ST80 Autopilot Keypad Operation Manual 9
2.6 Important Safety Information
The following rules should ALWAYS be observed when passage
making under autopilot control:
Maintain a permanent watch and regularly check all around for
other vessels and obstacles – no matter how clear the sea may
appear to be, dangerous situations can develop in minutes.
Maintain an accurate log of your vessels position by visual
bearings or radio/satellite position fixes.
Maintain a continuous plot of your position on a current chart.
Make sure that the autopilot heading will steer you clear of
obstacles. Always allow for tidal set – the autopilot cannot!
Even when your autopilot is locked onto a given track using a
radio/satellite navigation receiver, always maintain a log and
regular position plot – navigational signals can produce
significant errors in certain circumstances, errors which the
autopilot cannot detect.
Ensure that your crew is familiar with the procedures for
engaging and disengaging the autopilot.
When there is restricted sea room, make sure that a crew
member is stationed close to the autopilot keypad.
On power vessels, always maintain a permanent watch at the
steering station when the autopilot is engaged.
