Well, Alex, I have to admit that I understand the scepsis of mr. wing.
If you are really a 737 pilot, and cross rated on the different types (like myself), you would realise that the different types all have different crosswind restrictions for autoland.
You would also realise that the autopilots don`t give a toss what the weather looks like, outside
p.s. knowing the crosswind capabilities of the 737 autoland, I wouldn`t try it with 30 kts crosswind. Especially on the 3/400 it is not a good idea.
