Dynamic trial maneuver
Note that once a dynamic trial maneuver
is initiated, you cannot alter own ship's
trial speed, course or delay time until the
trial maneuver is terminated.
Static trial maneuver
A static trial maneuver displays only the
final situation of the simulation. If you en-
ter the same trial speed, course and de-
lay time under the same situation as in
the aforementioned example of dynamic
trial maneuver, the screen will instantly
show position OS7 for own ship, position
A7 for target A and position B7 for target
B, omitting the intermediate positions.
Thus, the static trial maneuver will be con-
venient when you wish to know the ma-
neuver result immediately.
Note: For accurate simulation of ship
movements in a trial maneuver, own ship's
characteristics such as acceleration and
turning performance should be properly
set in initial settings at the time of instal-
lation.
To perform a trial maneuver:
1. Press the E, AUTO PLOT MENU key
on the plotting keypad followed by the
[0] key to show the ARPA 2 menu.
