increased to smooth out the display value in rough conditions or

2.10.5 Course Over Ground
Menu Heading:
WAYPOINT
Function Text: CRSE O/G
Update Rate: Provided by position fixer
Units: Degrees magnetic, true
Note
Requires interfaced position fixer.
Once the position fixer is connected and sending information it
automatically appears in the menu and becomes available for
display. This is your actual track over ground and invaluable to the
navigator for helping him/her to deal with tidal areas.
2.10.6 Dead Reckoning
Menu Heading:
NAVIGATE
Function Text: D/R CRSE or D/R DIST
Update Rate: Once per second
Units: Degrees magnetic, nautical miles
Notes
1. Course and distance.
2. Corrected for leeway if heel sensor fitted.
3. Changeable as a trip function.
Formerly the mainstay of all offshore navigation, now with such
widespread use of electronic position fixing equipment Dead
Reckoning is more often used as an essential back up which can be
particularly effective as an indicator of the net course steered. Both
the course as a bearing from the start point, and its distance in
nautical miles, can be displayed as separate functions.
In the worst case, Man Overboard, immediately resetting the DR will
bring the boat back to the position of entry because DR is the
measurement of course over the water and not over the land as
given by a position fixer.
