The traffic symbols on the
traffic display are non-direc-
tional (diamond shape)
Non-directional traffic symbols on
the traffic display is due to one of
the following reasons:
The directional information that
is being received by the MSS
does not have directional data.
The MSS continues to transmit
non-directional data to the traffic
display.
An alternate traffic display (if
installed) does not support the
DTIF data format necessary to
show directional data provided
by ADS-B.

2.
Traffic display is working
correctly, but aircraft are not
showing up on the display.
Lack of data as described below:
The ADS-B In requires other
aircraft to be equipped with ADS-
B Out.
The TIS-B and ADS-R services
are supported when in range of
ground stations providing the
service.
If receiving the TIS-B
service, Mode C and Mode S
transponder equipped aircraft
that do not provide altitude
information are not seen on the
traffic display.
If receiving the TIS-B service,
but aircraft not equipped with a
transponder, or equipped with a
Mode A transponder are not part
of the TIS-B data and will not be
seen on the traffic display.

No TIS-B or FIS-B Coverage
Indicator is showing, but a
aircraft is in coverage area.
The Lynx NGT-9000 or a system
component may have failed or
degraded.
