What is A/C on Boeing 777? (Aircraft)

When it comes to modern aviation, the Boeing 777 is undoubtedly one of the most prominent and widely recognized aircraft. But what exactly do we mean when we refer to an “aircraft” on the Boeing 777? In the context of this incredible aircraft, the term “aircraft” or “A/C” refers to the entire body or structure of the plane, including all of its systems, components, and equipment.

The aircraft is designed to carry passengers, cargo, or both, and it serves as the platform for the remarkable aerodynamic capabilities that allow the Boeing 777 to take flight. Let’s take a closer look at some key aspects of the aircraft on the Boeing 777 to gain a deeper understanding of its complexity and engineering marvel.

The Structure of the Aircraft

The aircraft structure of the Boeing 777 is primarily composed of aluminum and composite materials. The fuselage, which extends from the nose to the tail and provides the main body of the aircraft, is a critical component. It is responsible for housing the passengers, crew, cargo, and all necessary systems, such as the electrical, hydraulic, and fuel systems.

Within the fuselage, there are multiple sub-sections that make up different areas of the aircraft, such as the cockpit, cabin, and cargo hold. These sections are designed to meet specific requirements for safety, comfort, and efficiency.

The Wings and Engines

The wings of the Boeing 777 provide the necessary lift to keep the aircraft in the sky. They are carefully designed to optimize aerodynamic efficiency, incorporating features such as winglets to reduce drag and improve fuel efficiency. The wings also house the fuel tanks, which store the large quantities of fuel required for long-haul flights.

Under the wings, the Boeing 777 is equipped with two powerful engines that are capable of propelling the aircraft through the air with incredible speed. The engines are typically positioned under the wings to take advantage of the undisturbed airflow, providing optimal performance and minimizing noise in the cabin.

The Landing Gear and Control Systems

The landing gear of the Boeing 777 consists of multiple wheels and struts that support the aircraft during takeoff, landing, and while on the ground. These systems are carefully designed to withstand the immense forces and weights involved, ensuring a smooth and controlled operation at all times.

The control systems of the Boeing 777 are responsible for maintaining stability and maneuverability during flight. These include the flight control surfaces, such as the ailerons, elevators, and rudder, which are used to control the roll, pitch, and yaw movements of the aircraft. Additionally, the aircraft is equipped with advanced avionics and autopilot systems that assist the pilots in navigation and control.


The aircraft on the Boeing 777 encompasses the entire structure, systems, and equipment that make up this remarkable flying machine. From the fuselage housing passengers and cargo to the wings providing lift and the engines propelling the aircraft forward, every component plays a crucial role in its safe and efficient operation. Understanding the intricacies of the aircraft on the Boeing 777 allows us to appreciate the immense engineering effort involved in creating such a marvel of modern aviation.
