As a founding member of the International Civil Aviation Organization (ICAO), the United States has partnered with countries around the world for 80 years to harmonize civil aviation regulations, standards, procedures, and organizations. This cooperation has built an aviation ecosystem where safe, reliable air transportation is commonplace. But as the industry evolves to accommodate new entrants, new technologies and increasing volumes of passenger and cargo traffic, simply maintaining this ecosystem is not enough. Continued investment in a well-connected, global aerospace system is critical.
