Fuel range rings
The fuel range ring gives an estimated range that can be reached
with the estimated fuel remaining on-board.
The fuel range ring can be displayed graphically in the chart
application and indicates an estimated range that can be reached
with the:
• Current rate of fuel consumption.
• Estimated fuel remaining on-board.
• Course remaining in a straight line.
• Current speed maintained.
Note:
The fuel range ring is an estimated range that can be reached
at the current rate of fuel consumption, of the fuel onboard and
based on a number of external factors which could either extend
or shorten the projected range.
This estimate is based on data received from external fuel
management devices, or via the Fuel Manager. It does not take
into account prevailing conditions such as tide, current, sea state,
wind etc.
You should not rely on the fuel range ring feature for accurate
voyage planning or in emergency and safety critical situations.
