2.1 Device overview
The LX Traffic Square is a collision avoidance flight display compatible with all types of
Flarm devices. It is commonly used in gliders, ultralights and experimental aircraft. Additional
to providing audio and visual collision avoidance warnings and a Flarm radar display, the
Traffic Square offers the pilot two dedicated moving map navigation pages. These pages
offer simultaneous navigation to a Turnpoint and Airport.
Using a Flarm device with an ADS-B module will offer the pilot ADS-B warnings as well.
It offers the same functionality of the LX Traffic Monitor, but in a more compact square package.
The device features a transflective technology display.
NOTE
Find out more about transflective technology displays and why this technology is
so important in air navigation in our Whitepaper on transflective technology
The LX Traffic Square’s primary function is to alert the pilot of an on-coming collision with
audio and visual warnings. The secondary function is to show the pilot all Flarm and ADS-B
(if an ADS-B module is installed) objects on the Flarm radar page and the tertiary function is
to act as a simple navigation device.
The device is designed for simple pilot operation with a single 4-way push-button that features
both short and long-press functions.
The unit is capable of providing APT (airport) and TP (turnpoint) navigation on two dedicated
navigation pages. Navigation pages feature navboxes, showing bearing to point, track,
distance, ground speed and altitude. It also shows airspace, airports and turnpoints on the
map.
There is a dedicated logbook page, listing all flights with date, take-off and landing times and
flight duration.

Basic operation
We will go through the basic gestures and what they do on all pages of the LX Traffic Square
system.
The Traffic Square uses a single 4-way push button with both short and long-press functions.
3.1 Turning the LX Traffic Square on
The LX Traffic Square is turned on automatically when power is supplied to the Flarm port,
meaning it does not have a turn-on and shut-down option.
Once the device is turned on, a sequence of screens will appear in the following order:
•LX navigation greeting screen
•Second screen stating the device type, serial number and firmware version
WARNING
When the device is turning on, a warning may appear, indicating limited operation
capability to the pilot. You should contact LX support as soon as possible. The
device might be operable even with the warning present, but full operational
capability is not guaranteed.
•Internal memory error - there is an issue with the internal memory of the
device. Device will continue to operate and show Flarm warnings, but some
pictures and assets may be corrupted.

4.1 Flarm radar page
The Flarm radar page shows all surrounding objects reported to the LX Traffic Square by a
Flarm device. If the said Flarm device has an ADS-B module, the LX Traffic Square will show
ADS-B objects as well. Flarm objects are shown on a radar screen with track-up orientation.
Figure 2. Flarm radar screen Figure 3. Flarm radar select circle
Objects presented as a dot on the screen are objects where pilots have intentionally activated
the PRIVACY mode on their Flarm unit. Objects in privacy mode send limited data strings and
can’t be visualized completely. However, all warnings will appear regardless of privacy mode.
It will also display ’non-directional’ traffic. This is traffic reported by some Flarm devices with
built-in ADS-B receiver capable of receiving Mode-S transponders (example of such a device
is LX navigation Flarm Eagle with ADS-B). Non directional traffic is displayed as a circle
around the object.
Short-pressing the push-button will invoke the selection of a Flarm object to follow. For a
selected object, relative altitude, distance, ground speed and vertical speed of object will be
displayed on the screen, as depicted on Flarm radar select circle picture.
Moving the push-knob up and down will change the zoom of the flight radar screen and
long-pressing it will open the Flarm objects sub-page. In the Flarm sub-page, a list of all visible
aircraft is shown. A green dot next to the name of the object shows which object has been
select for additional info on the Flarm radar page. Object ID and distance is also shown.
By choosing an object and pressing the push-button, additional information can be seen and/or
edited, for each object:
•Callsign
•Pilot
•Airfield
•Registration number
•Frequency
•Flarm ID (always non-changeable)

An important safety feature of the LX Traffic Square is the Flarm warning page. This page
pops-up whenever the Flarm device sends a warning sentence, regardless of the menu, page
or setup you’re currently in.
Figure 6. Flarm warning page
The Flarm warning screen shows the type of object the Flarm is warning you about, from the
list of supported Flarm objects (Glider shown on figure). It’s relative direction to your heading,
relative altitude and distance, as well as an angle from the horizon, with the blue/brown scale
on the left side of the screen. The relative direction of the object is also written in word with
GLIDER 12 O’CLOCK ABOVE.

NOTE
A lot of effort was put into the design of the Flarm Warning screen, shown by
figure 34. It’s sole purpose is to quickly familiarize the pilot with the potential
danger. Flarm provides us with three distinctive levels of danger:
•13 to 18 seconds to impact - the Flarm Warning screen appears, the LX
Traffic Square’s internal beeper and the flashing of the direction cone are in
the same, steady frequency. The lady from the LX Traffic Square’s internal
voice module notifies you of the location of the object.
•9 to 12 seconds to impact - same as previous level, both the internal beeper
frequency and beeping interval, as well as the flashing interval, intensify
(higher frequency)
•0 to 8 seconds to impact - as on previous level, with the highest frequency
of beeping and flashing.

4.2 Navigation pages
The LX Traffic Square offers 2 separate navigation pages, giving the pilot simultaneous
navigation to a turnpoint & airport.
The basic layout of each navigation page is the same. In the top of the page, we can see the
header. Below the header, we can see the moving map. A zoom scale is present and in the
bottom of the page, the NavBox line is positioned.
Long-pressing the push-knob will show additional info for the point we’re currently navigating
to on the tunpoint & airport. Moving the push-knob up and down will change the zoom level.
Short-pressing the push-button will open the turnpoint or airport selection sub-page.
4.2.1 The map
The Turnpoint navigation page is based on a map, covering the central part of the screen. The
map shows turnpoints and airports with small circles and their names, as well as airspace
lines.
On the Map, an aircraft icon represents your current location. The LX Traffic Square supports
both North-up and Track-up orientation, which can be set in the Graphics section.
On the right, the map scale is shown.
Figure 7. A navigation page
Two lines can be seen on the screen, starting at the aircraft. The first one is showing the
direction of your movement, your track, and the second one is showing the direction to your
chosen turnpoint, the destination line. Colours can be changed in the Graphics setup menu.
4.2.2 The Header
The Header represents the top part of the screen, covering three vital pieces of informa-
tion:Page name, Turnpoint name and Relative bearing.

In the far top of the screen, we can see ’TP:’ written. The TP indicates that we are on the
Turnpoint navigation page. After the colon, the name of the turnpoint to which we are
navigating to is displayed.
Next to the turnpoint name, relative bearing is shown in degrees. When the relative bearing is
0, we are flying towards the turnpoint.
Since the relative bearing is calculated from the bearing to turnpoint and your current track
(not heading), the wind is already calculated into the relative bearing.
On either side of the relative bearing, a green arrow will show in which direction you should
turn by the noted amount of degrees in order to be on course for the turnpoint.
4.2.2.1 The NavBox line
In the lower part of the screen a NavBox line containing 4 NavBoxes is shown. Ground
speed, Track, Bearing and Distance to turnpoint are shown.
