Self-Test
NOTE: Traffic surveillance is not available during the self-test.
The self-test mode is used to verify that the system is functioning normally.
Self-test must be manually initiated from the Standby mode and takes
approximately ten seconds to complete. During the self-test, a pattern of traffic
symbols is shown on the traffic display. The test pattern consists of the following
traffic:
• A Traffic Advisory at 9 o’clock, 2 miles, 200 feet below and climbing.
There is no Traffic Advisory aural alert for this test traffic.
• A Proximity Advisory at approximately 1 o’clock, 3.6 miles, 1000 feet
below and descending.
• Other Traffic at approximately 11 o’clock, 3.6 miles, 1000 feet above
and level.
Figure 8 Self-Test Mode
If the self-test is successful, the aural announcement “[TAS / TCAS I] System
Test Passed” (depending on the system type) will be played. If the self-test is
unsuccessful, the aural announcement “[TAS / TCAS I] System Test Failed” will
be played.
The system may be installed so that the self-test cannot be initiated while
airborne.
