uncommanded
Done without instruction
Uncommanded describes action taken without being ordered or instructed—something done of one's own initiative rather than in response to a command.
The term appears most often in technical contexts, particularly aviation and engineering, where an uncommanded movement or response is one the system performs without operator input: The aircraft experienced uncommanded roll.
Such events are typically malfunctions.
In older or religious usage, uncommanded can simply mean voluntary or unbidden.
