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.
