In aviation, the term configuration refers to which of the following?

• A. The position of the landing gear and flaps.
• B. The alignment of the cabin seating.
• C. The status of cabin air conditioning.
• D. The trim setting for the elevator.

Answer: (A)

Configuration in aviation means the arrangement of the airframe’s external components that affect aerodynamics and performance. The landing gear position and the flap setting are the primary elements pilots adjust to define the airplane’s configuration because they directly change drag and lift, influencing takeoff, landing, and cruise behavior. When the gear is up and flaps are retracted, the airplane has a clean configuration with lower drag; when the gear is down or flaps are extended, drag increases and lift changes to support slower speeds for takeoff or landing. Interior aspects like cabin seating alignment or cabin air conditioning don’t alter the aerodynamics, and elevator trim is a control setting, not the exterior arrangement that defines configuration.
