Standard Phraseology for Weather Deviation
Can anyone give me a reference for the ICAO standard phraseology for requesting a weather deviation? I looked through Doc 4444 and found a standard phrase used during CPDLC, but not for R/T.
While I think all 3 get the job done, I am curious if any are technically "standard":
"Request deviation X miles R of track due to weather" or
"Request deviation X miles R of track due to CB" or
"Request weather deviation X miles R of track"
