Navigating with Autopilot
If an Autopilot computer is connected to the system, Autopilot functionality will be included
in the Zeus Touch.
When you start navigation on a system with Autopilot functionality, you will be prompted to
set the Autopilot to navigation mode.
If you choose not to engage the Autopilot, the Autopilot can later on still be set to navigation
mode from the Autopilot menu.
For more information about Autopilot functionality see “Navigating with Autopilot” on page
27.

Navigation method
Different methods are available for calculating the distance and bearing between any two
points on a chart.
The great-circle route is the shortest path between two points. However, if you are to travel
along such a route, it would be difficult to steer manually as the heading would constantly be
changing (except in the case of due north, south, or along the equator).
Rhumb lines are tracks of constant bearing. It is possible to travel between two locations
using Rhumb line computation, but the distance would usually be greater than if Great circle
is used.
Steering alarm limits
Arrival radius
Sets an invisible circle around the destination waypoint.
The vessel is considered arrived at the waypoint when it is within this
radius.
Off course (XTE) limit
This parameter defines the vessel’s accepted offset distance from the leg.
If the vessel goes beyond this limit an alarm will be activated.
Arrival alarm
When the arrival alarm is enabled, an alarm will be activated when the
vessel reaches the waypoint or when it is within the specified arrival
radius.
