What alert level involves an actual aircraft accident?

• A. Alert I
• B. Alert II
• C. Alert III
• D. Alert IV

Answer: (C)

The level used when there is an actual aircraft accident is the one that triggers immediate, coordinated response and full mobilization of resources. An actual crash means a confirmed, significant event with potential injuries, damage, and disruption, so it requires activating the emergency operations center, coordinating with outside agencies, and bringing in multiple teams (rescue, investigation, security, communications). The other levels are for less severe or evolving situations—where there might be threats, uncertainties, or broader impacts but no confirmed crash—so they don’t demand the same immediate, full-scale response.
