Out of curiosity, are the latest generation of aircraft (A350, B787, CS300/100) authorised to conduct an autoland with braking action less than good or on contaminated runways, or with turbulance greater than moderate? Just curious as current/previous generation aircraft (A320/A330/B737) are not allowed to conduct autoland ops in these conditions so just wondering if today's modern technology allows this type of landing, or if that's still another generation away?
