Using the Banking Curve
When Align to Path or Look At is selected in the Alignment option option, the Banking menu becomes available. Banking uses the normals of the path to orient objects attached to it. Use the banking curve and settings to control the torsion effect of the object as it travels along the 3D path.

The Position on Path settings are the same as those in the 3D Path menu. See Positioning Objects on the Path.
Banking Curve
Adds twists and torsion to the normals of the 3D path. Use the options in the Tools drop-down to add, select, delete, or move keyframes on the Banking curve.
The horizontal axis represents the length of the path, and the vertical axis displays the orientation, expressed in degrees.
Normals Offset Angle field
Displays the angle of rotation of all normals, applied to the entire banking curve.
