA) 🇷🇴 took part in this SESAR Joint Undertaking ATC-TBO exercise to assess:
✈️ datalink-enabled closed clearances,
✈️ ADS-C EPP reporting, and
✈️ ground automation tools that generate CPDLC advisories in the vertical dimension,
✈️ enabling the optimisation of climbs and descents.
The simulation included:
🔗 a live connection with an Airbus A321 simulator in Toulouse to validate cockpit workload & management of these clearances, and
🔗 a real-time connection to skyguide's SkyTICS system to validate ground–ground aspects.
It was shown that trajectory revisions for TBO can be coordinated using standard operational On-Line Data Interchange (OLDI) TBO between two ANSPs, sending a very strong message for short-term deployment.
The tested procedures deliver key benefits such as:
⭐ a significant reduction in controller workload,
⭐ the potential for major increases in en-route capacity, and
⭐ increased predictability thanks to air-ground trajectory synchronisation.
A big thank you to all partners, and to the EIH operational, validation, human-factors, safety and technical teams, for pushing the TBO concepts closer to operational use!
