Description of LXNAV TrafficView Main Screen is shown on the following picture.
Status of Flarm TX/2, means, that Flarm device transmits data, 2 means, that Flarm
receives data from two Flarm devices.
Flarm identification is 6-digit hexadecimal number, in case that competition sign exists for
that ID, it will be displayed instead of the number.
In case undirected warning is so close, that it can’t be display as described above, warning
looks like on the following picture:
Targets are displayed as various symbols. User can change symbol to another type. It's also
possible to change object colour, depending on relative altitude to the airplane. All received
targets (Flarm or PCAS) are marked with same type of symbol except undirected targets, for

which we don't know what direction are they travelling to. Flarm targets can be separated
only by their ID.

4.7.2 Selecting and switching between targets
Target could be selected using left and right push buttons. If target disappears when it's
selected, TrafficView will still indicate some information about its last known location.
Information about distance, altitude and vario will disappear. If target will appear back, it will
be traced again. In case that function Lock to nearest target is enabled, selection of
targets will not be possible.
4.8 Flarm Warning

for normal Flarm warnings, second one is for undirected/PCAS warnings, third one is for
obstacle warnings.
The screen indicates relative position of threat. In the first image one glider is approaching
from right side (two o’clock) and 120m above.
If modern view is chosen, warnings will be displayed as 3D visualisation of the approaching
threat.

Obstacle warning, upper number indicates the distance to object. Smaller lower number
indicates the relative altitude.
4.9 Traffic list mode
On this page all traffic is displayed in list form. Buttons have similar functionality as on Main
page. In this list we can also see inactive targets, this are targets, which signal was lost.
They will remain on list for time set in setup as target inactive. If target is included in

Page 14 of 22
TCAS layout looks like classic TCAS displays.
Active timeout adjusts remaining time for glider on map after last seen.
Inactive timeout adjusts remaining time of inactive gliders on the list. Inactive gliders are
gliders, which signal was lost, after Active timeout, they became inactive and remains only
on the list.
Line to selected target and selected waypoint can be enabled or disabled in this menu.
If glider vertical distance is less than 100m (330ft), then glider will be painted with near
glider colour. Gliders with vertical distances above that, will be painted with above setting
and below 100m (330ft) will be painted with below setting.
Zoom mode can be set to automatic (zoom to the target) or manual.
If Target label text is selected, near glider will display chosen value.

automatically switch back to nearest target.
If no target is selected Auto select will select to new incoming target. Lock on nearest
has higher priority.
