How might the braking action be communicated to pilots?

Braking action is communicated to pilots mainly through ATIS (Automatic Terminal Information Service) broadcasts. ATIS is a continuous broadcast of recorded aeronautical information in busier airports, providing pilots with essential data such as weather conditions, runway information, and the braking action on runways. When braking conditions vary due to factors such as rain, snow, or ice, this information is critical for pilots to make safe landing decisions. The ATIS system ensures that all incoming pilots receive updated and consistent information regarding runway conditions, including any advisories on braking performance.

Other methods, while potentially informative, are not standard for communicating the current braking action directly. For instance, verbal communication from ATC, while important for many types of information, is not typically used for detailed reports on braking action. Similarly, the NOTAM system may include general advisories but is not a reliable real-time communication channel specifically for braking conditions. Posted signs at the airport can provide general information but do not offer the dynamic updates needed for runway braking action. Therefore, ATIS remains the primary method by which pilots receive real-time updates on the conditions affecting runway braking action.
