captjns: Thanks, I re-read a previous post and better understand your point.
The system is basically designed for foggy (read still air) conditions. Never mind being way beyond the autoland system's capabilities (15kt crosswind, 25kt headwind), I find it amazing that any 737 pilot would even attempt an autoland in such weather.
If that is what some people do, it is testament to Boeing that there are not more crashes, and an even worse testament to some people's lack of faith in their own abilities as a pilot.
