Table 1-21 -- Example RCR coding
As you can see, aviation routine weather report coding is complex, and there are
elements that have not been covered in this section. The Surface METAR Observations
User's Manual, COMOCNOPSINST 3141.2, and Surface Weather Observing, FAA
Order 7900.5B, should be consulted if you have any questions on entries or codes.
You must transmit weather information to pilots via radio. Table 1-22 lists examples of
weather report coding and the phraseology that you use when you broadcast weather
reports using standard FAA voice procedures. For a more extensive listing, refer to
Flight Services, FAA Order 7110.10.
