Local Control must visually scan for aircraft on runways throughout the entire shift to ensure safety and effective operations. This continuous monitoring helps to maintain situational awareness and recognize potential conflicts or hazards, such as aircraft that may have inadvertently entered a runway or are on approach without clearance. It is a critical part of the controller's responsibilities to oversee all runway activity, thus minimizing the risk of runway incursions and ensuring that all operations proceed as planned. Constant vigilance helps controllers manage traffic flow and respond quickly to any changing situations that may arise during their watch without relying solely on communication from pilots or situational peaks. This proactive approach is essential in maintaining the overall safety of the air traffic control environment.
