6.1 Safety notice
The 3D chart is an aid to visualization only. Always check your nor-
mal charts to ensure your route is safe.
Until you are familiar with interpreting the 3D chart display, take
every opportunity to compare what you see on-screen with your
actual surroundings. Practice harbour and coastal navigation dur-
ing daylight hours and in clear weather conditions.
You can use the 3D chart in simulator mode to help you gain
experience.
Before you use the 3D chart, read Chapter 4:Using Waypoints on
page 35 and Chapter 5:The Chart Application on page 43 for infor-
mation about reading chart information and using the G-Series
system navigation functions.
