3. TARGET TRACKING (TT)
3-20
3.15 TT Performance Test
A test program is provided for assessing overall performance of the TT. Normal oper-
ation is suspended and the indication "S" appears at the bottom of the effective display
area during the test. The test may be terminated at any time.
1. Open the menu then select [8 INITIAL SETTING] and [8 TT TEST].
2. A window asks if you are ready to start the TT test. Click the [OK] button to start
the test.
"S" flickers during the test. It takes approximately three minutes for all vectors to be
displayed. The test does not need echo signals, gyro nor speed log input. Three tar-
gets having different speeds and courses, as shown in the table below, are simulated
automatically, together with current targets. These targets can be treated as you
would an ordinary TT - you can cancel them, display their data, etc.
The test continues for ten minutes and repeats.
To terminate the test, push the STBY TX key on the Control Unit or click the [STBY/
TX] button on the Status bar.
Select any simulated target with the cursor and check that the selected target shows
the course and speed as in the table. CPA and TCPA shown in the table are with ship's
speed of 0 kn. These values change with time and own ship's movement.
The bearing and course values are when the heading is 0°.
