TAS/TCAS SYSTEM FAULTS
NO DATA RECEIVED
If the KMD 250 is not receiving
any data from the TCAS or
TAS sensor then a screen sim-
ilar to Figure 3-8 will be dis-
played. This could indicate that
power is not being provided to
the traffic avoidance system
(e.g. a pulled breaker), a bad
wiring connection between the
display and the sensor, or a
failed TCAS or TAS unit.
SYSTEM TEST
A system test can be performed to verify
the traffic avoidance system is working
properly. If the KMD 250 is configured to
use the Rotary Knob with the traffic func-
tion, turn the outer knob to
select TST. Figure 3-9 indi-
cates a properly functioning
TCAS I/TAS system. An RA
will be displayed for a TCAS II
system. If the KMD 250 not
configured for use of the
Rotary Knob with the traffic
function, this test would be per-
formed using the appropriate
control unit.
If faults are detected in the
KMD 250 or the traffic sensor
they will be displayed as
shown in Figure 3-10. This
figure shows all faults. Only
actual faults will be displayed.
