Last time I ran into chinese pilots at Boeing the trainer told me that they had interpreters as the chinese guys did not speak any english.
I know that russian pilots (who fly on B products in russia) study and subsequently perform all procedures in english because that's the way they were taught. Besides, isn't it the case that manuals for AC don't get translated to any other language just because english is the only language manuals were approved on? Since any translations may cause misunderstanding which can lead to some undesired events, B doesn't have other versions.
That was my understanding (misunderstanding perhaps).
But, from what is stated here I am not sure that my understanding is right. Could somebody clarify to me this issue?
