In the aeronautical field, what does the color red typically signal?

In aviation, the color red is widely recognized as a signal for stop or danger. It is used in various contexts within the aeronautical field, such as markings on runways, obstacles in flight paths, and warning lights on aircraft. For instance, red lights may indicate a need for immediate attention or a prohibition against proceeding without taking further precautions. This safety convention is critical as it helps maintain safe operations in aviation, ensuring that pilots and crews are aware of potential hazards.

While other colors like yellow typically indicate caution or advisory warnings and green can often mean go or safe to proceed, red remains the unequivocal color denoting the need to stop and reassess the situation for any risks or dangers that may be present.
