Tag:aeroway=highway_strip

Landing strip that is normally used as a part of a highway, but can be closed either because of a military exercise or emergency landing for aeroplane landing. The tag should only be used when the strip has been designated as a landing strip. It is not intended for other possibly suitable landing strips.

A qualifying highway strip will usually be marked to aviation maps and have traffic signs before the strip warning of landing or low-flying aircraft. The paving is usually wider than needed for the highway and there are no traffic signs near the sides of the strip or they can be easily removed. The strip may or may not have center line, threshold or other runway-related markings.

How to map

Add the tag in addition to the highway=* tag for a way in the length of the highway strip. Tag the highway features as usual. If the highway strip has features that conflict with the highway (for example a distinct name), map the aeroway as separate way from the highway.

Tags to use in combination

• ref=* – the strip runway designator (for example "02/20" or "09L/27R"). List the smallest designator first (i.e. "04/22", not "22/04"). The two designators of a runway will always differ by 18 (180 degrees) and can have one letter appended (L, C or R). Only use other values in special cases.
• length=* – can be used to hold the physical length of the strip surface, including displaced threshold, etc. This is generally more than the length actually available for takeoff and landing. Use meters, or specify units. ('100' for a hundred meters, or '200 ft' for 200 feet.
• ele=* – should be used for the average elevation of the strip
• surface=* – to be used to identify the physical makeup of the surface of the runway. Example: "paved" or "grass".
• name=* – If the runway has a distinct name. Should not be a copy of ref. Examples: "Polderbaan" and "Aalsmeerbaan" at Amsterdam airport.
