Trees are computed locally in your browser from the same X-Plane telemetry the PFD shows (ASCE coach engine, ported to JS). With X-Plane Data Output index 37 (engine RPM) enabled, the engine RPM/MP gates now resolve from real data at high confidence; without it they fall back to the “sensor gap → assumed OK, low confidence” path. Slip/skid (TC ball), visibility (IMC) and MSA references are still ungated sensor gaps.
Consequence Model · how the risk is estimated
Live gate calculations for the selected tree. Each meter plots the measured value
against the caution / danger thresholds the engine uses to estimate risk — the white needle is
where this frame sits, and the strip above shows how all four trees route into one consequence.
