Future ATFM Measures (FAM) Conceptual Basis
Today, in order not to deliver traffic over the capacity of control positions, the ATFM system delays aircraft on the ground. "Slots" are issued two hours before take-off time. Because of operational drifts (in between the slot issue time and the actual entry time of the aircraft in the congested area), very often, actual traffic situations are very different from ground delay system results.The FAM concept aims to propose and test a particular approach to complement the current ATFM system using traffic synchronisation: implementing actions on airborne aircraft (re-routing, sequencing) on close aerodromes ("minimal departure interval") or on airspace configurations. This is based upon a better accuracy of traffic prediction (ETFMS) and a dynamic negotiation between traffic managers (ANSPs and CFMU) co-involved in the implementation of these actions.
