a bunch of guys asking if I had a copy of any documents with standard RT phraseology
CAP 413 Would be a good start.
CAP 413: Radiotelephony Manual | Publications | CAA
Dont agree with just English. If you are in France, why don't speak in French? Why English? For safety reasons? If both, flightcrew and atc are happy with any ICAO lang, just go ahead. Always following company procedures of course.
And what about aircraft transiting the airspace; German, English, Spanish, American, Italian, along with Far Eastern carriers and Middle Eastern carriers, Hungarian, Romanian, Polish, Swedish, Norwegian, Dutch.... etc. etc. ?
