On Wednesday afternoon, a Boeing 787-800 Dreamliner took off from Seattle on a test flight. Flight tracking apps show the Dreamliner followed a flight path over the United States that draws an outline of the Dreamliner.
It set the internet abuzz, likely one of the goals. But the Dreamliner was actually conducting a flight test of its new Rolls Royce engine "to prove to regulators that the airplane can safely operate on one engine for an extended period of time," according to Flightradar24, a flight-tracking app.

Those are some tight turns!
Boeing, You Better Have Carbon Offsets To Cover That Prank !
(If you don't I just happen to have some for sale.)
HAH! My first thought!
Al Gore will be apoplectic when he finds this out.
Maybe not turns but loop-de-loops?
I’d love to see the flight plan. (assuming they filed one)
It’s probably 12 pages long.
Not really when you consider the scale of the map behind it.......................
I don’t think they actually flew that course.
It would run out of fuel before it got to the end................
Do you supppose the pilot needed to be reminded to turn into the engine on those tight turns (being on one engine), or would it have really ever mattered with the power of those engines.
The inference of the article was that the flight was to demonstrate the performance of the aircraft flying on a single engine.
Which begs the question, probably known to ferry pilots faced with a long flight. I used to argue with my maintenance officer that I could extend the range and ferry distance of a CH-47, if we but just shut down one engine, fly at lower airspeed, yet extend our distance and of course time enroute. I was told I could not do it, as it was en emergency condition. I argued back that I must have been in an emergency every time I flew a single engine Huey.
With one engine out, only half the fuel is being consumed. Adjust for some lack of performance and the range should be increased.
Lol.
Now that would just be showing off :)
It works for cars, it should work for aircraft......................
My old Delta 88 car ran on 7 of 8 cylinders for a while....
With one engine off, wouldn’t the other be driving both rotors? I can’t imagine that would be very fuel efficient if the engine is doing a lot more work than it was designed for.
So you are saying this is fake?
The 787-900 has a range from 8000 to 8500 miles depending on load for in this in-flight testing mission was done with a very light load. They finsihed this with plenty of fuel left over.
A 747 can fly on one of its four engines..if the weight is not extreme..and of course there would be no go-around at landing.
No, only one engine would be pushing. Pillows compensate by adjusting the surface controls.
Pillows?! Damn! Meant pilots.
