Landningsbana

Landningsbana is the Swedish word for runway. A runway is a defined rectangular area on an airfield prepared for the landing and takeoff of aircraft. Runways are typically constructed from asphalt or concrete, though some may be made of gravel or compacted earth. The surface must be smooth and level to ensure safe operations.

Runways are distinguished by their orientation, which is determined by prevailing wind conditions. Aircraft take off and land into the wind to maximize lift and minimize ground speed. The length of a runway is determined by the performance requirements of the aircraft that will use it, with larger, heavier aircraft requiring longer runways.

Runways are marked with numbers and lines to guide pilots. The numbers indicate the magnetic heading of the runway, rounded to the nearest ten degrees. For example, a runway designated "27" is oriented approximately 270 degrees magnetic. Lines on the runway provide visual cues for alignment and touchdown.

Modern runways often feature lighting systems to facilitate operations during periods of low visibility or at night. These lights include runway edge lights, threshold lights, and approach lights. The design and maintenance of runways are critical components of aviation safety.
