Boeing completed a 787 certification demonstration flight on line number 86, a Boeing-owned production airplane built for LOT Polish Airlines. This flight marked the final certification test for the new Li-ion battery system, completing the testing required by the US Federal Aviation Administration (FAA). (Earlier post.)
The flight departed from Paine Field in Everett, Wash. at 10:39 a.m. Pacific with a crew of 11 onboard, including two representatives from the FAA. The airplane flew for 1 hour and 49 minutes, landing back at Paine Field at 12:28 p.m. Pacific.
The crew reported that the certification demonstration plan was straightforward and 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 gather and analyze the data and submit the required materials to the FAA. Boeing expects to deliver all of the materials to the FAA in the coming days.
