Landningsbanan

Landningsbanan, or runway in English, is a rectangular area on an airfield prepared for aircraft to take off and land. It is typically made of asphalt, concrete, or a combination of both, and is designed to withstand the weight and stresses of aircraft operations. Landningsbanor are usually marked with a series of white lines and numbers to guide pilots. The numbers indicate the magnetic heading of the runway, divided by ten. For example, a runway marked with '27' is oriented approximately 270 degrees west.

The length and width of a landningsbana vary depending on the types of aircraft that will use it. Larger aircraft require longer and wider runways to safely land and take off. The surface of the landningsbana must be smooth and free of obstructions. Lighting systems are installed along the sides and at the ends of the landningsbana to facilitate operations during periods of low visibility or at night. These lights, known as runway lights, include threshold lights, edge lights, and approach lights, all designed to provide visual cues to pilots.

In addition to the paved surface, landningsbanor are surrounded by safety areas, known as runway safety areas or clearways. These areas are kept free of obstacles to minimize the risk of damage to aircraft that may overrun the runway. The design and maintenance of landningsbanor are crucial for the safe and efficient operation of air traffic.
