Pilot Does Not Steer in a Straight Line
Fault Description
The Pilot seems unable to steer straight, it continually overcorrects course errors;
the wake has an "S" like appearance as the boat first steers several degrees off
course to port followed by several degrees off course to starboard.
Remedial Action
1)
Drive unit: check for any slack or backlash in the drive system, see earlier
section. For steering systems using hydraulics ensure that there is no air in
the system.
2)
Rudder reference sensor: check for any slack or backlash in the assembly
and associated linkages, see earlier section.
3)
Boat speed: check that the boat speed is operating correctly, if you are
using a manual boat speed ensure that it is realistic - low boat speed values
use more rudder movement.
4)
Settings: read the commissioning section of the manual carefully and
check that the settings in use are appropriate for the type of boat.
5)
Rudder gain: make large course changes using the pilot, if the gain value is
correct the rate of turn should be between 6 and 8 degrees per second.
Adjust if necessary, see page 60
6)
Boat lag: a boat lag value that is too small for the boat can cause instability,
try increasing the value slightly, see page 60
