The order in which two or more aircraft are cleared to approach to land at the aerodrome.Ī defined area on an aerodrome, intended to accommodate aircraft for purposes of loading or unloading passengers, mail cargo, fuelling, parking or maintenance. The vertical distance of a level, a point, or an object considered as a point, measured from mean sea level.Ī unit established to provide air traffic control service to controlled flights arriving at, or departing from, one or more aerodromes.Īir traffic control service for arriving or departing controlled flights. Furthermore the horizontal separation is decomposed into the lateral and the longitudinal separations.Ī continuous volume of defined dimensions.Īn indication of an existing or pending situation during aerodrome operations, or an indication of abnormal A-SMGCS operation, that requires attention/action.Ī service provided to notify appropriate organisations regarding aircraft in need of search and rescue aid, and assist such organisations as required. Separations are defined in the vertical and the horizontal planes. Separation is the generic term used to describe action on the part of ATC in order to keep aircraft, operating in the same area, at such distances from each other that the risk of their colliding with each other is reduced. This term refer to the aggregate of organisations and people who own and/or operate the equipment, infrastructure, procedures, rules and information used to support their overall mission (to conduct flight operations).

The Special Committee on FANS described ATM as 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.Ī generic term meaning variously, flight information service, alerting service, air traffic advisory service, air traffic control service (area control service, approach control service, or aerodrome control service).

Information related to flight safety, air navigation, technical, administrative or legislative matters.Ī publication issued by or with the authority of a State and containing aeronautical information of a lasting character essential to air navigationĪll aircraft in flight or operating on the manoeuvring area of an aerodrome.Ī service provided within advisory airspace to ensure separation, in so far as possible, between aircraft which are operating on IFR flight plans.Ī service provided for the purpose of preventing collisions between aircraft and, on the manoeuvring area, between aircraft and obstructions, and expediting and maintaining an orderly flow of traffic. The minimum visibility at or above which the declared movement rate can be sustained by an A-SMGCS. The movement of an aircraft on the movement area. Advisories are of the following type: time, speed, direction, holding information.Ī defined area (including any buildings, installations, and equipment) intended to be used either wholly or in part for arrival, departure and surface movement of aircraft and operational vehicles.Īir traffic control service for aerodrome traffic.Ī unit established to provide air traffic control service to aerodrome traffic. Advanced Surface Movement Guidance and Control SystemĪ system providing routing, guidance, surveillance and control to aircraft and affected vehicles in order to maintain movement rate under all local weather conditions within the Aerodrome Visibility Operational level whilst maintaining the required level of safety.Ī message that serves to warn the controller of actual or anticipated actions that are required to bring a flight back to plan.
