That meant that, outside the flight envelope, simulators can't tell the BEA (for sure) that an imput is actually valid in relation with aircraft control surfaces position: as simulators are not supposed to derive anything accurately out of envelope's flight domain.
Hence, this part could only be verified by test flight (if one want to risk an A330 to verify that) which the BEA did not do up to this point (understandable).
