Boeing: 777 Design Highlights (2024)

1. Designed for Efficiency
2. Computer-Aided Design Technology
3. 777 Technology Provides Exceptional Value

The advanced wing design of the 777 features a long span with increased thickness to dramatically improve airplane performance and reduce operating costs. Optimized for the greatest lift with the least drag, the advanced wing shape allows the 777 to climb quicker, cruise faster and higher, and consume less fuel during cruise. Flying at Mach 0.84—virtually the same speed as the 787 and 747-8—the 777 gives airlines the benefit of efficiency and speed.

Raked wingtips were added to improve overall aerodynamic efficiency, extending each wing by 2 meters (6.5 feet). The raked wingtips help reduce the required takeoff field length, increase climb performance, and reduce fuel burn.

Strategic use of composites and advanced alloys

Advanced alloys saved 1,450 kilograms (3,200 pounds) of structural weight on the 777. Selected for mechanical properties and for their light weight, the advanced alloys contribute to the remarkable dispatch reliability and maintenance economics of the 777.

Composite materials reduced 777 structural weight by 1,180 kilograms (2,600 pounds). Resistant to fatigue and corrosion, composite materials reduce maintenance time, saving airlines money and increasing airplane availability.

Digital technology aboard the award-winning 777 flight deck saves time and money

Thoroughly integrated displays, controls, and automation work together to enhance the pilot‐airplane interface while making flight deck procedures efficient.

Large flat‐panel displays present flight information in a readily accessible form, allowing pilots to quickly analyze flight parameters for safety, schedule, passenger comfort, and economics. Electronic checklists, which airlines can customize with airline‐specific information and procedures, teams the flight crew and airplane systems together, integrates the checklist with the flight deck systems, automatically checks off items, and serves as a reminder of required operations, when combined this saves valuable minutes which translates into dollars. Adding the electronic flight bag (EFB) significantly reduces the need for paper on the flight deck and uses airplane‐to‐ground connectivity to deliver more critical information to the appropriate departments. Documents, including charts, flight manuals, aircraft and pilot logbooks, and electronic airport qualification information is downloaded electronically. The electronic flight bag enhances flight operations and reduces recurring expenses. EFB class 3 provisions are provided as part of the basic airplane. The flight deck and flight management system provide ample provision for future enhancements, such as improvements to air traffic management systems.

The 777 flight deck won the Industrial Design Excellence Award from the Industrial Designers Society of America.
