The FF-ICE concept is detailed below:
PRINCIPLESThe FF-ICE is guided by the requirement to eliminate or reduce the limitations of the present Flight Plan and to accommodate the future environment detailed in the Global Air Traffic Management Operational Concept (Doc 9854). The principles of the FF-ICE can be summarized as follows:
Regional variation required for performance reasons will be implemented by using different subsets of the standard information elements. New elements will be introduced regionally, through regional extensions as needed, but will not be mandatory for other regions, will not provide duplicate information of existing elements, and should be intended to become part of the global standard. A formal process will be introduced for migrating successful new elements into the standard information.
