In this case, this system cannot compute CPA and TCPA, and then does not display the value information.
iii. When ROT indication column is blank, this condition indicates receiving data which cannot be displayed
values. In this case, tuning direction displayed on its turning indicator can be only depended. The turning
indicator is displayed as perpendicular straight line to its heading direction of AIS symbol. (See the section
