List of attributes

Name Data Type Definition  
category CodeCheckpointCategoryType Indicates the position of the checkpoint; airborne or ground  
upperLimit ValDistanceVerticalType Indicating the upper limit of the block in which the check should be conducted.  
upperLimitReference CodeVerticalReferenceType A code indicating the reference for a vertical distance. Two series of values exist: 1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid 2) pressure distance: QFE, QNH, STD.  
lowerLimit ValDistanceVerticalType Indicating the lower limit of the block in which the check should be conducted.  
lowerLimitReference CodeVerticalReferenceType A code indicating the reference for a vertical distance. Two series of values exist: 1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid 2) pressure distance: QFE, QNH, STD.  
altitudeInterpretation CodeAltitudeUseType Indicates how the upper and/or lower altitude values should be interpreted.  
distance ValDistanceType The value of the distance from the checkpoint to the navaid.  
angle ValBearingType The indication of a bearing (at a given point) by the measurement of the angle between the checkpoint and the navaid equipment (VOR)
