Philadelphia International Airport is at the forefront of a technological revolution that will lead to safer, more efficient air travel, writes AIA President and CEO Marion Blakey in an op-ed for the Philadelphia Inquirer. When the airport switches on its satellite-based flight tracking system in the next few days, controllers will be better able to monitor and sequence aircraft in the area -- a first step to reduced emissions, shorter flights and reduced delays. As the first major U.S. city with ADS-B technology, Philadelphia represents a "great foundation" for NextGen, Blakey writes. She urges policymakers to accelerate the program elsewhere in the country.
