This edition of the Guidelines is in direct support to the EUROCONTROL Specification for On-Line Data Interchange Edition 6.0.
EUROCONTROL Guidelines for On-Line Data Interchange (OLDI)
These EUROCONTROL Guidelines provide clarifications, best practices and recommendations concerning the OLDI data exchanges for flights between air traffic control units by the use of electronic data transfer between flight data processing systems as well as the initial draft of future OLDI messages.
Background
Operational stakeholders identified a need for additional OLDI implementation material to help clarify the provisions contained in the OLDI specification. The need to produce the OLDI Guidelines was agreed within NM cooperative arrangements.
