For Runway, PANS-AIM requires some basic properties as part of the minimum AIP data set. These are
designator, nominal length, nominal width, surface type, strength.
The diagram below shows the AIXM classes, including the relevant data types, needed to encode that information:
...
The Runway class is basically used to give the runway a designator and to describe its dimension and surface. Additionally, information regarding the runway strip may be provided.
All other runway facets are described with respect to a RunwayDirection, for example stopways and protection areas; runway direction obstacles; approach lighting; declared distances and runway lighting.
Runway type
In AIXM, the Runway class is used to code the runway for airplanes but also to code the Final Approach and Take-off Area (FATO) for helicopters.
...
The Runway.designator attribute is used to code the full textual designator of the runway, used to uniquely identify it at an aerodrome/heliport. E.g. 09/27, 02R/20L, RWY 18.
The The attribute value should reflect the local convention for physical runway naming at the Airport. In particular, it is not necessary to concatenate the runway direction designator to form the physical runway designator, but this is not prohibited.
...
Like for Runways also a prefix can be given, e.g. 'FATO-03/21'.
Runway Dimension (
...
length & width)
The runway dimension attributes are used to describe the physical dimension of a runway.
The Runway.nominalLength ist he is the declared longitudinal extent of the runway for operational (performance) calculations.
...
For both attributes a dedicated attribute to provide accuracy information is available, lengthAccuracy and widthAccuracy.
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.
For the runway, PANS-AIM requires to provide the surface type and its strength defined by a Pavement Classification Number (PCN).
In AIXM 5, the SurfaceCharacteristicSurfaceCharacteristics.composition attribute is used to code the surface type, e.g. asphalt, concrete, grass, etc.
For coding the PCN, a set of attributes is provided by the SurfaceCharacteristic SurfaceCharacteristics class.
The SurfaceCharacteristic SurfaceCharacteristics class groups together more attributes to model the characteristics of an airport surface, such as preperation, surface condition, LCN, SWIL AUW, etc.
For detailed information about the ncoding encoding of the PCN and other the surface characteristic attributes & corresponding rules, please refer to topic Surface Characteristics [SCH].
