In Italy, I came across some runway reference like


I suppose the meaning of "d" is for "decollo" ("takeoff"). Is that desirable? Is this information not to be mapped, since not observable aviation data? Otherwise, how can I define it?

Runways change takeoff/landing direction based on the wind. Usually, there are some runways that have a letter after a number, meaning there are two parallel runways and one is Left and the other is Right (so you can find 18R/36L and 18L/36R) (see for example this query); there are also runways that are marked by a "C", which means they are the central runway among three. The D is not standard, so it should be either 18L/36R or, if it's the only runway, 18/36.

It looks like these "d" designations are also used in other documents when I searched the web. On the other hand they don't seem to be painted on the runway (e.g. Melendugno: aerial, OSM; Aliscarlino: aerial, OSM).

A lot of those runways have been mapped 11 years ago but there are also some more recent ones. Why don't you ask those mappers why they entered these designators? If they just copied unknowingly you might as well remove the ds.

Ok, I've just sent a message to the editor of the changeset where first "d" appeared.
