specified, at either of the following places:
(i) at the end of the last procedure turn, base turn or inbound turn of a racetrack
procedure, if specified;
(ii) at the point of the interception of the last track specified in the approach
procedure,
(b) ends at a point in the vicinity of an aerodrome from which a landing can be made or
a missed approach procedure is initiated;
(49) ‘flight documentation’ means documents, including charts or forms, containing
meteorological information for a flight;
(50) ‘flight information centre (FIC)’ means a unit established to provide flight information
service and alerting service;
(51) ‘flight information region (FIR)’ means an airspace of defined dimensions within which

or period, and for a specified area or portion of airspace;
(55) ‘forecast for take-off’ means a forecast for a specified period of time, prepared by an

the mathematical reference ellipsoid;
(58) ‘grid point data in digital form’ means 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;
(59) ‘guidance material’ means non-binding material developed by the competent authority that
helps to illustrate the meaning of a requirement or specification and is used to support the
interpretation of Regulation (EC) No 216/2008, its implementing rules and AMC;
(60) ‘gridded global forecasts’ means forecasts of expected values of meteorological elements
on a global grid with a defined vertical and horizontal resolution;

effect;
(62) ‘height’ means the vertical distance of a level, a point or an object considered as a point,
measured from a specified datum;
(62) (A) ‘heliport’ means an aerodrome or a defined area on a structure intended to be used
wholly or in part for the arrival, departure and surface movement of helicopters;
(62) (B) ‘identification’ means the situation which exists when the position indication of a
particular aircraft is seen on a situation display and positively identified;
(62) (C) ‘integrity classification’ means, in relation to aeronautical data, a classification based
upon the potential risk resulting from the use of corrupted data, defining routine, essential
and critical data;

only for dissemination at the aerodrome of origin where the observations were made;
(65) ‘local special report’ means a meteorological report issued in accordance with the criteria
established for special observations, intended only for dissemination at the aerodrome of
origin where the observations were made;
