Runway 27 is a designated flight path used at airports for takeoffs and landings. The number "27" indicates the runway's magnetic heading, which is approximately 270 degrees west. This runway is typically aligned with prevailing winds to ensure safer and more efficient aircraft operations. Airports often have multiple runways, and Runway 27 may be paired with its opposite, Runway 09, which is used for flights heading in the opposite direction. Proper signage and lighting are essential for pilots to navigate safely, especially during low visibility conditions.
