Every flight is recorded stage by stage — ↑ takeoff, → each leg between waypoints, ↓ landing — and Flight Reliability aggregates those stages so problems show up where in the flight they happen, not just as a failed run in the log.
Flight Reliability: stage stat cards and the per-mission stage performance table

The headline cards

Stages flown, clean completion rate, trouble spots (stages with at least one abort or failure), and battery per km — cruise-leg battery burn weighted by flights, the number that tells you whether a mission is over-reaching the aircraft.

Where flights go wrong

When failures exist, this table names them: mission, stage, how often it flew, and how often it aborted or failed there. A mission that keeps failing on the same long leg into the gully is a route problem; failures spread across landings are an aircraft or site problem.

Stage performance

The full per-mission, per-stage table: flights, outcomes, average duration, distance and battery draw. Use it when re-planning a route — if one leg burns twice the battery of any other, that’s the leg to split or lower.
The default window here is 30 days — reliability patterns need more flights than a week provides.
