XCSoar User Manual
• The PRO version of Altair has an internal IGC certified log-
ger device. XCSoar communicates with the logger as if it
were an external serial device.
• XCSoar can also send declarations to some external logger
devices, such as the EW logger. For this to work, the device
name must be specified in the “COMM ports and Devices”
section of the configuration settings.
The logger can be turned on and off automatically or manually. To
turn the logger on or off manually, select from the menu
CONFIG . Logger Record
When the internal software logger is active, a small diamond in
the lower right corner of the map area flashes once per second.
By default, XCSoar is set up to automatically start and stop the
internal software flight logger when it detects the aircraft is flying
and when it has landed, respectively. Only when the logger is
manually started does it ask if the flight is to be declared; when
automatically starting it automatically declares the current task.
If a task has been declared, then subsequent attempts at modifying
the task result in a warning message asking to confirm whether
the action is to be taken and invalidate the declaration. This is
intended to make it harder to accidentally modify the task resulting
in a failed declared task.
The XCSoar software logger, when started, checks for 500kB of
free space on the file storage. If there is insufficient space, it
will automatically delete IGC files, oldest first, in order to free
up 500kB. It asks the user for confirmation before performing this
operation.
4.14 Logger replay dialog
Flight logs in the IGC format generated by XCSoar or other log-
gers can be replayed. The logger replay dialog can be accessed via
the menu:
