The 787 ecoDemonstrator airplane makes a low-level pass over an acoustical array of microphones that measure aircraft noise during flight tests at Moses Lake in Eastern Washington in 2014. The airplane has been specially outfitted to flight-test 30 different environmental technologies. The 787 ecoDemonstrator flights will help evaluate such innovations as advanced navigation landing systems, enhanced aerodynamics, and airplane parts made from recycled materials such as carbon fiber. Also being tested are mobile devices that may help eliminate onboard paper to create a paperless flight deck. Boeing is the only major airplane manufacturer with a test plane dedicated exclusively to evaluating environmentally progressive technologies.
