If a track is flying below the high-altitude threshold (TMAT) and threatening an asset what ATC will the track receive

• A. 1-8
• B. 3-9
• C. 2-6
• D. 4-7

Answer: (C)

The concept being tested is how threat classification uses TMAT to assign an engagement priority. TMAT sets a high-altitude threshold; tracks below that threshold are considered low-altitude. When such a track is also threatening an asset, it receives an ATC that encodes both low altitude and asset threat, signaling immediate or prioritized engagement.

So, the ATC chosen corresponds to a low-altitude track that poses a direct threat to an asset, which is why that option is the best fit. The other codes represent different combinations of altitude relative to TMAT and threat to assets, and they don’t match both conditions at once.
