Air Traffic Flow Management
Air Traffic flow management service is established to support ATC in ensuring an optimum flow of traffic to, from, through or within defined areas during times when demand exceeds, or is expected to exceed, the available capacity of the ATC system, including relevant aerodromes. ATFM should be developed as necessary to ensure this optimum flow.
Air Traffic Flow Management Airport Delay
Delay caused by regulation based on traffic volume which has a reference location classified as AZ (Aerodrome Zone) or AD (Aerodrome). (Eurocontrol CFMU)
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.
Air Traffic Management Service Top level generic description of Air Traffic Management Services delivered by the Air Traffic Management Service Provider. ATM includes Air Traffic Services, Airspace Management and Air Traffic Flow Management where the ATS is considered to be the primary component of ATM.
Air Traffic Service A generic term meaning: Flight Information Service, Alerting Service, Air Traffic Advisory Service, Air Traffic Control Service, Area Control Service, Approach Control Service or Aerodrome Control Service.
Air Traffic Service (ATS) A generic term meaning variously, flight information service, alerting service, air traffic advisory service, air traffic control service.
Air Traffic Service Airspace (Class A to G) Are airspaces of defined dimensions, alphabetically designated, within which specific types of flights may operate and for which Air Traffic Services and rules of operations are specified.
Air Traffic Service Direct Speech Circuit An aeronautical fixed service telephone circuit, for direct exchange of information between air traffic services units.
Air Traffic Service Environment Data Base is a specific part of the CFMU Data Base containing all environment data concerning airspace organisation and structure, ACC operational organisation and ATC capacities. The ATS Environment Data Base is used by the CFMU systems for the calculation of flight profiles taking account of all the airspace constraints.
