Mechanisms¶
- Redundant Sensor or Channel Comparison
- The disagreement exceeds the voting threshold — set from the combined measurement uncertainty of the channels so that ordinary noise doesn't trip it — and the computer isolates the outlier, down-weights it, and alerts the crew, all while the aircraft flies on the two channels still in agreement.
This sourceUses a bank of Kalman filters and residual patterns to detect a sensor fault and isolate which sensor is faulty.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
