![]() ![]() The average incident rate per year since it entered service for the 787 is 0.5, whereas for the 777, it stands at 1.25. However, it’s important to note that the Boeing 787 only entered service in 2009, while the Boeing 777 has been operational since 1995, and inevitably this will account for some of the difference between these statistics. Remarkably, none of these occurrences led to any fatalities, and the aircraft in question sustained no hull losses. In contrast, up until March 2023, the Boeing 787 had been associated with seven incidents and accidents. Tragically, these events have resulted in a total of 541 fatalities. Among these, there were a total of eight hull losses, consisting of five incidents during flight and three that occurred on the ground, including three hijackings. Nevertheless, as of August 2022, the Boeing 777 had been involved in 31 aviation accidents and incidents. These aircraft are equipped with the latest safety systems, including advanced avionics, redundant control systems and enhanced monitoring capabilities. Jarek Kilian / Shutterstock Safety considerationsīoth the Boeing 777 and the Boeing 787 adhere to stringent safety standards set by aviation authorities worldwide. Furthermore, it enables numerous airlines to provide lower fares for long-haul routes. While it might not appear significant, over the duration of an extended flight this seemingly small difference can accumulate into substantial savings. ![]() ![]() This means that the Boeing 787-10 saves 0.63 liters of fuel per 100 kilometers flown per seat, when compared to the Boeing 777-300ER. In comparison, the Boeing 787-10 achieves a more efficient performance, consuming 2.27 L/100 km of fuel. On long-haul flights, the Boeing 777-300ER demonstrates a fuel consumption rate of 2.9 L/100 km per seat. In contrast, the 787 demonstrates a notably improved performance, with fuel consumption typically falling within the range of 4,900 to 5,600 liters per hour. The Boeing 787 is generally considered more fuel-efficient than the Boeing 777, due to its lightweight composite materials and aerodynamics.Īccording to information from All I Know About Aviation, the fuel consumption of the 777 series ranges from 6,080 to 7,500 liters per hour, with variations according to the specific variant. Nguyen / ShutterstockĪs such, we can conclude that the Boeing 777, specifically one with the GE90 engine, possesses a significantly higher thrust capability compared to the engines used in the Boeing 787. In comparison, both General Electric and Rolls-Royce engines used in the 787 provide a thrust of around 76,000 lbf. The GE90, utilized in the Boeing 777, is a powerhouse capable of producing a thrust of 110,000 to 115,300 pounds-force (lbf). Jordan Tan / ShutterstockĪ notable difference lies in the thrust these engines can generate. In contrast, the Dreamliner 787 is powered by either the General Electric GEnx or the Rolls-Royce Trent 1000 engines. These include the Pratt & Whitney PW4000, the Rolls-Royce Trent 800, and the General Electric GE90 engines. The Boeing 777 aircraft employs a range of engines based on its specific variant. Note: Specifications can vary based on airline configuration and model. On the 777, the maximum speed is typically Mach 0.89, whereas on the 787, it’s Mach 0.90. However, it’s worth noting that the 787 holds a slight speed advantage over the 777. ![]() Specificationįor an airline seeking new aircraft with an extended operational range to cover longer distances without the need for frequent refueling or en-route landings, opting for the 777 model would generally be advisable. The table below provides an overview of the technical specifications for each variant of the Boeing 777 and 787 series, allowing for easy comparison of their dimensions, capacity, range and speed. ![]()
