Can autoland systems of big Boeing/Airbus jets perform crabbing, de-crabbing and side-slip manuevers as responsively as a pilot would?
737 cat3a doesn't de-crab at all, it just touches down with the offset, and lets the main gear correct the drift. 737 main gear is built with the ability to castor a few degrees either way - which can be obvious if you are taxiing behind one in a crosswind (as it taxies somewhat "sideways"
)
Given some of the pilots I have flown with, YES - the system performs as well as a pilot!
