KMD 250 Pilot’s Guide
Section 3
Traffic Avoidance
Traffic will not be available in
the Data Field if the Map
Orientation is set to North Up.
It the Map Display is in North
Up mode, the Traffic Data Field
will appear as shown in Figure
3-19.
COAST MODE
When intruders are displayed
and TIS information is not
received from the terminal
Mode S radar for one radar
scan, the altitude tag of the
intruder is replaced with the
text CST to inform the pilot that
the system is in Coast mode.
See Figure 3-20. CST will also
be displayed in the Traffic Data
Window. This means the dis-
played intruder information is
old and could have changed
since the last update.
When two radar scans have
elapsed without TIS informa-
tion, the intruders are removed
from the display and TIS
UNAVAILABLE is displayed in
the center of the Traffic Display
(Figure 3-21) or UNAVAIL will
be displayed in the Traffic Data
Window. Also, an audible "TIS
UNAVAILABLE" notification will
be heard (if not muted). The
display will revert to normal
when TIS information is again
available.
