This manual, while focused on the FF-ICE concept, includes guidance material on the high-level process by which information is provided, the operational and technical environment within which the FF-ICE is expected to operate, and considerations for transition to the FF-ICE. As this concept is intended to support the vision articulated in the Global ATM Operational Concept, this manual is written with the expectation that the operational environment will be performance-based and will meet the eleven ATM community expectations defined in Appendix D of the Global Air Traffic Management Operational Concept (Doc 9854).
