AnaTele

Evidence-first investigation of ArduPilot flight logs. AnaTele reads Mission Planner .tlog and DataFlash .bin/.log files and turns them into a reproducible investigation:

• What happened? A timeline, armed episodes and flight phases (takeoff, pre-event window, upset, disarm).
• Where did it go? A 3D replay of the recorded path with mission waypoints and their status.
• What looks wrong? A versioned rule pack. Each rule is triggered, not triggered, unassessable or not applicable.
• Why might it have happened? Hypotheses ranked by the evidence for and against each one. No invented probabilities.
• Can I check it? Every claim links back to the exact log record and its raw bytes.
• Can I share it? Save the whole analysis as one .ant file.

Note

AnaTele gives you observations and hypotheses. It is not a crash verdict, a probability of cause or an airworthiness approval. Missing data is treated as unknown, never as healthy.
