4 System Description
4.1 Push buttons on FlarmView
With four push buttons, it is possible to zoom, choose between targets, and adjust FlarmView settings. In some cases, a long press on a button has a specific function. For example, a long press on the upper button moves the cursor one position to the left. A long press on the lower button cancels all changes.
Image Description: An example screen shows "Edit FlarmNet Data" with fields for Flarm ID and Competition ID, and buttons like "Ok" and "Cancel".
4.2 Rotary encoder with push button on FlarmView57
Using the rotary switch is easier than four buttons. With the rotating knob, the user can select targets, edit numbers, names, etc. A short press confirms an action (ENTER or OK), while a long press cancels (CANCEL or ESC). Changing between different zoom levels and pages is possible by pushing and rotating together.
4.3 Switching on the Unit
The unit switches on immediately after receiving power supply from an external Flarm/ADS-B device. The welcome screen displays information about the version and serial number.
4.4 User Input
The LXNAV FlarmView user interface consists of many dialogues with different input controls designed for easy input of names, parameters, etc. Input controls include:
- Text editor
- Spin controls (Selection control)
- Checkboxes
- Slider control
To move between controls, use the up or down buttons. Pressing the "Edit" button accesses the displayed control.
Image Description: A "Target Settings" screen is shown, displaying controls for "Active Timeout", "Inactive Timeout", "Line to target", and "Enabled", with "Edit" and "Close" buttons.
In FlarmView57, "up" and "down" mean rotating left and right the knob. A short press acts as "Edit", and a long push acts as "Close".
4.4.1 Buttons on FlarmView
Buttons have dynamically set functions. When a button is pressed, blue labels appear on its side indicating the assigned action. On the main screen, the top button always switches between pages. A short press cycles pages in one direction, while a long press cycles in the opposite direction. The zoom level is indicated by a number showing the outer circle radius (2km, depending on distance units). The inner circle is half of that distance.
Image Description: A radar screen display shows traffic information with Flarm ID, distance, vertical speed, and altitude. It also shows a zoom level indicator.
Middle buttons help with target selection by cycling through available targets. The lower button has a ZOOM back or EDIT function with a long press, allowing the user to edit or view the currently selected target.
Image Description: A radar screen display shows traffic information with Flarm ID, distance, vertical speed, and altitude. It also shows a zoom level indicator.
4.4.2 Text Edit Control
The Text Editor is used to input alphanumeric strings. The image shows typical options when editing text. Use the up/down buttons to change the value at the current cursor position.
Image Description: An "Edit FlarmNet Data" screen is displayed, showing fields for "Flarm ID" and "Competition ID", with an input cursor in the "Competition ID" field.
The "next" push button moves the cursor right. A long press on "next" moves the cursor left. At the last character position, a push button confirms the edited value. A long press on "Ok" cancels editing and exits the control. If a long press is available, part of the button label is in gray. For example, the top button's long press ">> B" has a back function. The bottom button's long press has a Cancel function. The Flarm ID field is not editable as it is a unique Flarm identification number.
On FlarmView57, users can enter Edit mode with a short press. Rotating the knob changes characters. A short press confirms the current character and jumps to the next position. A long press finishes editing the field. Pushing and rotating moves the cursor left and right.
4.4.3 Selection Control
Selection boxes, also known as combo boxes, are used to select a value from a list of predefined values. Use the up/down buttons to select the appropriate value.
Image Description: A "Units" selection screen is shown, with options for Distance (km), Altitude (m), and Vertical speed (km/h).
4.4.4 Checkbox and Checkbox List
A checkbox enables or disables a particular parameter. Press the "EDIT" button to toggle the value. If an option is enabled, a check mark ☑️ is shown; otherwise, an empty rectangle is displayed.
Image Description: A "Sounds" configuration screen is shown, with checkboxes for "low alarm", "important alarm", and "urgent alarm", each with a "Beep on" option.
4.4.5 Slider selector
Some values, like volume and brightness, are displayed as a slider.
Image Description: A "Target Settings" screen is shown, with a slider control for "Active Timeout" (currently set to 68).
With "Edit", you can activate the slider control. Then, using the up/down buttons, you can select the preferred value and confirm it with the "Ok" push button.
4.5 Operating Modes
LXNAV FlarmView has four operating pages: the Main radar screen with different zoom levels, the Flarm traffic list, and the Setting Page. The fourth page, "Flarm watch", is displayed automatically if Flarm detects a potential collision situation and issues a warning.
- Main radar screen: Shows all visible objects and their information (ID, distance, vertical speed, and altitude), status of Flarm (TX/2).
- Flarm Traffic list: Displays traffic in textual format.
- Settings: Setup of the whole system.
- Flarm Watch: Shows the direction of any threat.
4.6 Main screen
The LXNAV FlarmView Main Screen is described below. Image Description: A detailed diagram of the main radar screen is shown, with labels pointing to various elements: "Status of Flarm", "Flarm identification", "Distance to selected target", "Vario of selected target", "Relative Alt to target", "GPS status", "Selected object", "Label set in target menu", "Undirected warning from AC mode", and "Zoom level".
Status of Flarm: TX/2 means the Flarm device transmits data (TX) and receives data from two Flarm devices (2).
Flarm identification: This is a 6-digit hexadecimal number.
GPS status: Indicates the status of the Flarm's GPS receiver. The number of painted bars counts the satellites received. Green bars indicate GPS 3D status, yellow indicates GPS 2D, and red indicates GPS BAD. "N.C." means that FlarmView does not receive anything from Flarm.
