(j) Test Button
The TEST button enables the user to initiate a system functional test.
When the TEST button is pushed, the control panel initiates an internal
test while a functional test output is also transmitted through ARINC 429
labels.
When installed with a TCAS system, an extended test can be initiated by
continuously pushing the TEST button for at least eight seconds.
(k) XPDR FAIL Annunciator
The XPDR FAIL annunciator displays the functional status of the active
transponder. The fail annunciator lights only when a failed transponder is
selected on the XPDR 1-2 switch.
E. TAWS Control Panel
The TAWS controls are used to control the displayed terrain data and TAWS inhibit
features. The TAWS control panels may be installed in a single or dual configuration
depending on the TAWS display capabilities.
The TAWS controls can be mounted on a single control panel or they can be discrete
switches individually mounted at a convenient location in the flight deck. The TAWS
controls may be part of the electronic display menu selection in installations where TAWS
information is displayed on an EFIS or electronic display.
