Sivuväylävalot

Sivuväylävalot, also known as taxiway lights, are essential lighting systems at airports designed to guide aircraft along the taxiways. These lights ensure safe movement of aircraft on the ground, especially during periods of low visibility such as at night or in adverse weather conditions. They are crucial for maintaining air traffic control and preventing collisions.

There are typically two main types of sivuväylävalot: edge lights and center line lights. Edge lights are installed along the sides of the taxiway and are usually blue in color. They define the boundaries of the taxiway, indicating where the paved surface ends and the unpaved areas begin. This helps pilots stay within the designated path.

Center line lights are embedded in the surface of the taxiway and emit a continuous green light. Their primary function is to guide aircraft along the center of the taxiway, providing a clear path forward. In some cases, the green center line lights transition to yellow lights at holding points or intersections to indicate an upcoming change or caution.

The intensity and color of sivuväylävalot are standardized by aviation authorities like the International Civil Aviation Organization (ICAO) and the Federal Aviation Administration (FAA) to ensure consistency and safety across different airports worldwide. Proper functioning and maintenance of these lights are critical for the overall safety and efficiency of airport operations. Pilots rely heavily on these lights for navigation on the ground, especially in complex taxiway layouts or when visibility is reduced.
