Log Viewer (Analyze View)

The Log Viewer screen (Analyze > Log Viewer) provides a unified workflow for post-flight analysis:

• Open ArduPilot DataFlash logs (.bin/.log) for parameter and event inspection.
• Open telemetry logs (.tlog) and replay them with timeline controls.
• Reuse existing MAVLink inspection and charting tools while replaying telemetry.

Typical Workflow

1. Download logs from Analyze > Onboard Logs.
2. Open the downloaded .bin or .tlog file in Analyze > Log Viewer.
3. For .tlog, use playback controls (play/pause, speed, seek) to inspect behavior over time.
4. For .bin, review extracted parameters and events, then select signals for plotting.

Performance Notes

• Very large logs can take noticeable time to parse.
• Prefer loading logs from local SSD storage for faster indexing.
• If onboard storage is slow and logs contain gaps, reduce logging rate using related parameters in Analyze > Log Setup.
