More environmentally friendly aircraft designs, particularly with regard to noise, was a Technology for a Quieter America (TQA) workshop hosted by the National Academy of Engineering (NAE) held in May 2017. This workshop titled Commercial Aviation: A New Era, centered on the importance of commercial aviation to the U.S. economy, and what it will take for the U.S. to maintain global leadership in the aviation sector, including a forward-looking topic on more environmentally friendly aircraft designs. A principal focus of the workshop was the necessary step-changes in aircraft engineering technology that must be addressed with the development and testing of flight demonstrators together with significantly increased funding of public-private partnerships. Government agencies which participated included NASA, the Federal Aviation Administration, and the Department of Housing and Urban Development (HUD). There was also substantial participation from the aviation industry, airports, airlines, non-government organizations and academia.
