braking action advisories

When tower controllers have received runway braking action reports that include the terms poor or nil, or whenever weather conditions are conducive to deteriorating or rapidly changing runway braking conditions, the tower will include on the ATIS (automated terminal information service) broadcast the statement, “Braking action advisories are in effect.” During the time braking action advisories are in effect, ATC (air traffic control) will issue the latest braking action report for the runway in use to each arriving and departing aircraft. Pilots should be prepared for deteriorating braking conditions and should request current runway condition information if not volunteered by controllers. Pilots should also be prepared to provide a descriptive runway condition report to controllers after landing. See also braking action report.
