Which of the following is NOT one of the three evacuation types?

• A. Unwarranted
• B. Unplanned
• C. Planned
• D. Partial evacuation

Answer: (D)

In evacuations, the types are defined by how much planning and justification there is. A planned evacuation is pre-arranged and coordinated, with doors and slides deployed and passengers exiting in an orderly way. An unplanned evacuation happens when an emergency demands immediate egress without time for prior preparation, requiring rapid action. An unwarranted (unnecessary) evacuation is when people are evacuated without a justified need, creating avoidable risk and disruption. Partial evacuation isn’t considered a separate category in the standard three-type framework; it’s more like a partial action that can occur within a planned evacuation, but it doesn’t stand as its own type.
