1 INTRODUCTION
Last flight statistics
The previous flight’s statistics are automatically saved when XCSoar is shut down, and loaded
again at startup. This allows the flight to be reviewed even after shutting down Altair. Note that
these persistent flight statistics use approximately 85 kilobytes of storage.
Previous flight statistics are automatically reset on a new takeoff in order not to affect the current
flight.
Persistent settings
The basic settings (MacCready setting, Bugs, Ballast, QNH, maximum forecast temperature) are
preserved when XCSoar shuts down and restored when XCSoar initialises.
Exiting the program
To shut down Altair (XCSoar), press the PWR/ESC button for approx. two seconds and confirm the
shutdown process by pressing YES on the dialog that comes up.

Troubleshooting
A small team of dedicated developers produces XCSoar. Although we are happy to help with the
use of our software, we cannot teach you about basics of modern information technology. There
are ample existing resources dealing with these. If you have a question about XCSoar please email
us at xcsoar-user@lists.sourceforge.net.
You may find some solutions to standard problems in the Frequently Asked Questions (FAQ) section
of the XCSoar website.
Furthermore, we recommend to subscribe to the XCSoar users mailing list so you will be kept up
to date with latest developments.
A log file of the startup functions of XCSoar is generated to the file xcsoar-startup.log. This
is transferred to the ‘FromAltair’ directory by AltairSync if a USB drive is plugged in when Altair is
first switched on. It can then be sent to the XCSoar developers to help determine the cause if the
program crashes at startup.
XCSoarPC
XCSoarPC may be used to become familiar with XCSoar’s interface and functionality in the comfort
of one’s home. All files and configuration used by XCSoarPC are identical to the Altair versions, so
it can be helpful to try out customizations on the PC version before using them in flight.
XCSoarPC can also be connected to external devices and operates just as Altair does. Suggested
uses include:
• Connect the PC to a FLARM device to use XCSoarPC as a ground station display of
FLARM-equipped traffic.
• Connect the PC to an intelligent variometer such as Vega to test configuration settings of
the variometer.
