AVIONICS · TRANSPARENT ESTIMATOR

Useful now.
Still chasing the true number.

NRW does not use arbitrary placeholders. When direct site-specific evidence is missing, a qualified estimator may keep the analytical model useful while the evidence team continues pursuing the factual value.

CURRENT ANALYTICAL INPUT
NO QUALIFIED ESTIMATE
No MODELED* value is bound to this instrument yet.

ANALYTICAL STATE · UNKNOWN

No filler value is substituted. A MODELED* number appears here only after comparator admission, formula, assumptions, uncertainty and sensitivity gates pass.

SHOW THE MATH

Every estimate gets a calculation receipt.

Verified project factsDocumented site/project inputs retain their original evidence classes and source paths.
Comparator cohortOnly admitted comparators with compatible period, geography, technology/context, metric and system boundary.
FormulaVersioned deterministic calculation from the NRW formula registry.
AssumptionsVisible. Never silently promoted to measured facts.
UncertaintyPrefer a defensible range over a falsely precise point value.
SensitivityShows which unresolved inputs materially move the answer.
