c) when set to a pressure of 1 013.2 hPa, may be used to indicate flight levels. Note 2.— The terms “height” and “altitude”, used in Note 1, indicate altimetric rather than geometric heights and altitudes. Forecast. A statement of expected meteorological conditions for a specified time or period, and for a specified area or portion of airspace. GAMET area forecast. An area forecast in abbreviated plain language for low-level flights for a flight information region or sub-area thereof, prepared by the meteorological office designated by the meteorological authority concerned and exchanged with meteorological offices in adjacent flight information regions, as agreed between the meteorological authorities concerned. 2007/70/II. szám Chapter 1 Annex 3 — Meteorological Service for International Air Navigation 1-3 25/11/04 Grid point data in digital form. Computer processed meteorological data for a set of regularly spaced points on a chart, for transmission from a meteorological computer to another computer in a code form suitable for automated use. Note.— In most cases such data are transmitted on medium or high speed telecommunications channels. Height. The vertical distance of a level, a point or an object considered as a point, measured from a specified datum. Human Factors principles. Principles which apply to aeronautical design, certification, training, operations and maintenance and which seek safe interface between the human and other system components by proper consideration to human performance. International airways volcano watch (IAVW). International arrangements for monitoring and providing warnings to aircraft of volcanic ash in the atmosphere. Note.— The IAVW is based on the cooperation of aviation and non-aviation operational units using information derived from observing sources and networks that are provided by States. The watch is coordinated by ICAO with the cooperation of other concerned international organizations. Level. A generic term relating to vertical position of an aircraft in flight and meaning variously height, altitude or flight level. Meteorological authority. The authority providing or arranging for the provision of meteorological service for international air navigation on behalf of a Contracting State. Meteorological bulletin. A text comprising meteorological information preceded by an appropriate heading. Meteorological information. Meteorological report, analysis, forecast, and any other statement relating to existing or expected meteorological conditions. Meteorological office. An office designated to provide meteorological service for international air navigation. Meteorological report. A statement of observed meteorological conditions related to a specified time and location. Meteorological satellite. An artificial Earth satellite making meteorological observations and transmitting these observations to Earth. Minimum sector altitude. The lowest altitude which may be used which will provide a minimum clearance of 300 m (1 000 ft) above all objects located in the area contained within a sector of a circle of 46 km (25 NM) radius centred on a radio aid to navigation. Observation (meteorological). The evaluation of one or more meteorological elements. Operational control. The exercise of authority over the initiation, continuation, diversion or termination of a flight in the interest of the safety of the aircraft and the regularity and efficiency of the flight. Operational flight plan. The operator’s plan for the safe conduct of the flight based on considerations of aeroplane performance, other operating limitations and relevant expected conditions on the route to be followed and at the aerodromes concerned. Operational planning. The planning of flight operations by an operator. Operator. A person, organization or enterprise engaged in or offering to engage in an aircraft operation. Pilot-in-command. The pilot designated by the operator, or in the case of general aviation, the owner, as being in command and charged with the safe conduct of a flight. Prevailing visibility. The visibility value, observed in accordance with the definition of “visibility”, which is reached or exceeded within at least half the horizon circle or within at least half of the surface of the aerodrome. These areas could comprise contiguous or non-contiguous sectors. Note.— This value may be assessed by human observation and/or instrumented systems. When instruments are installed, they are used to obtain the best estimate of the prevailing visibility. Prognostic chart. A forecast of a specified meteorological element(s) for a specified time or period and a specified surface or portion of airspace, depicted graphically on a chart. Quality assurance. All the planned and systematic activities implemented within the quality system, and demonstrated as needed, to provide adequate confidence that an entity will fulfil requirements for quality (ISO 9000:2000*). Quality control. The operational techniques and activities that are used to fulfil requirements for quality (ISO 9000:2000*). Quality management. All activities of the overall management function that determine the quality policy, objectives and responsibilities, and implementing them by means such as quality planning, quality control, quality assurance and quality improvement within the quality system (ISO 9000:2000*). * ISO Standard 9000:2000 — Quality Management Systems — Fundamentals and Vocabulary. 2007/70/II. szám Annex 3 — Meteorological Service for International Air Navigation Chapter 1 25/11/04 1-4 Quality system. The organizational structure, procedures, processes and resources needed to implement quality management (ISO 9000:2000*). Regional air navigation agreement. Agreement approved by the Council of ICAO normally on the advice of a regional air navigation meeting. Reporting point. A specified geographical location in relation to which the position of an aircraft can be reported. Rescue coordination centre. A unit responsible for promoting efficient organization of search and rescue services and for coordinating the conduct of search and rescue operations within a search and rescue region. Runway. A defined rectangular area on a land aerodrome prepared for the landing and take-off of aircraft. Runway visual range (RVR). The range over which the pilot of an aircraft on the centre line of a runway can see the runway surface markings or the lights delineating the runway or identifying its centre line. Search and rescue services unit. A generic term meaning, as the case may be, rescue coordination centre, rescue subcentre or alerting post. Service area (world area forecast system). A geographical area within which a world area forecast centre is responsible for issuing area forecasts to meteorological authorities and other users. SIGMET information. Information issued by a meteorological watch office concerning the occurrence or expected occurrence of specified en-route weather phenomena which may affect the safety of aircraft operations. Standard isobaric surface. An isobaric surface used on a worldwide basis for representing and analysing the conditions in the atmosphere. Threshold. The beginning of that portion of the runway usable for landing. Touchdown zone. The portion of a runway, beyond the threshold, where it is intended landing aeroplanes first contact the runway. Tropical cyclone. Generic term for a non-frontal synopticscale cyclone originating over tropical or sub-tropical waters with organized convection and definite cyclonic surface wind circulation. Tropical cyclone advisory centre (TCAC). A meteorological centre designated by regional air navigation agreement to provide advisory information to meteorological watch offices, world area forecast centres and international OPMET data banks regarding the position, forecast direction and speed of movement, central pressure and maximum surface wind of tropical cyclones.
