Turbulance Tuning Procedure
Overview
Once you have configured your autopilot to capture and hold airspeeds and altitudes, you may wish to
adjust the ride quality in turbulence, particularly on the glideslope.
In general, the autopilot will attempt to maintain a constant G-loading through bumps by pulling or
pushing G to oppose G generated by "air pockets". The amount of G the autopilot will apply is limited by
G ERROR LIMIT. If, for example, you encounter a 0.5 G updraft, and G ERROR LIMIT is set to 0.25, the
most the AP can do to attenuate the bump is reduce it by 0.25 G.
The amount the autopilot will apply up to that limit is determined by G ERROR GAIN. If this is set to 1, for
every 1/10 G the airplane is bumped, the AP will apply 1/10 of a G. Increasing G ERROR GAIN will make
response more rapid, but also more abrupt, so use this setting with care.
