kiitotiet
Kiitotiet are essential components of airports, serving as the paved surfaces where aircraft take off and land. Their design and construction are crucial for the safe and efficient operation of air travel. The length and width of a kiitotie are determined by the types of aircraft it will accommodate, with larger commercial jets requiring longer and wider runways. Materials used in construction typically include asphalt or concrete, chosen for their durability and ability to withstand the immense forces exerted by aircraft. Kiitotiet are often equipped with lighting systems to guide aircraft during nighttime operations and in low-visibility conditions. These lights include runway edge lights, threshold lights, and end lights, each serving a specific navigational purpose. In addition to lighting, markings are painted on the kiitotie to indicate its center line, edges, and touchdown zones. These markings provide visual cues for pilots during landing and takeoff. The proper maintenance of kiitotiet is paramount, involving regular inspections and repairs to ensure a smooth and safe surface. Obstacle limitation surfaces are also established around kiitotiet to prevent any obstructions that could endanger aircraft.
