EASA aviation regulation details wind shear warning message templates for aerodromes. Mandatory elements include location, message type, time, and phenomenon identification (approach/climb-out). Warnings specify observed, reported, or forecast wind shear, potentially including surface wind details, altitude, and runway information. Cancellation procedures are also defined.
