FUNDAMENTAL DATA SECTION
TIDE SPEED/DIRECTION Display (text)
Tide speeds/directions of three layers are displayed below the ship’s speed/course.
Depending on the tracking mode in use, the meaning of speed/direction changes as follows
` In the ground tracking mode, speed/direction values represent movement of the layer rela-
tive to ground. [Ground-based tide = Absolute tide]
` In the water tracking mode, speed/direction values represent movement of the layer relative
to near-surface water. Strictly speaking, they do not represent tide but tide differential. [Sur-
face-based tide = Relative tide]
` In the nav-aided mode, speed/direction values represent movement of the layer relative to
pseudo ground. [Ground-based tide = Absolute tide]
(Note that accurate ship’s speed/course and heading information must be applied to CI-35/
35H to obtain reliable tide data.)
To set measuring depth of tide;
Note: Tide speed/direction display is updated every 3 seconds. The display is not raw data for
every 3 seconds, but averaged for specified averaging time. (See page 4-2 to set averaging
time for tide display.)
