Depending on the purpous of the plane, the 787 is more efficient yes, but it can carry less passengers, and less cargo, then the 747.
On October 15, 2008 American Airlines announced that it entered into a purchase agreement with Boeing. Under this agreement, American intends to acquire an initial 42 Boeing 787-9 Dreamliners with the right to purchase up to 58 additional 787s.
The number 787 is bigger than the number 747. However if your asking about the Boeing Aircraft then the Boeing 747 is bigger than the Boeing 787.
Both, the Boeing 777 and the Boeing 787 have extremely long range than any other airplanes. The Boeing 777 is very old and it been around much longer than the Boeing 787. The Boeing 777 can also carry more passengers than the Boeing 787 but the Boeing 787 is lighter, can take off faster and easier, can travel faster and has more longer range than the Boeing 777. The Boeing 777 is heavier than the Boeing 787. Size does not even matter but the altitude and the range! Top speed of the Boeing 777: 567 miles per hour Top speed of the Boeing 787: 677 miles per hour Maximum cruising altitude of the Boeing 777: 43, 400 ft Maximum cruising altitude of the Boeing 787: 45, 200 ft
The A350 and the 787 are not really in direct competition, only the smallest A350 (A350-800) competes with the largest 787 (787-9). So I shall compare these two aircraft. It must be remembered that the A350 is actually in competition with the 777 and that the larger variants of the A350 will have better statistics than the stats shown below. Passengers (maximum): A350-800: 440 787-9: 290 Range: A350-800: 8,500 nmi 787-9: 8500nmi MTOW: A350-800: 259t 787-9: 251t MLW: A350-800: 193t 787-9: 193t Cruise (Mach): A350-800: 0.85 787-9: 0.85 Maximum (Mach): A350-800: 0.89 787-9: 0.89 Service Ceiling: A350-800: 43,100ft 787-9: 43,000ft Engines: A350-800: RR Trent XWB 787-9: GEnx or RR Trent 1000 Maximum Thrust: A350-800: 79,000lbf 787-9: 71,000lbf Cost ($millions): A350-800: 245.5 787-9: 200 As this comparison shows, the two are very equally matched, the only differences being cost and seats but these two cancel each other out. Sales cannot be compared yet as the 787-9 is already available whereas the A350 isn't. As I have previously said, the A350 and 787 are not in direct competition, with the 787 being a large variant of the family and the A350 being a small variant of the family. To summarise, the 787-9 is a big version of a smaller plane with smaller engines whereas the A350-800 is a condensed version of a large airliner. This means that the A350-800 is a more advanced airliner (e.g better and more powerful engines) than the 787-9 and if cost were no factor, the A350-800 would be the only choice for any airline.
To compare ( \frac{787}{1000} ) and ( \frac{7}{9} ), we can convert both fractions to have a common denominator or convert them to decimal form. ( \frac{787}{1000} = 0.787 ) and ( \frac{7}{9} \approx 0.777 ). Since ( 0.787 ) is greater than ( 0.777 ), ( \frac{787}{1000} ) is more than ( \frac{7}{9} ).
Since neither of these numbers has a decimal point, it can only be inferred that you are referring to integers - of which 788 is larger than 787.
Both models of the Boeing 787 (787-8 and 787-9) can fly at Mach 0.89
The 747 is much larger than the 787. The 747-400's maximum takeoff weight is 875,000 pounds. The 787- 800's maximum takeoff weight is 484,000 pounds.
Both models of the Boeing 787 (787-8 and 787-9) can fly at Mach 0.89
The 787 prices: 787-8 = US$185.2 Million. 787-9 = US$218.1 Million.
787 = 787.0
787-3: $146–151.5 million 787-8: $157–167 million 787-9: $189–200 million
