Air Defense Principles, Systems, And Operations Practice Exam

What is CRAM DNES in air defense terminology?

Bubble whose size is determined by track quality, placed around friendly aircraft preventing the LPWS from engaging to prevent fratricide A radar mode used to detect stealth aircraft A communications protocol for coordination A surface-to-air missile type

Correct Answer:

Bubble whose size is determined by track quality, placed around friendly aircraft preventing the LPWS from engaging to prevent fratricide

Explanation:

CRAM DNES is a protective buffer around a friendly aircraft used to deconflict engagements and prevent fratricide in a layered air-defense environment. The size of this bubble is driven by track quality—the more confident the track, the smaller the bubble, allowing engagement of true threats outside; when track data is uncertain, the bubble grows to keep shooters from risking a friendly aircraft. It’s a safeguard mechanism, not a radar mode, a communications protocol, or a missile type.
