Which communication term indicates that the aircrew must only maintain situation awareness when in formation?

The term "Judy" is used in military aviation to signify that an aircrew is maintaining situational awareness and is able to execute commands without being given further detailed instructions. In this context, while in formation, aircrew members utilize their awareness of the situation to perform maneuvers that require a level of coordination and understanding of their surroundings.

This term allows the squadron to proceed with actions based on the understanding of the current tactical environment rather than needing step-by-step guidance. "Judging" situational awareness is critical in formation flying, as it improves efficiency and safety, allowing pilots to anticipate and react appropriately to movements and instructions from others in the formation.

On the other hand, the other terms do not carry the same implications for situational awareness in formation flying. For example, "Fox 3" refers to the launch of an active radar-guided missile, which is unrelated to the requirements for maintaining situational awareness. Similarly, "Pump" and "Close" have their specific contexts and meanings in communication, but do not denote a focus solely on maintaining situational awareness in a formation flying scenario.
