CAUTION
Risk of unstable/unreliable heading in polar waters
When operating the vessel in polar waters, the heading information of
the gyrocompass may become unstable/unreliable resulting in possible
deviation. For safe steering in polar waters, the heading information of
the gyrocompass may therefore NOT be used for navigation and heading
information of a GNSS (Global Navigation Satellite System) compass be
preferred instead.
