Booster Longitudinal Dampers Module Settings and Functional Checks. February 19, 2014 Craig Drennan Introduction This is a working document, meaning that not only is it in perpetual DRAFT state waiting for input from others, but will be added to as time permits. This document contains three sections. The first simply list references discussing why and how the Booster Longitudinal Dampers operate and some history on what has been tried in the past and why the damping methods have changed.
