Flying with the System

To get the best out of the system it is important that some preparation is done prior to take-
off. Trying to configure the instrument or set a task while flying is very hazardous especially
in a competition. At least, it could spoil your whole day! Pre-flight preparation will ensure
that the flight will be both safe and enjoyable.

6.2 On the Ground

6.2.1

Power-On Procedure

Press the power-on button. The main display unit and the vario unit will turn on and a few
moments later welcome screen will appear. The first screen shows the version of the boot
loader followed by the version of the Linux kernel operating system, then the version of the
file system. The boot procedure normally takes 10 seconds. When completed the profile
selection dialogue is shown.
It is recommended to switch the unit ON some minutes prior to take-off to give
the GPS receiver time enough to acquire satellites. The flight recorder will also
make a take-off baseline. Longer running on the ground will not reduce flight
recorder capacity.

the SD card/USB stick by a small SD card/USB stick symbol in the lower-right part of the
pilot icon.
For the selected profile the pilot name, glider type, loaded waypoint files, loaded airports
databases and loaded airspace databases are shown.
If a file is stored on a SD card or USB stick, a label [SD] or [USB] will appear in front of file
name.
