[ISO 19103, chapter 6.5.7.2] Helper type for restrictions on Angle Helper type for restrictions on Frequency Helper type for restrictions on GroundSpeed Helper type for restrictions on IndicatedAirspeed Helper type for restrictions on Length Helper type for restrictions on Mass Helper type for restrictions on Pressure Helper type for restrictions on TrueAirspeed Helper type for restrictions on Volume Helper type for restrictions on Weight Helper type for restrictions on WindSpeed The value of a speed. [AIXM 5.1] A vertical distance value. [AIXM 5.1] A code indicating the reference for a vertical distance. [AIXM 5.1] The distance measured from the surface of the Earth (equivalent to AGL - Above Ground Level). [AIXM 5.1] The distance measured from the WGS84 ellipsoid. [AIXM 5.1] A code indicating the direction of the zero bearing. This value indicates that the direction is relative to True North. This value indicates that the direction is relative to Magnetic North. The vertical distance of a level, a point or an object considered as a point, measured from mean sea level (MSL). [ICAO Doc 4444] Unit of measure The amount of rotation needed to bring one line or plane into coincidence with another, generally measured in radians or degrees. [ISO 19103, chapter 6.5.7.9] Unit of measure A data type used to represent direction in the coordinate reference system. [ISO 19107, chapter 6.3.12.1] The value of a bearing indication (at a given point) is measured as the angle between the bearing and either True North or Magnetic North. The angle is measured clockwise from 0 degrees up to and including 360 degrees. The value can also be a VOR radial. [AIXM 5.1] A code indicating the direction of the zero bearing. A type for returning the separation between two points. [ISO 19103, chapter 6.5.7.7] A surface of constant atmospheric pressure which is related to a specific pressure datum, 1 013.2 hectopascals (hPa), and is separated from other such surfaces by specific pressure intervals. [ICAO Doc 4444] Unit of measure The frequency value of a navigation system. [AIXM 5.1] Unit of measure The speed of an aircraft relative to the surface of the earth. [ICAO Doc 9426] Unit of measure The vertical distance of a level, a point or an object considered as a point, measured from a specified datum. [ICAO Doc 4444] Reference for the vertical measure Unit of measure The uncorrected reading on the airspeed indicator. [ICAO Doc 9426] Unit of measure The measure of distance as an integral, for example the length of curve, the perimeter of a polygon as the length of the boundary. [ISO 19103, chapter 6.5.7.6] Unit of measure The value of a mass. [AIXM 5.1] Unit of measure The value of a pressure. [AIXM 5.1] Unit of measure The value of a temperature. [AIXM 5.1] Unit of measure The speed of the aeroplane relative to undisturbed air. [ICAO Doc 9713] Unit of measure An expression of an aircraft's vertical rate of change. [FIXM] Unit of measure The measure of the physical space of any 3-D geometric object. [ISO 19103, chapter 6.5.7.15] Unit of measure The value of a weight. [AIXM 5.1] Unit of measure Direction from which the wind blows. [International Meteorological Vocabulary, WMO] The speed of wind. [FIXM] Unit of measure
