Part 1: Static Lateral Stability
The lateral motions in an aeroplane are of two types,assuming that the aeroplane posseses 'static stability' about the directional, or yaw axis ans has roll or 'dihedral stability'. Directional Stability addresses the tendency of the aeroplane to point into the oncoming airstream and is provided by the vertical fin.It is often referred to as "Dihedral Stability", since a wing dihedral angle provides the necessary restoring rolling moment.Dihedral (when wing tips higher than wing root..opposite to anhedral) effects on the rolling moment of a yawed wing.

As mentioned earlier other than spoileron "slaps" to bite off the otherwise divergent Dutch roll application of speed brakes was at how many units up?
