GDU TXi
Upon power up, GTN begins logging flight data automatically, storing the data
in its internal memory.
GDU streams data to Garmin Pilot via Flight Stream
GDU transfers logs to GTN, which then streams the data to Garmin Pilot
via Flight Stream
GTN is the preferred location for Flight Stream installation
Pilot uses the export function to write GTN data to the SD card
Data logging stops if power is lost. All data recorded up to that point remains
stored in the internal memory. Data is not recorded for the duration of the outage.
When GTN Xi reboots, logging automatically resumes with a new log file.
