Runway 09 is a designated runway at an airport, oriented approximately 90 degrees from magnetic north. It is typically used for takeoffs and landings when wind conditions favor this direction, allowing aircraft to take advantage of headwinds for safer operations. Airports often have multiple runways, each numbered based on their compass heading. The number "09" indicates that the runway is aligned at 90 degrees, while the opposite runway, Runway 27, would be aligned at 270 degrees. Proper use of runways is crucial for maintaining safety and efficiency in air traffic management.
