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.
Method of Displaying Numeric Data [TGT DATA]
Procedures 1 Press the [TGT DATA] key.
The cursor mode set the TGT Data.
2 Put the cursor on the tracked target for which numeric data is to be
displayed, and left click.
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 and range will appear
until its vector appears.
z 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 3 minutes or more has passed after such
course change or target acquisition.
Even if 3 minutes or more has passed, the vector may
include an error depending upon the tracking conditions.
