At EUROCONTROL, we are working to define and validate enhanced air and ground (A/G) operational procedures for trajectory-based operations (TBO) using controller-pilot datalink communications (CPDLC) clearances.
Such procedures can be used to:
- perform immediate changes (for both lateral and vertical dimensions), or
- anticipate and propose changes in advance, supported by datalink standards (ATN B1 and B2) and increased automation and use of ADS-C EPP information.
EUROCONTROL is leading the initiative, supported by 56 partners from across the industry, including air navigation service provides (ANSPs), airspace users (AUs) and industry representatives, to define and validate the operational and technical requirements supporting the improvement of the complex clearances to ensure the synchronisation of air and ground trajectories.
