Description

–

Auto/Man Switch

This discrete toggle switch is only required for some alternate
displays. This switch allows you to select TCAS auto mode or
TCAS manual mode.

TCAS auto mode allows a non-TCAS display page to be
automatically interrupted when a TA occurs. TCAS information
will pop up on the display and remain displayed until several
seconds after the traffic is no longer a threat. The display will then
revert to the function that was selected before the TA occurred.

TCAS manual mode prevents the display from being interrupted by
TCAS information. When a TA occurs, the aural message will still
be announced, but the visual TCAS information will not be
displayed (unless TCAS was already selected on the display).

–

TA ONLY Indicator

Whenever the TCAS791 is on and not displaying a failure and not
in standby, some of the alternate displays will display the TA
ONLY indicator on the screen. This indicator means that the
display is either connected to a TCAS I system or to a TCAS II
system in TA ONLY mode. In both cases, the implication is that no
resolution advisories will be issued. On some alternate displays,
when an active TA is detected, the background color of the TA
ONLY indicator changes from white to amber.

–

TCAS FAILED or TCAS FAIL Indicator

The CD605 will display the message TCAS FAILED when the
TCAS791 detects a failure and after an operator-initiated self test
failure.

On some alternate displays, the message TCAS FAIL will be
displayed whenever the TCAS791 is not powered up. These
alternate displays will continue to display TCAS FAIL for several
seconds after the TCAS791 is turned on. The TCAS FAIL message
may also appear on the alternate displays if there’s a TCAS failure,
or if the TCAS791 fails a self test. It is also possible for an alternate
display to display TCAS OFF instead of TCAS FAIL after a self
test failure on the ground.

–

TCAS OFF Indicator

The TCAS OFF indicator is displayed on some alternate displays. It
indicates that the TCAS791 is in standby. It does not mean that the
TCAS791 has been turned off.
