Heading Control, the setting of the
maneuver 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 maneuver is
maintained.
- The rudder limit remains at Max.
- Alert Check Settings is displayed
