This first 787 aircraft is scheduled for delivery to United at the end of September.
The aircraft departed from the Boeing’ Paine Field in Everett, Washington on Sunday. On board Boeing pilots flew the 787 around the Seattle area for more than three hours as part of the planned tests of the aircraft’s controls and systems.
During the flight, crew members examined the on-board systems of the 787 at high and medium altitudes. They also checked backup and safety elements, including cabin pressurisation, avionics, navigation and communications systems.
Sunday’s flight was part of a series of work that Boeing performs after each 787 has been brought out of its paint hangar and before airlines take delivery of the aircraft. The work also includes fueling, systems tests, engine runs and taxi tests.
