Boeing conducted a test flight Monday for one of its 787 Dreamliners, built for LOT Polish Airlines to check whether its redesigned lithium-ion batteries work. The flight was intended to test the batteries for the plane’s electrical system, including all backup systems and landing gear.
“Following the completion of the functional check flight, we will analyze the data from the flight and prepare for certification ground and flight demonstration in the coming days,” Birtel, Boeing spokesman, said. “The plan is to conduct one certification demonstration flight.”
Boeing is working to return the innovative 787 to the sky after the Federal Aviation Administration and other safety regulators worldwide grounded the fleet Jan. 16.