Zoom level: Indicates the current zoom setting on the radar.
Image Description: A radar screen display shows traffic information with Flarm ID, distance, vertical speed, and altitude. It also shows a zoom level indicator.
Image Description: A "Flarm Traffic 1/3" list view is displayed, showing competition IDs (CD, AL, DD9C78) with distance and vertical speed information.
In case an undirected warning is very close, the warning display may look different, as shown in the following picture. Image Description: A radar screen display shows a warning with a target identified by Flarm ID DD9C78, distance, vertical speed, and altitude.
All targets are displayed as glider symbols. The user can change the symbol to another type. It is also possible to change the object color depending on relative altitude. All received targets (Flarm or PCAS) are marked with the same symbol type, except for undirected targets, for which the direction is unknown. Flarm targets can be separated only by their ID.
4.6.1 Flarm symbols
Image Description: A list of Flarm symbols is displayed, with corresponding aircraft types: Unknown, Glider, Tow plane, Helicopter, Parachute, Drop plane, Hang glider, Para Glider, Powered Aircraft, Jet Aircraft, Balloon, Airship, UAV.
4.6.2 Selecting and switching between targets
Targets can be selected using the Up/Down (middle two) buttons. If a selected target disappears, FlarmView will still indicate some information about the last selected target. Information about distance, altitude, and vario will disappear. If the target reappears, it will be traced again. If the "Lock to nearest target" function is enabled, target selection may not be possible (See Ch.4.9.3).
4.7 Flarm Warning
If Flarm warnings are enabled, the following is a typical screen display. The first two are normal Flarm warnings, the third is for undirected/PCAS warning, and the last is for obstacle warning.
Image Description: Four radar screen displays are shown, illustrating different warning scenarios. The first two show multiple targets with distance and directional indicators. The third shows a single target with distance and directional indicators. The fourth shows a target with distance and directional indicators, indicating an obstacle warning.
The screen indicates the relative position of the threat. In the first image, two gliders are approaching from the left at the same altitude, and one from the back right. The second screen shows one glider approaching from the right (4 o'clock). The third screen is an example of an undirected warning (AC mode). The middle number shows the horizontal distance to the target, and the last picture indicates an obstacle warning.
4.8 Traffic list mode
On this page, all traffic is displayed in list form. Buttons have similar functionality as on the Main page. In this list, inactive targets (those from which signals were lost) are also shown. They remain on the list for a time set in the "target inactive timeout" setting (which is configurable). If a target is included in the FlarmNet database or UserDatabase, it will appear on the list under a user-friendly name (e.g., Competition Sign (CD, AL)). If the target is not in the FlarmNet or UserDatabase, it will be displayed with its FlarmId code.
Image Description: A "Flarm Traffic 1/3" list view is displayed, showing competition IDs (CD, AL, DD9C78) with distance and vertical speed information.
4.9 Settings Mode
In the setup menu, users can configure the LXNAV FlarmView. Use up/down to select the appropriate setup item and press the "Select" button to enter a menu. A dialogue or sub-menu will open.

For better readability, the background can be set to Black or White.
Image Description: A radar screen display showing a target at 138m with directional indicators.
If you want the buttons on the left side, the complete screen can be rotated.
If "always hidden" is checked, the button labels are not displayed on main screens.
4.9.2 Warnings
Warnings can be enabled for three different levels (low, important, and urgent), separately for A/C (undirected warnings can be enabled), and also a distance for A/C warning, where "Flarm watch" will be displayed. If "Alert on A/C mode" is disabled, the A/C mode distance is not applicable.
Image Description: Two "Warnings" configuration screens are shown, allowing users to enable "low", "important", "urgent" alarms, and "A/C mode" warnings, with an option for "A/C mode dist. (km)".
Please keep in mind that a bad A/C receiver or false A/C information can be distracting on FlarmView. To avoid such situations, you can uncheck alerts on A/C mode at any time.
For the first 3 minutes, there won't be any warnings.
The warnings are classified into three levels (See Flarm manual for details on www.flarm.com):
- First level (Low): approximately 18 seconds before predicted collision.
- Second level (Important): approximately 13 seconds before predicted collision.
- Third level (Urgent): approximately 8 seconds before predicted collision.
4.9.3 Target
Active timeout: Adjusts the remaining time of a glider on the map after it was last seen. Inactive timeout: Adjusts the remaining time of inactive gliders on the list. Inactive gliders are those from which the signal was lost; after the Active timeout, they become inactive and remain only on the list.
If a glider's vertical distance is less than 100m (330ft), it will be painted with the "near glider color". Gliders with vertical distances above that will be painted with the "above" setting, and below 100m (330ft) will be painted with the "below" setting.
Zoom mode: Can be set to automatic (zoom to the target) or manual.
If "Target label" is active, the near glider will display the chosen value.
Show A/C range: Shows the A/C ring on the Flarm radar screen.
Lock on nearest: Automatically selects the nearest target and displays its data. If you want to select another target, it's possible. After 10 seconds, FlarmView will switch back to the nearest target.
If no targets are selected, "Auto select" will select the next incoming target. "Lock on nearest" has higher priority.
Image Description: Multiple "Target Settings" screens are shown, covering options like "Glider Image", "Color of glider above/below", "Zoom mode", "Target label", "Active Timeout", "Inactive Timeout", "Show A/C range", and "Lock on nearest".
4.9.4 Sounds
