Definition of EcoDemonstrator
The ecoDemonstrator Program is a Boeing flight test research program, which has used a series of specially modified aircraft to develop and test aviation technologies designed to improve fuel economy and reduce the noise and ecological footprint of airliners.
Starting in 2012, several aircraft have tested a total of over 250 technologies as of 2024; half remain in further development, but nearly a third have been implemented commercially, such as iPad apps for pilot real-time information to reduce fuel use and emissions; custom approach paths to reduce community noise; and cameras for ground navigation and collision avoidance.
Boeing's named airliner technology programs started in 2001 with the Quiet Technology Demonstrator, and have continued, through the ecoDemonstrator, to the ecoDemonstrator Explorer program announced in 2023.
