WebA dynamic stability region can be identified within the gCoM position/velocity phase plane with the help of an optimization procedure that accounts for gravity, friction, CoP, 1 and ankle torque constraints [116].The static (BoS) and dynamic stability regions are shown in Fig. 5.2 A. Apparently, the dynamic stability region is much larger than the static one. WebMay 1, 2000 · Longitudinal static stability involves maneuvering (traditionally called "maneuvering stability" or "man-stab") and non-maneuvering (traditionally called "long-stab" or "long-stat") flight. Both arise from your airplane's pitch response to an angle of attack change, but they are assessed differently. Man-stab is your plane's response during ...
