1.24 Electronic Plotting Aid (EPA)
A maximum 10 operator-selected targets can be plotted electronically to assess their motion
trend. Five past positions can be displayed for each of the plotted targets. If you enter a 6th
plot on a certain target, the oldest plot (past position) will be erased.
A vector appears when you enter a second plot for the target and is updated each time a new
plot is entered. The vector shows the target motion trend based on its latest two plots. The
vector origin will move across the screen at a rate and direction defined by the calculated true
course and speed until a next manual plotting.
Target data is shown in the data display area which shows:
bearing, course, speed, CPA, TCPA, calculated true course of targets, calculated true speed of
targets
