What does it mean when aircrew are described as operating autonomously?

When aircrew are described as operating autonomously, it means they are functioning independently, without the need for ongoing command and control from a supervisory body or higher authority. This implies that they have the ability to make decisions and execute missions based on their own judgment or pre-established guidelines. Autonomous operation can be critical in situations where real-time communication is difficult or impossible, allowing crews to respond effectively to dynamic conditions without waiting for instructions.

In contrast, options that suggest following commands, being under direct supervision, or being grounded do not align with the concept of autonomy. These alternatives imply some level of external control or restrictions, which directly contradict the notion of autonomous operation.
