BUILT-IN TEST
There are 3 kinds of Built-In-Tests (BIT) that the IC-600 may perform:
power up BIT, continuous BIT and pilot initiated BIT. All of them check
the software and hardware integrity and operation.
POWER UP BIT
The power up BIT checks the power supply, IC-600 interfaces,
memories, autopilot engagement and disengagement, and autopilot
servos.
CONTINUOUS BIT
Memories and processors tests are continuously performed after the
power up BIT, as well as autopilot functions.
PILOT INITIATED BIT
A pilot initiated BIT may be commanded by pressing the TEST button
in the displays control panel. This test may be commanded on the
ground only and is divided into two levels. The first level is indicated on
airplane displays, which present the failure mode annunciations.
The second level is activated if the TEST button is held pressed, and
checks the IC-600 internal interfaces. The test results are displayed on
the PFD, which alternates every 10 seconds between internal and
external test results pages.
To perform the IC-600 test is necessary to press the TEST button at
co-localized display control panel.
