The study was part of the yearly NCD 'ATFCM Studies' work programme, in support of and funded by CFMU.
It appears that the ATFM performance assessment grid currently used at strategic level fails to provide explanations of a number of observed results on the field. At the present stage, no clear conclusion shall be taken for granted. However, it has been demonstrated by the analysis and throughout interviews with FMPs that FMPs / FMDs have developed methods of using the ATFM regulation process to fulfill a number of new operational objectives, which are not currently taken into account when evaluating the ATFM performance.
