- Air traffic controllers are responsible for reporting runway conditions to pilots if they observe or are informed of any unsafe conditions. This includes relaying information to the airport manager and issuing NOTAMs if conditions cannot be confirmed. - Controllers must provide factual information on runway conditions such as snow or ice accumulation as reported by airport management. This includes braking action reports from pilots categorized as good, fair, poor or nil. - When braking action of poor or nil is reported or weather could impact conditions, controllers declare braking action advisories and provide updated reports to pilots.
