Boeing has started final flight testing of the 787 Dreamliner

Boeing said Monday that it has started its “function & reliability” testing and extended operations demonstrations on the 787 Dreamliner — the final flight testing phase before certification.

“The team has created a solid plan for accomplishing the hours and test points required for F&R and ETOPS testing in support of delivery to our customer ANA in the August to September time period,” said Scott Fancher, vice president and general manager of the 787 program.

Function & reliability testing simulates various operations in a realistic airline-like flight environment. Extended operations demonstrations are for twin jets — flights that are more than 60 minutes away from a suitable landing field. During such tests, Boeing validates the airplane’s ability to safely divert for a variety of reasons, including long diversions with one engine shut down.

In addition to the testing for the 787 with Rolls-Royce engines, Boeing continues certification testing on 787s with General Electric engines.
