Boeing tells Sky News it is working with airline customers after three hi-tech 787s are hit by technical problems in three days.
Boeing's troubled 787 Dreamliner plane has suffered more technical problems.
Engine trouble grounded one plane in Japan on Wednesday, its operator said, marking the third consecutive day of problems for Boeing's next generation plane after months of difficulties.
While none of the most recent issues was thought to be serious, they spell more misery for Boeing, whose flagship plane has been beset with delays and failures, most seriously a battery problem that kept the global fleet out of the sky.
In the latest incident, one engine on a 787 would not start after 141 passengers had boarded the All Nippon Airways (ANA) plane in Yamaguchi prefecture in western Japan. The plane was bound for Tokyo.
A company spokeswoman said the pilot had called off the flight after being warned of the problem by cockpit instruments. The cause was being investigated.
The glitch came a day after a Singapore-bound Dreamliner, operated by ANA's rival Japan Airlines (JAL), had to turn back in mid-flight because of a problem with the anti-icing system.

On Monday, ANA had to cancel a Tokyo-bound flight while the plane was at an airport in Fukuoka, western Japan, after instruments showed the left engine was not functioning properly.
In a statement released to Sky News, Boeing said: "We are aware of these events and working closely with our customers.
"Cancellations and delays are not uncommon, the reliability of this plane is at or above any new airplane the industry has recently introduced."
The incidents come only weeks after JAL and ANA, the single biggest operator of 787s, put their full fleets of Dreamliners back into service following a four-month suspension over the battery problems.
A global grounding order was issued in January after lithium-ion batteries overheated on two different planes, with one of them catching fire while the aircraft was parked.
Boeing said in April that despite months of testing it did not know the root cause of the problems, but rolled out modifications - including reinforced battery boxes - it said would ensure the issue did not recur.
Since then, Dreamliners have experienced a series of minor teething problems, including a fault with an air pressure sensor.
 
Has anyone heard if the 787 is meeting the #s (range, fuel flows) that Boeing promised?

does that include the math for all the cancelled flights for the last how many months? I doubt it...
 
I talked to a united chief pilot who said united has been very happy so far with the performance, and the 787s are out performing. I believe he was talking specifically about the fuel burn

What cougar said. Prior to the battery fiasco ANA was reporting that it was actually bettering Boeings advertised fuel burn savings.
 
Saw a ANA one in SJC a week ago ... It was broken...

Looked good though...

I took off behind a UAL 787 in Denver the other day . . . Don't know how full it was, but at 90 degrees and 6000MSL, it was outclimbing our 73NG (we were around 142K). ;)
 
I was flying east bound over Pakistan yesterday at 370 and there was an Ethiopian flight opposite direction. About 100nm out the controller informs them that their mode C is indicating they are at FL362. He pauses and replies their altimeters indicate 360. ATC says well your mode C is showing 362. Do you want us to descend two hundred feet? No, just informing you what your mode Charlie is indicating. Ok we will try recycling... Ok, Good? Negative still indicating 3-6-2. This went on a bit and as they go closer, our TCAS showed them only 800 below. Finally about 20 miles out, the Ethiopian says "oh, we did not have our altimeters set to standard... fixed now and descending to 360"

A few seconds later a gorgeous new 787 passed beneath us.
