Boeing 777-300ER completes extended operations flight testing

The Boeing 777-300ER passenger airplane recently completed its extended operations (ETOPS) certification tests, demonstrating the superior reliability of the airplane and its two general electric engines.

Two 777-300ER (extended range) airplanes made 38 flights totaling 267 flight hours during testing. The flights included various system checks and simulated malfunctions to ensure the airplane's systems work in the long-range environment.

During eight separate tests one of the 777- 300ER's two GE90-115B engines was turned off so the airplane flew on just one engine. The longest such test lasted for 6 h 29 min – the longest engine- out demonstration flight ever in support of ETOPS certification.
