The vertical accel gain can often be left set at 1.00, but can be used to improve altitude captures when
climbing or descending in VS or VNAV mode.
1. Climb to an altitude target in VS mode and observe the altitude capture.
2. Set the vertical accel gain higher if the aircraft objectionably overshoots the altitude target before
leveling off at the correct altitude.
3. Set the vertical accel gain lower if the aircraft objectionably undershoots the altitude target before
leveling off at the correct altitude.
Similar to the vertical speed gain and vertical accel gain, the airspeed gain and airspeed accel gain can be
used to improve airspeed hold performance when needed.
The yaw servo has additional advanced and expert settings that can be adjusted to achieve the desired yaw
damping performance. These settings are detailed in
studying the description to properly understand their effect on the yaw servo. See preceding
the advanced/expert settings.
