Failure, defect or system degradation?

Three terms with different meanings.

Reviewed 2026-10-01 · FSHangar App (Windows) 1.4.2

Term	Meaning in this guide
Defect	A technical problem represented in the persistent aircraft record.
Simulator failure	A failure mechanism exposed by the aircraft add-on and activated through a supported integration.
System degradation	A system configuration change that reduces capability, without claiming access to a genuine add-on failure mechanism.

Why the distinction matters

Writing a documented system switch can change how an aircraft behaves without activating its internal failure engine. The Synaptic A220 evaluation confirmed this distinction and recommends a separate degradation provider.

What users should expect

Consult the aircraft capability page. A working telemetry connection does not guarantee failure injection, and an available degradation does not establish native failure support.

Recovery

A maintenance result in the cloud and restoration of an add-on system state are distinct operations. If the visible condition remains, inspect the integration status and report the observed behavior.
