Which term best describes an unplanned event of insufficient duration to adjust schedules?

• A. Foreseen Operational Condition
• B. Contingency
• C. Unforeseen Operational Circumstance
• D. Routine Delay

Answer: (C)

An unforeseen operational circumstance describes a disruption that is not anticipated and is too brief to allow a formal schedule rework or to activate a preplanned response. It signals a short, unexpected event that crews handle on the fly rather than following a prepared contingency, since there isn’t enough time to implement changes to the schedule.

Foreseen operational condition means something already anticipated and accounted for in the plan, so it isn’t unplanned. A contingency is a preplanned alternative designed to adjust for disruptions, which requires time to implement. A routine delay is a normal, expected delay within standard operating tolerances.
