The actual heading is taken as the new
set heading. As opposed to manual
change--over from Track Control to
Heading Control, the setting of the ma-
noeuvre parameters might maintain as
under Track Control.
I. e.:
On straight leg:
-- All values will be adopted from
Heading Control mode.
On curved path:
-- The radius planned for the next
track change manoeuvre is
maintained.
-- The rudder limit remains at Max.
-- Alert “Check Settings” is displayed
(see section 1.4.5.1.7.2).

On activating Track Control (see Figure 18 and Figure 19)
-- If the ship (when the Track Control is activated) is already too close to the
TO--WPT and, for geometrical reasons, the intended manoeuvre can not be
realized any more.
