Air Traffic Flow Management Delay The duration between the last take-off time requested by the aircraft operator and the take-off slot given by the CFMU. It is expressed in minutes. (Eurocontrol CFMU)
Air Traffic Management As defined by the Special Committee on Future Air Navigation Systems (FANS), a system consisting of a ground part and an air part, both of which are needed to ensure the safe and efficient movement of aircraft during all phases of operation. The airborne part of ATM, according to FANS, consists of the functional capability which interacts with the ground part to attain the general objectives of ATM. The ground part of ATM comprises the functions of Air Traffic Services (ATS), Airspace Management (ASM) end Air Traffic Flow Management (ATFM). Air traffic services are the primary components of ATM.
Air Traffic Management (ATM) The ground part of ATM comprises the functions of aire services, airspace management and air traffic flow management. The air traffic services are the primary component of ATM.
Air Traffic Management Organisation An organisation that has the management of aircraft either in flight or on the manoeuvring area of an aerodrome vested in it and which is the legitimate holder of that responsibility.
