Kiitoradoille

Kiitoradoille is a Finnish term that translates to "runways" in English. It specifically refers to the prepared surfaces at airports and airfields used for aircraft takeoffs and landings. These surfaces are engineered to withstand the immense forces exerted by aircraft during these critical phases of flight.

The construction of a kiitorado involves several layers of materials, typically starting with a sub-base of compacted soil or gravel, followed by layers of crushed stone and asphalt or concrete. The specific materials and thickness of these layers are determined by factors such as the expected traffic load, climate, and soil conditions. The surface is also designed with a specific gradient to allow for drainage and to prevent water accumulation, which could be hazardous.

Kiitoradoille are meticulously maintained to ensure safety. This includes regular inspections for cracks, potholes, and other damage, as well as ensuring adequate lighting for nighttime operations and low-visibility conditions. Markings on the runway, such as centerlines, threshold markings, and touchdown zone indicators, provide visual cues for pilots. The length and width of a kiitorado are determined by the types of aircraft it is designed to accommodate, with larger and heavier aircraft requiring longer and wider runways. The term can also be used in a more general sense to refer to any long, straight path designed for rapid movement, though its primary association is with aviation.
