XCSoar User Manual
During replay, the word “REPLAY” appears at the lower left cor-
ner of the screen. During replay, the program behaves as if real
GPS updates are being received by a GPS. The logger replay dia-
log does not need to be open during replay.
To start a log, first select the file to load, and then select the Start
button. The replay can be performed in accelerated time by chang-
ing the time scale from 1x to a higher number, and paused by set-
ting the time scale to zero. High time scales can result in degraded
performance of the wind estimation and other statistics/analysis
routines.
Stop the log using the Stop . Once a log is started, further presses
of the Start has the effect of restarting the replay.
Note: it is strongly recommended to reset the device before flight,
after a log file has been replayed, in order to ensure that XCSoar’s
internal statistics are properly reset.
When operating XCSoar in FLY mode, the replay is disabled (stopped)
if the real GPS receiver detects that the aircraft is moving.
The logger replay works best with high sampling rate log files; 6
second interval or less works fine.
