How to Read a Drone Flight Log

A drone flight log is a time-stamped record of what the aircraft and its sensors were doing. Most logs look intimidating at first because they contain dozens of fields recorded several times per second. You only need a handful of them for a useful review.

The core fields

• Timestamp: when each sample was recorded. Gaps can mean a logging stall or a power interruption.
• Latitude / longitude: the aircraft position. Plotting these produces the flight track.
• Altitude: height above takeoff or above sea level, depending on the source. Always check which reference is used.
• Ground speed: how fast the aircraft moved over the ground, not through the air.
• Heading: the direction the nose was pointing.
• Satellite count / GPS quality: how confident the position fix was.

What commonly goes wrong

Large time gaps, sudden altitude jumps, impossible speed values and long periods with few satellites are the usual warning signs. A single odd sample can be noise; a sustained pattern is worth investigating.

Read the track, not just the numbers

A table tells you the maximum altitude. A map tells you where that altitude occurred, whether the aircraft drifted, and whether the return path was straight. Putting the log on satellite imagery makes those patterns obvious.

Turn a log into a report

Upload a DJI CSV/TXT, ArduPilot .bin or PX4 .ulg file to Drone Flight Report. The tool extracts the core fields, draws the track, checks for anomalies and produces a PDF you can keep or share.
