2.1.10.3 FLARM
FLARM is a collision alert system that is popular in many countries outside the USA. It has a built‐in
GPS, pressure sensor and radio transmitter and receiver. It broadcasts its position and altitude so that
other FLARM units in the area will be alerted to its presence. It gives alerts if a collision is predicted
using data received from other FLARM devices in the area.
The ClearNav can display FLARM data on the moving map display.
The FLARM unit can be connected to either of the RS‐232 serial port connectors on the Nexus Wiring
Board. The FLARM to Nexus Wiring Board Cable can be used for the connection. It is shown below.
2.2 Software
The ClearNav runs ClearNavigator software that is specifically designed to work with the ClearNav’s
unique remote control and other hardware. No other soaring software will work on the ClearNav
system.
The ClearNavigator software is designed to be easy‐to‐use in flight and intuitive. Yet it is very powerful
software with many innovative features – such as the glide amoebae and the way it handles turn area
tasks.
2.3 Data Files
The ClearNav uses several types of data files for displaying map information, terrain elevation, airports
and other waypoints, Special Use Airspace, etc. Fortunately, the ClearNav includes a large amount of
memory so that it can hold map and terrain data for much of the world at once. It is important to
make sure that the right data files are installed in the ClearNav so that you will have the best data
available for your area.
