I don't understand why it is not CLEAR? It is a safety related problem!! You can not expect everybody to understand french...but they have to understand english! From 2008 also the chinese pilots will be required to understand english. Obviosly they (Air China) also resist.
From what I understand, the A380 problem was also related to a (computer) language problems between the french and germans. I say this is a EU problem. Aviation manuals in scandinavia are in english.
