Cursor Readout
The cursor readout window is accessed by clicking on the
CURS button, located on the lower popup toolbar.
The readout displays the location of the cursor position relative to the
CCRP of own ship. Readout data appears when the cursor is within any
area of the chart display. If the cursor is moved to a secondary chart
window (see ECDIS Presentation Options) the readout data shown is
applicable to that chart.
The Cursor readout includes the following:
•
Latitude corresponding to the current
cursor position.
•
Longitude corresponding to the current
cursor position.
•
Range - the distance between the
CCRP and the cursor position as
measured in nautical miles (NM).

relative by clicking on the
T or R toggle button.
•

Time To Go (TTG) – the estimated remaining time, displayed as
hours, minutes and seconds, between the CCRP and the cursor
position divided by speed over ground (when in ground stabilised
mode) or speed through water (when in water stabilised mode) .
For information on stabilisation options, refer to Sensor Data
