ComNav 1101 Autopilot6 - 11 BASIC OPERATIONS
3. If the display reads ‘FAST” in the bottom right corner, press and
hold the SPEED button until the display reads ‘SLOW”.
4. Monitor the Autopilot performance for a few minutes. It should
maintain a steady course within the limits of the yaw setting.
(Press the YAW button to enter the Steering Parameter menu so
you can see what these limits are. Use the ADJUSTMENT
KNOB to change the Yaw setting if desired).
If the Autopilot does not maintain a steady course and begins to
“ess” back and forth, reduce the rudder gain. (Press the
RUDDER
button to enter the Steering Parameter menu and turn
the ADJUSTMENT KNOB one click counter-clockwise to reduce
the rudder gain by one level).
Proceed to step 5 once the Autopilot maintains a steady
straight–line course within the yaw setting. This is often judged
best by observing the vessel’s wake.
5. Make a 40-degree course change. The vessel should settle
onto the new course with one overshoot of 5 degrees or less.
6. If you were uncomfortable with how fast the vessel turned
during the maneuver in Step 5, adjust your turn rate up or down
before making more course changes in PILOT mode. (Press the
TURN RATE button to enter the Steering parameter menu and
turn the ADJUSTMENT KNOB counter-clockwise to reduce the
turn rate, or clockwise to increase the turn rate. Refer to Table
5 for turn rate settings).
7. If the vessel stops turning before the new heading is reached
and then approaches it slowly,
either
a) Increase the rudder one level. (Press the RUDDER button to
enter the Steering Parameter menu and turn the ADJUSTMENT
KNOB one click clockwise to increase the rudder setting by one
level).
or
b) Decrease the counter rudder one level. (Press the COUNTER
RUDDER button once to enter the Steering Parameter menu and
turn the ADJUSTMENT KNOB one click counter-clockwise to
decrease the counter rudder setting by one level).
8. If the vessel overshoots the new heading, and then makes
several turns across the new heading before settling down, then
either
a) Decrease the rudder one level. (Press the RUDDER button once
