(1) On the STEERING GEAR CONTROL PANEL (FIGURE 2-149.2) set the "MODE SELECT
SWITCH" (3) "AUTO PILOT" position.
(2) On the STEERING GEAR AUTO PILOT CONTROL (FIGURE 2-149.6 adjust the "DIMMER
CONTROL" (7) for best reading level.
(3) Change course by adjusting the "HEADING CHANGER KNOB" (1) until the desired course appears
on the "BULB" (2).
(4) Set the "WEATHER KNOB" (5). A maximum setting (counterclockwise) is best for good sea
conditions and provides maximum course holding. The maximum setting (clockwise) is best for
rough
sea conditions.
(5) Set the "RUDDER MULTIPLIER KNOB" (4). This adjustment determines how much the heading
error signal is amplified before it is compared to the actual rudder position feedback signal.
(6) Set the "RUDDER LIMIT KNOB" (3). This adjustment limits the maximum rudder travel that may be
commanded by the auto pilot amplifier.
(7) Adjust the "HELM TOGGLE SWITCH" (6). The "PERMANENT HELM" adjustment allows the auto
pilot amplifier to bring the vessel to the exact desired heading in the presence of a steady wind or a
steady running sea, which would tend to push the vessel continuously off course. The.
"PERMANENT HELM TOGGLE SWITCH" (6) should remain in the "OFF" position during calm
winds and seas.
(8) As the craft comes to new heading, verify that the "BULB" (2) indicates new heading.
NOTE
During normal steering gear operation the port and starboard steering gear
ram lock valves will remain open at all times.
