Auto Trim Motor Speed
The GSA 28 yaw damper has the ability to drive the auxiliary rudder trim
motor at various speeds.
The Auto Trim Motor Speed should be set so the auxiliary trim motor will
move as slowly as possible. The slowest possible movement will ensure
that there is no noticeable aircraft response when the auxiliary trim motor is
run during auto-trim.
The Auto Trim Motor Speed can be adjusted in percent from 5 to 100 in
steps of 5.
Ball Centering Gain
(advanced setting)
The GSA 28 yaw damper is capable of zeroing the aircraft’s lateral
acceleration or centering the ball as well as dampening aircraft yaw rates.
Ball Centering Gain is an advanced level setting and should only be
changed by the installer if the yaw damper is not properly zeroing the
aircraft’s lateral acceleration.
Increasing the Ball Centering Gain will cause the yaw damper to more
aggressively respond to non-zero lateral acceleration. Decreasing the Ball
Centering Gain will cause the yaw damper to respond less aggressively to
non-zero lateral acceleration.
Rate Filter Constant
(expert setting)
The GSA 28 yaw damper is capable of damping out yaw body rates to
keep the aircraft from shaking its tail. The Rate Filter Constant is used to
filter the aircraft yaw body rate.
Rate Filter Constant is an expert level setting, and should generally be not
be changed by the installer, the default value is 0.08.
Accel Filter Constant
(expert setting)
The GSA 28 yaw damper is capable of zeroing the lateral acceleration of
the aircraft. The Accel Filter Constant is used to filter the aircraft lateral
acceleration.
Accel Filter Constant is an expert level setting, and should generally be not
be changed by the installer, the default value is 0.16.
