Category Setting Description
Navigation Setup Navigation
Gain
Allows you to adjust how
aggressively the autopilot
eliminates cross-track error
while following a Route-To
pattern.
If this value is too high, the
autopilot can oscillate back
and forth across the course
line over long distances.
If this value is too low, the
autopilot may respond slowly
in eliminating cross-track
error.
Navigation Setup Navigation
Trim Gain
Allows you to adjust the
acceptable amount of long
term cross-track error while
following a Route-To pattern.
Only adjust this setting after
the navigation gain has been
set.
If this value is too
high, the autopilot will
overcompensate for cross-
track error.
If this value is too low, the
autopilot will allow a large
long term cross-track error.
NOTE: Advanced configuration settings are available when using
the advanced configuration procedure ( page 13 ). Other settings are
available during normal operation of the GHP 20. See the configuration
section of the GHC 10 Owner’s Manual for more information.
