B744 Autoland in crosswind
The B744 localizer antenna is located in the radome with the weather radar so the whole aircraft is downwind of the centreline in a crosswind. The only way the autopilot can align the body gear with the runway centreline is to use the sideslip, wing low method. Boeing recommend the De-Crab during flare method for manual landings to maintain the wings level throughout the approach, flare and touchdown. This works well if you don't float...in which case you have to resort to the sideslip wing low method to maintain the centreline. Hopefully, Boeing will locate the localizer antenna near the body gear on the B747-400 Advanced.
