Fuel efficiency: 20% better than previous aircraft, achieved through engine choice and lightweight composite materials
The Boeing 787 Dreamliner is 20% more fuel-efficient than previous aircraft such as the Boeing 767. This improvement is achieved through a combination of engine choice and lightweight composite materials.
Firstly, the Dreamliner's engines are more fuel-efficient than those of previous aircraft. Boeing selected two new engines to power the 787: the Rolls-Royce Trent 1000 and the General Electric GEnx. These engines contribute to approximately 40% of the aircraft's overall efficiency gain.
Secondly, the Dreamliner's airframe is composed of lightweight composite materials, which further enhances its fuel efficiency. This design choice reduces the overall weight of the aircraft, making it more fuel-efficient. The use of composite materials also improves the aircraft's aerodynamics, resulting in reduced drag and increased fuel efficiency.
In addition to these two main factors, the Dreamliner also incorporates other features that contribute to its fuel efficiency. These include aerodynamic improvements, advanced systems, and winglets. The combination of these factors results in a 20% improvement in fuel efficiency compared to previous-generation aircraft.
The fuel efficiency of the Dreamliner has significant benefits for airlines and the environment. Airlines can achieve millions of dollars in savings by choosing the Dreamliner over less fuel-efficient aircraft. Additionally, the Dreamliner's reduced fuel consumption leads to lower carbon dioxide emissions, contributing to the aviation industry's efforts to curb carbon emissions and reduce their environmental impact.

Cost analysis: Boeing 787 Dreamliner program cost $32 billion, with a cash loss of $45 million per plane
The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It is the first airliner with a mostly composite airframe, making it 20% more fuel-efficient than its predecessor, the Boeing 767. This fuel efficiency is also achieved through more aerodynamic shapes, winglets, and advanced computer systems.
The 787 Dreamliner program has reportedly cost Boeing $32 billion, with a cash loss of $45 million per plane. This massive investment means that profitability for the plane is not expected until the 2020s, if at all. Boeing expects to break even on the program after delivering 1,100 to 2,000 aircraft, with some analysts projecting that the company will never make a profit on the program. The high cost of the program is attributed to development expenses, which totaled $15 billion, and manufacturing costs for the jets already built.
In 2013, the cost of producing a 787 exceeded the purchase price, and Boeing lost $30 million per 787 delivered in the first quarter of 2015. Boeing's accounting method books sales immediately and distributes estimated production costs over ten years for the 1,300 aircraft it expects to deliver during that time. By 2014, Boeing planned to improve financial returns by reorganizing the production line, renegotiating contracts, and increasing the 787 production rate.
Despite the high costs associated with the 787 Dreamliner program, operators of the aircraft have reported significant fuel savings compared to the 767. For example, Rolls-Royce-powered ANA aircraft were burning around 21% less fuel than the replaced 767-300ER on international flights. Other 787 operators have reported similar fuel savings, ranging from 20 to 22% compared to the 767-300ER.

Fuel burn: Rolls-Royce-powered ANA aircraft burned 21% less fuel than the 767-300ER on international flights
The Boeing 787 Dreamliner is an American wide-body airliner that was designed with a focus on efficiency. It is the first airliner with a composite airframe, which, along with more fuel-efficient engines, winglets, and advanced computer systems, makes it 20% more fuel-efficient than its predecessor, the Boeing 767.
The Rolls-Royce-powered ANA aircraft burned 21% less fuel than the 767-300ER on international flights, exceeding the expected 20% fuel burn reduction. This efficiency gain is significant, as the 787-8 covers 6% more distance and flies 6% faster than the 767-300ER. On domestic routes, the Rolls-Royce-powered ANA aircraft achieved a fuel burn reduction of 15-20%.
The fuel efficiency of the 787 Dreamliner has a notable impact on operating costs. For example, United Airlines' 787s achieved a 6% lower operating cost per seat compared to the Airbus A330. Additionally, the Dreamliner's efficiency can offset higher fuel prices, as seen in the case of Level, where the lower cost of ownership of their A330-200s outweighed the higher fuel burn on a Barcelona-Los Angeles flight.
The Boeing 787 Dreamliner's fuel efficiency also contributes to emission savings. With a composite airframe, the Dreamliner achieves a 20% reduction in emissions compared to conventional aluminium airliners. This environmental advantage, coupled with its efficiency and performance, makes the Dreamliner a preferred choice for many airlines.
While the 787 Dreamliner has achieved impressive fuel burn reductions, it's important to note that actual fuel consumption can vary based on various factors such as passenger load, cargo weight, and headwinds. Additionally, the efficiency gains might be influenced by factors such as differing passenger counts between aircraft.
