What does "aircraft reconfiguration" mean?

"Aircraft reconfiguration" refers specifically to the process of adjusting the interior setup of an aircraft to meet specific flight requirements. This often involves modifying seating arrangements, cargo space, or other interior arrangements to cater to the needs of a particular flight, such as accommodating more passengers, adjusting for special cargo, or preparing for different classes of service. Airlines and operators frequently carry out this important task to ensure that the aircraft is optimized for each mission or flight, improving both safety and comfort for passengers and efficiency for operations.

The other options represent activities that may occur in the aircraft operations context, but they do not accurately define "aircraft reconfiguration." Changing weight distribution is a critical consideration in flight safety but does not encompass the alteration of the interior layout of the aircraft itself. Refueling is essential for flights but pertains to operational readiness rather than interior changes. Cleaning the aircraft is a maintenance task focused on hygiene and presentation, not related to reconfiguring the space for flight.
