TRUST / EVIDENCE

Data-source policy

A missing value is unknown—not zero, safe, supported, or complete.

Evidence labels

• Target: a design or planning requirement.
• Estimate: calculated or assumed and not field-validated for the exact configuration.
• Measured: observed in a named test or log.
• Verified: supported by an identified official source or validated evidence.

Source priority

Official manufacturer and FAA sources are authoritative for published specifications and regulatory descriptions. Reseller/comparison sources can assist discovery or current price context but do not override official technical documentation. Every precise operational result requires the fields needed by that model.

Configuration and price

Aircraft-only and package prices must remain distinct. Payload-dependent platforms require payload-specific assumptions; a modular airframe is not treated as carrying every sensor simultaneously. Quote-required, stale, out-of-stock, or region-specific pricing is identified and availability uncertainty lowers recommendation confidence.

Corrections

Report a source or catalog correction through the project issue channel. Do not include customer coordinates, flight logs, secrets, or private calibration data.
