Read any flight log, free
ArduPilot, PX4, Betaflight, INAV, DJI, Parrot and CSV logs, read in your browser: the aircraft and firmware, every mode change and error on one timeline, and the flight plotted out. No account needed.
Read any flight log: ArduPilot dataflash (.bin), a MAVLink telemetry log (.tlog), a PX4 ULog (.ulg), a DJI flight record (DJIFlightRecord .txt), a Parrot FreeFlight log (.json), a GUTMA flight log, a flight-log CSV from Litchi, Airdata or a DJI GO conversion, or a Betaflight / INAV Blackbox log (.bbl, .bfl, .txt, or the blackbox_decode CSV). The Log Analyzer tells you what is in the file: the aircraft and firmware it came from, every mode change, event, error and autopilot message on one timeline, and the flight plotted out: attitude, altitude, climb, motors, battery, and vibration. It is free. Your file waits in line to be read, is held only until it is read, and is then deleted; the reading is kept for 24 hours (7 days when you are signed in) so you can leave the page and come back to it.
- The verdict, and how strong the evidence behind it is
- A second-by-second readout of the moments before the event: mixer saturation, descent profile, control authority, battery behavior, and vibration
- Causes ruled in and ruled out, in plain language
- Pilot intent from the RC input, estimator innovation ratios, fitted pack internal resistance, compass interference and accelerometer clipping
- A downloadable report, and the flight filed to an aircraft’s record
