The SCAS dampens response from outside factors like wind, but the Kiowa is a very nimble aircraft and very light...stable is not a word I would use to describe it.
The SCAS is a three-axis (pitch, roll and yaw) flight
control augmentation system with a heading hold mode
(HHM). This limited authority, rate reference system
improves handling qualities by damping the high frequency,
short term external inputs to the helicopter
while providing the desired response characteristics
for pilot inputs. The heading hold mode operates in
conjunction with the yaw SCAS system as an aid to
maintaining a desired heading.
