In late 2014, The Boeing ecoDemonstrator 787 began flight testing more than 25 new technologies aimed at improving aviation's environmental performance through every phase of flight. The Boeing ecoDemonstrator Program accelerated the testing, refinement and use of new technologies and methods that can improve efficiency and reduce noise. This new round of testing, using 787 Dreamliner ZA004, evaluated software and connectivity technologies related to operational efficiency; remote sensors to reduce wiring; aerodynamic and flight control improvements for greater fuel efficiency, and icephobic wing coatings to reduce ice accumulation.
