An analysis of 56 airports’ operational capacities has concluded that the FAA must “move forward aggressively” to implement the NextGen system or risk further delays at 27 major airports. The Future Airport Capacity Task (Fact) report also found that 15 metro areas will have to make use of smaller, regional airports, such as Teterboro Airport in New Jersey and Stewart International in New Windsor, N.Y., to avoid increasing congestion. The report stated that using NextGen will lead to “enhanced capabilities in the cockpit, better navigation and landing capabilities” and improved knowledge of weather and traffic conditions. The study also found that by implementing NextGen, 35 of the busiest airports will see “significant delay reduction.” In addition, the results of a similar study by Airports Council International found that airports will have to invest $87.4 billion over the next four years to improve runways, terminals and gates to avoid overcrowding and longer delays.
