At which threshold does the CMWS ECU hand off spatial coordinates to a JHCU?

The correct choice indicates that the CMWS (Countermeasure Warning System) ECU (Electronic Control Unit) hands off spatial coordinates to a JHCU (Joint Heads-Up Control Unit) at the cue threshold. This is a critical moment in the operational process as it signifies the point at which the system has gathered sufficient information to prompt a response or action. The cue represents a specific alert level where immediate attention is required, allowing the relevant systems and personnel to respond effectively to potential threats or changing situations.

In this context, understanding that the cue threshold specifically entails the transition from detection to actionable information helps highlight its significance. Other stages such as engagement, threshold, and detection may involve different processes or levels of readiness, but they do not specifically indicate the handoff of spatial coordinates, which occurs directly at the cue threshold. This distinction is essential for recognizing how operational systems integrate and act on data to ensure safety and efficiency.
