Runway

A runway is a strip of land on an airport, on which aircraft can take off and land. Runways may be a prepared surface, (often asphalt or concrete) or an unprepared surface (grass, dirt, gravel).

Runway markings

There are various runway markings and signs on any given runway. Larger runways have a distance remaining sign (black box with white numbers). This sign uses a single number to indicate the thousands of feet remaining, so 7 will indicate 7,000 feet remaining.
