At last someone who knows what they are talking about! Further: The A330 is NOT certified to autoland overweight, the FCOM says that it has been "demonstrated" and will given the balance of probalities and with no weather extremes will be OK. THe A330 also downgrades to Cat 111 Single when on one engine, because "Roll Out" is not certified in this condition. The A330 does however retain CAT111 Dual after a single generator failure because that APU Gen is certified with a power split.......
