How fuel efficient is the Boeing 787?

A Boeing 787-9 burns about 5400 litres of fuel per hour. At a cruising speed of 900km/h, that equates to 600 litres/100km.

Why is 787 so fuel efficient?

In flight deck, a head-up display increases the pilots’ situational awareness and specially designed surfaces on the wings make the aircraft more fuel efficient. With greater use of electrical systems, there is less use of the hydraulics systems, reducing weight and thus increasing fuel efficiency.

How efficient is the Boeing 787?

On domestic routes, the saving is 15-20%, which meets expectations, say ANA officials. Wikipedia’s B787 article states that: According to data from launch customer All Nippon Airways, the 787 surpassed the promised 20% fuel burn reduction compared to that of the Boeing 767.

How much more fuel efficient is the Boeing 787?

Newer aircraft like the Boeing 787 Dreamliner, Airbus A350 and Bombardier CSeries, are 20% more fuel efficient per passenger kilometre than previous generation aircraft.

What is the most fuel efficient airplane?

Otto Aviation says on its website that 31 successful test flights have so far been performed, with aerodynamic efficiency proven in 2019, bolstering its declaration that “the Celera 500L is the most fuel-efficient, commercially viable aircraft in existence.”

Why is 787 so special?

One of the most unique things about the 787 is its raked wingtip, where the wing sweeps upwards at the end. It’s designed to give the aircraft more fuel efficiency and allow it to climb in a better way. It’s probably the first time we’ve seen this in commercial service.

Is Boeing 777 or 787 better?

The Boeing 777 series is generally larger than the 787 and thus can carry more passengers. The 787-10 has a higher capacity than the smaller 777-200 series. However, it falls short of the larger 777-300 models by 66 passengers in a typical two-class configuration.

Which engine is the most fuel efficient?

Diesel engines generally achieve greater fuel efficiency than petrol (gasoline) engines. Passenger car diesel engines have energy efficiency of up to 41% but more typically 30%, and petrol engines of up to 37.3%, but more typically 20%.

How much fuel does a 747 burn on takeoff?

A typical Boeing 747-400 passenger jet burns between 5,633 and 5,772 pounds of jet fuel on takeoff. For Boeing 747-400 freighters, the amount increases to between 6,389 and 6,589 pounds. The 747-8 passenger plane can carry up to 422,000 pounds of jet fuel, or 63,034 gallons.

Are planes more efficient than cars?

Overall, the combination of better technology and more crowded planes has ratcheted down the energy intensity of air travel by an impressive 74 percent, to only 2,691 BTUs per passenger-mile. That’s 57 percent better than your average automobile.

How far can the 787-9 Fly?

The stretched 787-9, 206 ft (63 m) long, can fly 7,635 nmi (14,140 km) with 290 passengers; it entered service on August 7, 2014, with ANA. The further stretched 787-10, 224 ft (68 m) long, seating 330 over 6,430 nmi (11,910 km), entered service with Singapore Airlines on April 3, 2018.

Why is the 787 called the Dreamliner?

Boeing cancelled the Sonic Cruiser and replaced it in January 2003 with the “7E7,” which was the code name for the 787 at the time. In July 2003, Boeing decided to call the new plane the “Dreamliner.” … It did this by using composite to build most of the plane instead of aluminum, which made the plane lighter.

How much does a gallon of jet fuel cost?

As of Monday afternoon, Jet-A is selling to corporate jets for an average of $5.21 per gallon. (Fuel is usually more expensive on the coasts and cheaper in the Midwest.) Because the cost of Jet-A closely tracks the price of a barrel of oil, fuel costs for private jets have quadrupled since 2000.

Do planes fly slower to save fuel?

FLYING SLOWER

One of the biggest fuel savings has come from flying aircraft more slowly. From the perspective of fuel consumption, there is an optimal cruising speed for each aircraft based on altitude. … Historically, commercial aircraft have flown on average about 8 percent faster than their optimal cruising speed.

How much does it cost to fuel a 747?

Seats to fill

A 747 can seat 380 to 560 people, depending on how an airline sets it up. A full one is a moneymaker. But an airline that can’t fill all the seats has to spread the cost of 63,000 gallons of jet fuel — roughly $200,000 — among fewer passengers. The jets also are too big for most markets.

What fuel do airplanes use?

Jet fuel (Jet A-1 type aviation fuel, also called JP-1A) is used globally in the turbine engines (jet engines, turboprops) in civil aviation. This is a carefully refined, light petroleum. The fuel type is kerosene. Jet A-1 has a flash point higher than 38°C and a freezing point of -47°C.
