Data sources

Sprinkle stitches together 14 authoritative aviation data sources — civil registries, ICAO, OpenAIP, OurAirports, OpenFlights, Wikidata, GeoNames, and OpenSky. Every record carries provenance. Our editorial policy covers what we check and which text is written by AI.

Authoritative

Civil registries first. Where a regulator publishes the data, that's the source of truth.

Reconciled

Cross-source dedup with manufacturer fuzzy-match and Wikidata Q-IDs collapses 109k raw OEMs into ~36k canonical entries.

Provenance-traced

Every row carries a source_id and license posture. Public pages only show data we have the right to redistribute.
