Runway Designation refers to the numerical code assigned to a runway at an airport, indicating its orientation in relation to magnetic north. Each runway is identified by a two-digit number, which represents the compass heading rounded to the nearest ten degrees. For example, a runway aligned with 90 degrees is designated as Runway 09. Runway designations are crucial for pilots and air traffic controllers, as they provide essential information for takeoff and landing procedures. Additionally, runways may have suffixes like "L" for left or "R" for right when parallel runways exist, ensuring clear communication and safety in air traffic operations.
