Runway Direction Light System

RunwayDirectionLightSystem is a specialization of the GroundLightSystem feature. The figure below shows the structure of this specialization.

The RunwayDirectionLightSystem specialization adds an association with a RunwayDirection that it isProvidedFor. This association also makes the general properties of the airport where the light system is situated available. From the RunwayDirectionLightSystem feature the corresponding AirportHeiport feature is navigable via the RunwayDirection and Runway features. Furthermore the specialization adds the position attribute that indicates which part of the runway the lighting system serves (e.g. touchdown zone 'TDZ', center line 'CL', etc.).
