Which is faster 787 or 747?
Surprisingly however, the 747 is much faster than the 787. The 747 is Mach 0.005 faster than the 787, and travels further (if only briefly) than the 787. However, the 787 is also able to takeoff from a shorter runway, one that is only 9,300 feet compared to the 10,700 feet of the 747.
How much horsepower does a 787 have?
Boeing 787 Aircraft Overview The Boeing 787 will be powered by 55,000lb – 70,000lb thrust engines from General Electric and Rolls-Royce. GE is developing the new GEnX, Rolls-Royce the Trent 1000. Boeing claims a 20 per cent fuel burn advantage for the 787 over the 767 and an increased cruising speed of Mach 0.85.

Is the Boeing 787 9 Safe?
There is some speculation about rushing production of the 787–9, however nothing is yet to be confirmed, therefore, it is a considerably safe plane, and has no problems related to those of the 737 max 8.
Why is 787 so special?
The engineer. 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.
What is wrong with the Trent 1000 engines?
The Trent 1000 has caused some significant problems for the British engine manufacturer. Turbine blades have needed to be redesigned and replaced due to premature wear. At its peak, the issue saw 44 aircraft on the ground awaiting remedial work.
Is the Boeing 787-9 Safe?
Is 777 or 787 bigger?
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.
What’s the average speed of a Boeing 787?
It appears that’s a record for the Boeing 787-9 twin jet, which in the past has flown at speeds up to 776 mph. The ordinary cruising speed of a Dreamliner is 561 mph, with a maximum propulsion of 587 mph.
What’s the average landing speed of a B787-8?
The typical approach speed for a B787–8 landing at it’s maximum landing weight of 380,000lbs is 145kts (166mph)For the larger -9 it has an approach speed of 153kts (176mph) again at it’s max landing weight of 425,000lbs. Basically the heavier to aircraft the higher the speed required to make a safe…
Which is larger a Boeing 787 or a 747?
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. What is the top speed of a Boeing 787?
What’s the empty weight of a Boeing 787-9?
According to ILFC’s Steven Udvar-Hazy, the 787-9’s operating empty weight is around 14,000 lb (6,350 kg) overweight, which also could be an important obstacle for the future 787-10. It has a ‘stretched fuselage’ and will seat 250-290 passengers with a range of 8,000 to 8,500 nm (14,800 to 15,750 km).

What is the altitude and speed of a B787?
So for example if the aircraft weighs 500,000 lb, the pressure altitude will be 35,000 feet, Mach number will be 0.849, indicated airspeed will be 291 knots, the turbofan power ratio will be 73.9, or ~74% of available thrust, and the fuel flow per engine will be ~6,300 lb/hr (2,850 kg/hr).
