Doesnt include speed, though I guess with a little algebra you could figure out with the distance vs time equation. spd=dist/time
edit: there is a physics equation that you can do to determine AOB, but it's at home, and its been a few years since I've used any physics. Although, if you have the manual to Silent Hunter 1, there are a couple of equations you can use. Maybe there is an online manual of SH1 'round these here parts.
