I think its great....
just as long as bi-lingual approach plates don't lead to an accident, that is.
Think about all the unecessary regulations and paperwork that are imposed on us all...largely (but not entirely) at the insistence of the french. Maybe, just maybe this will help one country to see how ludicrous the stupidity of unecessary laws and regulations has become.
What's the betting that being french they just ignore the ruling anyway...that's how they cope with JAA/EASA things that they don't like.
