Displays

PowerFLARM Fusion must be connected to a FLARM display. Displays originate from
third party manufacturers implementing the FLARM ICD protocol, an extension of
NMEA 0183. To ensure that collision warnings and traffic information work correctly
and that critical status and error conditions are correctly annunciated to the pilots,
Fusion should be connected to at least one FLARM Compatible display. The display
should be installed in the primary field of view of the pilots. In aircraft with tandem
seating, each pilot should have a display in its primary field of view.
Fusion also supports connections to supplementary displays and navigation
systems over Wi-Fi and Bluetooth.
For detailed requirements for FLARM displays, see the Installation Manual.

Radio Communication and Antennas

The FLARM system uses a radio communication frequency in the SRD860 band
(≈ 868 MHz) or an ISM band (≈ 915 MHz) in different parts of the world.
PowerFLARM Fusion will automatically select the applicable frequency based on the
GNSS position.
The following frequencies are used within the specified areas.
Area
Africa
Australia
Europe
Israel
New Zealand
North America
South America
The antennas should be designed for the frequency band applicable in the
geographic area where the aircraft is being operated. Internal antennas, including
the antennas that are shipped with Fusion, are normally designed for only one of
the frequency bands. The external AV-75 antenna is designed for worldwide use.
Only antennas supplied or approved by FLARM Technology should be used.
Inappropriate antennas, especially antennas without complete insulation, can
damage devices and should not be used.
Note: Fusion will not detect inappropriate antennas, including antennas for the
wrong frequency band.
