7.9 Sea Trial
According to the presence or absence of the rudder reference unit, the menu items on
the [Sea Trial] menu change. To open the [Sea Trial] menu, select [Sea Trial] from the
[Installation Menu] window.
Setting for [Mag. Var/]
With a magnetic heading sensor (PG-500/PG-700, etc.), magnetic variation informa-
tion is necessary to display true heading data. In almost all cases, a GPS will be con-
nected to the NAVpilot and the GPS will send this variation information to the NAVpilot
automatically. Therefore, set [Mag. Var.] to [Auto]. In special cases where a manual
variation is required, you may input these values manually. Note that this selection is
only effective when [Heading Display] is set to [True] on the [Display Setup] menu.
When [Heading Display] is set to [True] on the [Display Setup] menu, the NAVpilot will
display true heading information even though the NAVpilot may be connected to a
magnetic heading sensor. This is very valuable when connecting a FURUNO FAR-
21x7 series radar to the NAVpilot because these radars can not be set for a magnetic
heading input and the “Waypoint Lollipop“ will only align properly when true heading
is used.
