[Brian Paul Wiegand]

Just as the skid pad is a test of steady state behavior, the slalom is a test of transient behavior. Transient behavior is dependent on the initial location of the instantaneous center (IC) of rotation. When a turning motion is started the transient state begins and the initial IC is located at some distance from the CG. As turning continues the IC moves toward the CG; when the IC becomes coincident with the CG and stays there then the transient state has ended and the steady state begins. The initial IC location is dependent on the DIY (Dynamic Index in Yaw) which is determined as "K^2/(a x b)", where "K" is the yaw radius of gyration and "a" and "b" are the distances of the front and rear axles from the CG. It is desirable to keep the DIY as small as possible to minimize the duration and magnitude of the transient state.
