Which components are typically included in the assembly of an aircraft?

The assembly of an aircraft typically involves the integration of various major structural components that are essential for the aircraft's functionality, safety, and performance. The components listed in the first choice—fuselage, wings, empennage, landing gear, and control surfaces—are fundamental parts of the aircraft's physical structure and systems.

The fuselage serves as the main body of the aircraft, housing the crew, passengers, equipment, and providing the structural integrity of the aircraft. Wings are critical for generating lift, allowing the aircraft to fly. The empennage, which includes the tail section, is vital for stability and control during flight. The landing gear supports the aircraft's weight on the ground and allows for safe landings and takeoffs. Control surfaces like ailerons, elevators, and rudders provide the pilot with the ability to maneuver the aircraft effectively.

While the other options contain important components of an aircraft, they do not encompass the complete assembly framework typically considered in this context. Engines, cockpit instruments, and fuel systems are crucial for operation but are part of specific systems that support the aircraft's functionality. Similarly, the cabin interior and cargo holds focus on the interior layout rather than structural assembly, and winglets, propellers, and exhaust systems
