the Autopilot received WPTs whose radii are closer together than 350m or the
difference of the track courses is >135
An alert is displayed at the top bar of the display (see section 6).

two pulses
The operating mode changes from
Track Control to Heading Control.
The track course becomes set course
(preset heading). As opposed to
manual change--over from Track Con-
trol to Heading Control, the setting of
the manoeuvre parameters might main-
tain 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).
If during automatic change--over from
Track Control to Heading Control -- the
ship is in a track change manoeuvre,
the track course of the next track sec-
tion is taken as the new set course
(preset heading). The radius planned
for the current track change manoeuvre
is taken as manoeuvre parameter.
