Hmm... anyone bother to read the document? They're running "version A.0.4.5" of the FADEC controller software.
In PC speak, that's an alpha version... No wonder there are stuffups! Microsoft can't even get it right after version 5. ha!
Jokes aside, 411: take off weight/mass is not about european or not, it's about the *physically* correct term. takeoff weight is a useless quantity, as, physically speaking, the weight depends on the gravitational field you're in at the moment. So what you really mean is mass.
