Can be independently reset as a trip function.

Formerly the mainstay of all offshore navigation, now with
such widespread use of electronic position fixing equipment
it is more often used as an essential back up.

It can be particularly effective as an indicator of the net
course steered on long offshore legs. Calculated from a base
point, which is set when you start the function running, (see
Para 2.3.3 for details of control) both the course as a bearing
from the start point, and its distance in nautical miles, can be
displayed as separate functions. If the heel angle sensor is
fitted then the Course calculation will include leeway
correction.

In the worst case, a Man Overboard (MOB) situation,
immediately resetting the Dead Reckoning (DR) will bring
the vessel back to the MOB position. DR is the course and
distance over the water and not over the land as would be
given by a position fixer.
