1.2 General operation of the
Gyropilot Graphic
The
Gyropilot Graphic
display is designed to control your pilot and your system. The
performance of the
Gyropilot
is excellent at any sailing speed. It will assist the helmsman
effectively, but must not be used as the primary means to navigate.
When the helmsman activates the pilot, the
Gyropilot 2 computer
stores the current value of
the channel concerned:
magnetic heading
,
wind
angle
or GPS course. This value becomes
the
reference point
.
Then, the
computer
integrates the data transmitted by the sensors and performs rudder
corrections according to two criteria:
- the cross-track error compared to the reference point, which is provided by the
fluxgate
compass (
compass mode
) or by the
masthead unit
(
wind mode
).
- the speed of rotation of the boat, which is provided by the gyro sensor. This rotation is caused
by the action of the rudder, the wind or the waves.
Hence the correction value is proportional to:
the cross-track error measured,
the gain value,
and inversely proportional to the speed of the boat.
CAUTION:
Never leave the helm without supervision. The helmsman must remain watchful and
attentive to the sudden events that can occur while the autopilot is operating. He must be
ready to retake control of the rudder at any moment.
