Evidence & credibility

A simulation platform is only as useful as the evidence trail it produces. UAVSimNet is built so that every claim in a run report is traceable back to a named source, a confidence class, and an approval event.

Run report cover. Identifiers, parameter values, and reviewer names redacted; structure preserved.
Validated-vs-provisional registry

Every parameter is tagged at registration time with a confidence class — reviewed, provisional, or imported — and every downstream record preserves that tag unchanged. A run composed entirely of provisional inputs cannot accidentally masquerade as validated.

Citation-first

Parameters with sources outside our own engineering ship with the reference embedded (literature, a published airframe spec, or a customer-supplied document). The reference follows the parameter into every run report that uses it.

Bit-exact replay (kinematic)

For kinematic runs, the engine is fully deterministic — same inputs, same outputs, byte-for-byte. A replay is used in regression testing so a new release cannot silently change a trajectory.

Independently verified JSBSim

Flight-dynamics backend uses JSBSim, an independently maintained 6-DoF library with decades of aerospace provenance. We do not modify the core solver; we stitch airframe, environment, and control integrations around it.

Reviewer chain

Analysts submit; reviewers approve, request changes with notes, or reject. Only approved runs can be promoted to golden references. Every state transition is audited with user id and timestamp.

Immutable run snapshot

At submit-time, every parameter that contributed to the run is frozen into an immutable snapshot on the run record. The snapshot survives later edits to the underlying library blocks — what ran was what ran.
