What initiative is designed to enhance the efficiency and security of air travel?

The Next Generation Air Transportation System (NextGen) is a comprehensive modernization initiative that aims to enhance the efficiency, safety, and security of air travel. By transitioning from the traditional ground-based air traffic control systems to a satellite-based system, NextGen facilitates improved communication, navigation, and surveillance capabilities. This evolution allows for more precise flight routing, optimizing airspace use and reducing flight delays, which in turn enhances the security of air travel through better management of aircraft trajectories.

NextGen also incorporates advanced technologies that bolster flight safety by providing real-time data to pilots and air traffic controllers. This technology enables proactive identification of potential hazards and the implementation of measures to mitigate risks, ultimately contributing to a more secure aviation environment.

The other initiatives listed, while important in their own right, focus on more specific aspects of aviation security or safety. They do not encompass the broader, system-wide enhancements in efficiency and security that NextGen aims to provide.
