Runway

Runways a children elements of an Airport. They don’t have any child element themselves.

Runways are assigned AIDs in the RWY namespace.

A Runway represents a landing surface in one of its usable directions, if applicable. For example, at an airport with one runway oriented North/South and usable in both directions, there will be two RWY elements, one representing the northbound take-off and landing direction and the other its southbound counterpart.

PropertyTypeDescription
aidstringA string with the AID of the airport, with RWY as namespace
identifierstring, nullThe runway identifier, for example 35L.

Can be null if helipad is true
