Replay Flight Data
::: warning 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 feature allows users to replay a telemetry log, enabling review of past or problematic flights. The flight can be started, paused, stopped, restarted etc.
::: info 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 Application Settings > General > Fly View
-
Check Show Telemetry Log Replay Status Bar to toggle the flight replay bar at the bottom of the screen.
-
Select the Load Telemetry Log 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.
-
When a log is loaded you can use the:
- Pause/Play button to pause and restart playing.
- Slider to drag to a new position in the log.
- Rate selector to choose the playback speed.
-
To stop replay (i.e. to load a new file to replay), first pause the flight, and then select Disconnect (when it appears). After disconnecting, the Load Telemetry Log button will be displayed.
:::tip You can inspect the running replay in more detail using the MAVLink Inspector. :::
