Always amazed to see how the language issue is alawys coming back here to the French , and CDG as if it was the only country and only airport in the world using dual language.
This acident is not a language issue. Actually you could turn this argument around, if English had been mandated for all aircrfaft in CDG that day , the QNH passed to the AF would most likely been 1011 as well., so in fact decreasing significantly the overall saftey by increasing the risk to other aircraft. .
I always was and still am all for a single global language in the R/T , but I also know that there is absolutely zero chance of having this pass any ICAO meeting., even more today than in 1944 with nationalsim on the rise everywhere. Language is cultural and part of a State Sovereingty and a change is never going to happen , Same as having the US adopting the metric system ( which is the international ICAO standard btw) . So we all have learned to live with these and mitigate the shortcomings.
