When ARM schedules flights during periods of fleet downtime, which outcome best illustrates economy of scale?

• A. Short-term gains with no long-term planning
• B. Increased operational complexity
• C. Reduced maintenance downtime only
• D. Efficient allocation of resources to maximize output per resource unit and minimize idle resources

Answer: (D)

Economy of scale comes from making more output with the same or fewer inputs by using resources efficiently and avoiding idle capacity. Scheduling flights during fleet downtime aims to keep aircraft, crews, maintenance, and support resources busy, spreading fixed costs over more flight activity. When downtime is used to run additional flights, you maximize output per resource unit and minimize idle resources, which is the essence of achieving lower per-flight costs and greater overall efficiency.

That’s why the best fit describes efficient allocation of resources to maximize output per resource unit and minimize idle resources. It captures how you convert downtime into productive activity and reduce waste.

The other ideas don’t illustrate that idea as clearly. Short-term gains with no long-term planning misses the sustained efficiency focus of economies of scale. Increased operational complexity could come with scheduling, but it’s not the desired outcome. Reducing maintenance downtime alone is too narrow a benefit to fully reflect the broad resource efficiency? economies of scale aims for, across the whole operation.
