Type of Data Display
Target Data
Target identification (TGT ID) ID number of the target
True bearing: BEARING
0.1° unit
Range: RANGE 0.01 NM unit
True course: COURSE
0.1° unit
True speed: SPEED 0.1 knot unit
Closest point of approach (CPA) 0.01 NM unit
Time to CPA (TCPA) 0.1 min unit
Bow crossing range (BCR) 0.01 NM unit
Bow crossing time (BCT) 0.1 min unit
The target for which its numeric data is displayed is marked with a symbol “
” to distinguish from other
targets.
If a target’s data is displayed, but without the symbol “
”, such a target exists outside the currently displayed
radar display.
[I] Method of Displaying Target Data [TGT DATA]
Procedures 1 Move the cross cursor mark onto the target for which numeric data is to
be displayed, and press the [TGT DATA] key.
Then, the data of the designated target will appear, it will be marked with a symbol “
”.
The target data will remain on the radar display until the target is lost and its vector
disappears, or until another target is designated.
If a target with the mark “
” is designated, only its true bearing (BEARING) and range
(RANGE) will appear until its vector appears.
* Buttons and on the radar display on page 2-7 are available to switch target numbers of numeric data.
When a target or own ship changes its course, or when a new
target is acquired, its vector may not reach a given level of
accuracy until three minutes or more has passed after such
course change or target acquisition.
Even if three minutes or more has passed, the vector may
include an error depending upon the. tracking conditions.
