Which HLZ call indicates no enemy activity is observed above the AATFC threshold for tactical risk on the HLZ?

Which HLZ call indicates no enemy activity is observed above the AATFC threshold for tactical risk on the HLZ?

• A. Warm, or GREEN
• B. Clear, or BLUE
• C. Hot, or CHERRY
• D. Cold, or ICE

Answer: (D)

The key idea is that HLZ calls use color-coded risk levels to communicate threat relative to the AATFC threshold. Cold (or ICE) signals that no enemy activity has been observed above that threshold, meaning the HLZ is considered clear of threats at or above the defined risk level. This designation tells aircrews that it’s safe to proceed with landing under the current risk assessment. The other terms indicate higher or different levels of threat or conditions, so they do not match the scenario of zero activity above the threshold.
