Which term refers to irregular operations including delays, cancellations, diversions, and long tarmac delays?

• A. Irregular Operation
• B. Disruption Event
• C. Flight Irregularity
• D. Schedule Disruption

Answer: (A)

The term needed is the umbrella idea used in aviation to describe disruptions to normal flight operations—delays, cancellations, diversions, and long tarmac delays are all included under irregular operations (often called IROPs). This is the best answer because it is the standard, formal phrase that covers the full range of operational disruptions, not just a single type of issue. Other terms don’t carry the same official breadth. They might sound plausible but aren’t the recognized label for all irregular disruptions in airline operations, and they don’t imply the complete set of situations that operations and customer service teams handle under irregular operations. In practice, teams refer to IROPs to guide response actions like notifying customers, rebooking, and coordinating crews.
