Someone on another thread mentioned English as the ICAO language. Even without EASA intervention would this not mean that all ICAO states should use English in RT transmissions? I do remember a caveat, years ago - perhaps before JAR, which said local language could be used if it did not infringe on safety. Is that still the case? e.g. South America, even Russia and other E European countries, before ELA rating in a licence had not yet been introduced.
