How To Perform A Trial Maneuver - Furuno FAR-2228-BB Operator's Manual

3. TARGET TRACKING (TT)
Static trial maneuver
The static trial maneuver shows the relationship between your ship and tracked tar-
gets at the completion of the trial maneuver. The expected position of TTs at the end
of the trial maneuver are shown on the display.
By shortening and extending the trial time you can find the safe time to make a ma-
neuver. Thus, the static trial maneuver will be convenient when you wish to know the
maneuver result immediately.
