How this database is built
EMPTYJET Aviation is a knowledge graph: facts are stored structurally first, and every public page is generated from the graph. No page is hand-maintained, and every fact carries its source, date and a confidence signal.

Conflict resolution
When sources disagree, the value from the higher-priority source wins (national registry & ICAO > manufacturer > licensed database > open data > encyclopedia > positions feed > AI extraction). Conflicting records are retained and flagged, never silently overwritten.
Estimates
Route nonstop capability, block times and runway suitability are computed estimates derived from published range/speed and airport runway data. They are labelled as estimates and are never booking figures.
Deferred layers
Individual tail-number records and live aircraft positions are deferred pending a source-licensing review — registry redistribution terms, ADS-B licensing, and owner privacy programs (FAA LADD / PIA). This test environment covers aircraft types, airports, routes and comparisons from public-domain and manufacturer-published data only.
