Why do Boeing 737 crab during taxi? I've observe this on several occasions even in nil wind conditions!
I believe this is an aerodynamic equation in its design..thus while taxying it appears to be off wack. Once airborne the 737 is one helluva arrow! Good question !:ok:

I've always noticed this and wondered the same thing.
I ended up just putting it down to the fact that it ensures that the captain is always that one step ahead of the F/O :ok:

The main wheels have 2 - 3 degrees left/right play in them, so if the a/c lands in a cross wind the mains may be out at their limit. When taxying it then appears that the a/c is crabbing. The wheels are straight straight down the taxy way, but the fuselage looks (and is) a couple of degrees out of alignment.
