Comment/Notes
Both messages swapping.
Two acoustical pulses.
The operating mode changes from Track
Control to Heading Control.
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).
