For TLOF PANS-AIM requires some basic properties as part of the minimum AIP data set. These are
designator, centre point, length, width, surface type
The diagram below shows the AIXM classes, including the relevant data types, needed to encode that information:
TLOF designator
TLOF Centre Point (aimingPoint)
TLOF Dimension (lenght & width)
Surface
The surface specification of a runway is related to the complete runway as a physical element and not related to the different runway directions.
The SurfaceCharacteristic class groups together the attributes that model characteristics of an airport surface, such as strength, material, etc.
For detailed information about the surface characteristic attributes & corresponding rules please refer to topic Surface Characteristic [SCH].
Coding Rules for Basic Data for Runway
Coding Examples
TBD in the scope of the DONLON AIXM AIP dat set.
