4-7-7. WEATHER INFORMATION

EN ROUTE

When an available official weather report indicates weather conditions are below a 1,000-foot (USAF: 1,500-foot) ceiling or below the highest circling minimum, whichever is higher, or less than three-miles visibility for the airport concerned, transmit the weather report and changes classified as special weather observations to an arriving aircraft prior to or as part of the approach clearance when:

1. It is transmitted directly to the pilot via center controller-to-pilot communications.
2. It is relayed through a communications station other than an air carrier company radio or through a nonapproach control facility. You may do this by telling the station or nonapproach control facility to issue current weather.
