6.6 Operation of the EPA

The EPA (Electronic Plotting Aid) provides the information for collision avoidance by
manually plotting the first and second positions of each target. These include:
CPA (Closest Point of Approach), TCPA (Time to Closest Point of Approach), Ship's
speed, Ship's course and Ship's vector

6.6.1 Using the EPA

Perform the following procedure to use the EPA function:
(1) Move the Joystick to move the cross cursor to a target for plotting.
(2) Press the ACQ key to acquire the target. The assigned target is braced with a
dashed acquire mark with the figure 1 shown nearby.
(3) After 30 seconds or more since the target has been acquired, plot the target again
as a second plot by placing the cross cursor on it and pressing the ACQ key. A
vector will be developed and the relevant data will be shown on the right side of the
screen. (Refer to Figure 6.2)
(4) Press the DELETE key to cancel the target tracking. The symbol of the target and
data will be cleared.
