The Navigator has a command "Report range at current speed" which does just what it says. (I don't recall where this command is located, as I always use voice command, but it shouldn't be too hard to find.) Experiment with various speed settings during transition to your patrol area. Always allow time for the speed to settle after you change settings, as the Nav will only give you the range at current instantaneous speed, not the speed requested. Make sure you are in fairly calm seas. Then make a rough estimate of the distance from your patrol area to the refueling base you plan to use. R/L, RTB (at most efficient speed) + 10% (of total fuel range) is considered "Bingo", the point at which all offensive action should cease and the vessel should return home. Keep querying the Nav about range remaining so you know your operational flexibility, and adjust your plans if bad weather increases your fuel consumption. Always consider your fuel status when making tactical/operational plans.
