Final answer:
Trajectory-based operations (TBO) in NextGen is an advanced air traffic management approach that allows for more efficient and precise flight paths using GPS technology, advanced avionics, and computer algorithms.
Step-by-step explanation:
Trajectory-based operations (TBO) in NextGen refer to a modernized method of managing air traffic that uses precise navigation techniques to manage aircraft flight paths. Unlike traditional air traffic management, which relies on radar-based vectoring and altitude assignments, TBO enables more efficient routes by allowing aircraft to fly optimized paths that are pre-calculated and can be modified in real-time to accommodate for various factors such as weather, traffic, and airspace constraints. This approach aims to enhance efficiency, capacity, safety, and environmental sustainability in the National Airspace System.
The key components of TBO involve utilizing Global Positioning System (GPS) technology, advanced avionics, and sophisticated computer algorithms to create more direct and efficient flight paths. The integration of TBO within NextGen signifies a shift from the ground-based navigation systems of the past to a satellite-based system that offers improved accuracy and reliability for the management of flight trajectories.
