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 used to describe the physical area of the runway.
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.
Hence, the Runway.type attribute can take the value 'RWY' or 'FATO'.
Runway designator
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 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.
It is also possible to add a prefix to the designator, e.g. RWY-18/36.
The value for the designator is limited to 16 characters.
Open Question to RWY designator
Runway Dimension (lenght & width)
The runway dimension attributes are used to describe the physical dimension of a runway.
The Runway.nominalLength ist he declared longitudinal extent of the runway for operational (performance) calculations.
The Runway.nominalWidth is the declared transversal 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.
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].
