What is the position on the MXU-835/P communication subsystem that is designated for listen-only functionality?

The correct position designated for listen-only functionality in the MXU-835/P communication subsystem is the second position. This functionality is crucial because it allows the user to hear communications without the ability to transmit, ensuring that critical information can be received while preventing any accidental transmissions. The listen-only capability is particularly important in environments where discretion is necessary, or when the focus needs to remain on receiving situational awareness rather than conversing.

The other positions are assigned functionalities that involve either other types of communication tasks or control settings that allow for both listening and transmitting. This differentiation is essential for aircrew operations, where managing communication channels appropriately can directly impact mission success and safety.
