The new Boeing 777X will be the world's largest and most efficient twin-engine jet, unmatched in every aspect of performance. With new breakthroughs in aerodynamics and engines, the 777X will deliver 10 percent lower fuel use and emissions and 10 percent lower operating costs than the competition.
The 787 beats the 777-300 in range, but the smaller, lighter 777-200s and special extended-range versions of the 777 (777-300ER and 777-200LR) can fly circles around the Dreamliner.
Frankfurt, Germany (CNN Business) Boeing got another dose of bad news, as it announced Tuesday that its 777X plane, which is still under development, did not pass a safety test. No one was injured in the test, which took place Friday. A person familiar with the test said one of the doors came off the plane.
The A380 has 76 lie-flat seats with 48 inches of legroom in seat mode and is 18.5 inches wide (0.5 inches wider than economy). ... The Boeing 777, on the other hand, has 60 inches of pitch in seat mode (and angled-flat mode) and is 20.5 inches wide.
The Boeing 777 is designed to fly for at least 3 hours on one engine for a distance up to 1320 nautical miles or 2110 kilometers. That is further than from New York to Havana in Cuba. Pilots have been checked every 6 months in even more adverse emergency conditions than just a simple engine failure
