8 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 the least, it could spoil your whole day! Pre-flight preparation will
ensure that the flight will be both safe and enjoyable.
8.1 On the Ground
8.1.1 Power on Procedure
Press the power-on button. The main display unit and the vario unit will turn on and 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.
8.1.2 Profile Selection
Turn the PAGE selector knob to select the desired profile if more than one profile is
available. First profiles stored in internal storage are displayed, next profiles on SD card are
shown and at last profiles on USB stick are shown. You will note profile resides on SD
card/USB stick with small SD card/USB stick symbol in lower right part of 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 SD card or USB stick, label [SD] or [USB] will be in front of file name.
To learn more about profiles refer to Chapter 6.1.14. Press the SELECT button to confirm
selection of the profile. Press DEFAULT button to start the system with default settings.
The set elevation dialogue will be shown next.
