Which agency is responsible for developing technical standards for the NextGen air traffic control system?

The correct response is the Federal Aviation Administration (FAA), as it plays a central role in the development and implementation of the NextGen air traffic control system. NextGen is a comprehensive modernization of the entire national airspace system in the United States, designed to increase safety, efficiency, and environmental sustainability.

The FAA is tasked with establishing technical standards, regulations, and procedures for air traffic operations, which includes the development and deployment of Advanced technologies in the NextGen system. As the regulatory body for civil aviation, the FAA ensures that all innovations in air traffic management align with national safety and operational requirements.

In contrast, other organizations like the National Transportation Safety Board (NTSB) primarily focus on investigating transportation accidents and safety recommendations. The National Aeronautics and Space Administration (NASA) has a role in research and development related to aeronautics but does not set the technical standards for air traffic control systems. The Department of Transportation (DOT) oversees various aspects of transportation policy but delegates specific regulatory responsibilities, including those for aviation standards, to the FAA.
