Boeing completed a 787 certification demonstration flight Friday on line No. 86, a Boeing-owned production airplane built for LOT Polish Airlines.
The flight marks the final certification test for the new battery system, completing the testing required by the Federal Aviation Administration.
The flight departed from Paine Field in Everett, Wash. It flew for an hour and 49 minutes before landing back at Paine Field.
The crew reported that the flight was uneventful. The purpose of the flight was to demonstrate that the new battery system performs as intended during normal and non-normal flight conditions.
Boeing will now analyze the data and submit the required materials to the FAA in “the coming days,” Boeing said.
