8.1 FLARM

Before using FLARM it is highly recommended to read the FLARM user manual
which can be downloaded from www.flarm.com. Respect all limitations listed in
this document.
FLARM is a collision avoidance system developed by FLARM Technology AG from
Switzerland. The FLARM module consists of following main parts: GPS receiver,
microcontroller unit, radio transceiver pressure altimeter and optional an external indicator.
All electronic parts are integrated into the main display unit cabinet. An exception is the
radio communication antenna and the FLARM External Display. Some input is possible via
the external display.
If the display unit does not have built FLARM, an external FLARM connection is
possible using the LX5flarm or LX5PF cable for Power FLARM.

Installation

For more detailed instructions on installation, please refer to the installation
manual.
The position of the radio communication antenna is extremely important as a bad
installation will reduce the system range dramatically. It is highly recommended to install
the antenna on the top of the instrument panel with a suitable aluminium round plate
having a diameter of about 12 cm used as a back plane and an approximately 10 cm long
rubber antenna used as the radiator. The metal plate may be mounted outside or inside of
the instrument panel. If carbon is used, use only the top mounting variant.
