Boeing 777 Case Study

Digital design. 777 is the first jetliner designed completely by computers. Historically, Boeing had two designing methods, full-size models namely mock-ups and paper drawings. Paper drawings were 2-dimensional, hence insufficient to account for the complex construction of the 3-dimensional. The problems of incompatibilities of parts and components were pervasive and costly. On the other hand, the engineers are required to redesign and realign all the incompatible or overlapped parts so as to solve the problems, thus increased the engineers’ workloads and reduced the work efficiency. The digital design system had the distinctive advantages as follows.
i. 100% visualization. The digital design system provided the engineers with a full-scale visualization, allowed to rotate, zoom, and interrogate the parts geometrically, in order to spotlight the interferences. ii. Ease inspection. Digital design system assigned a numerical value to each drawing on the screen, thereby helped engineers to locate and merge the

Boeing 777 was the first commercial transport manufactured by Boeing which employed a Fly-By-Wire (FBW) Primary Flight Controls System [2] to satisfy its airline consumers, and partly to challenge Airbus’ leadership in flight control technology, a position Airbus had held since it introduced the world’s first FBW aircraft, the A-320 in 1988. Different from the conventional primary flight controls system, which employs hydraulic actuators and controls valves controlled by cables that are driven by the pilot controls, FBW primary flight controls system removes the cable control, and rather the actuators are controlled electrically, not mechanically. The cores of the system are electronic computers, which convert electrical signals sent from position transducers attached to the pilot controls into commands that are transmitted to the actuators. The FBW flight controls system had the distinctive advantages as
