The giant numbers painted on the airport runways stand for the airport's name and are called a heading. The runway heading consists of two numbers between 1 and 36. This means the heading is based on the compass directions with 360 representing north, 90 – east, 180 – south, and 270 – west.
A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities. They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass.Taxiways can be a combination of letters and numbers, or letters alone. They are indicated on a black sign with yellow letters or a yellow sign with black letters and arrows. A black square with yellow letters and/or numbers inside signifies the plane's position on the various taxiways.
