Airport Terminal & Runway
A runway is the area where an aircraft lands or takes off. It can be grass, or dacked dirt, or a hard surface such as asphalt or concrete. Runways have special markings on them to help a pilot in the air to tell that it is a runway (and not a road) and to help them when they are landing or taking off.
most airports, runways are constructed of man-made material, usually asphalt, concrete or a combination of both. … Pavement thickness varies from airport to airport, with commercial airports serving heavy aircraft having runway surfaces with a thickness between 10 inches and 4 ft., including the sub-grade.
Most planes use a long runway before takeoff to gain enough speed for the plane to lift up into the air. … They use thrust to take off and therefore need very little runway. The runway is important for most airplanes because it gives them enough time to accelerate to the required speed to lift into the air.
