Replay Flight Data
This feature is intended primarily for autopilot developers/vehicle creators. It is only supported on desktop builds (Windows, Linux, Mac OS).
The Replay Flight Data features allows users to replay a telemetry log, enabling review of past or problematic flights. The flight can be started, paused, stopped, restarted etc.
QGroundControl treats flight replay like an active connection. When you pause/stop playing, the ground station will report "Communication Lost" and wait for disconnection or for more messages.
To replay a flight:
- Disconnect any active connections.
Select File | Replay Flight Data to toggle the flight replay bar visibility.
Select the Replay Flight Data button in the bar to display a file selection dialog. Choose a log file to replay from the available telemetry logs.
QGroundControl will immediately start playing the log.
Use the pause/reset button to control playing. When paused you can move the slider to a new position in the log.
You can pause the flight and select Disconnect to stop replay. At this point you can select an alternative log to replay.
