Final answer:
Performance-Based Navigation (PBN) requirements are based on performance requirements, ensuring navigation system meet specific operational standards.
Step-by-step explanation:
Under Performance-Based Navigation (PBN), the generic navigation requirements are defined based on performance requirements. These are associated with the capabilities of navigation systems rather than being dependent on the aircraft type and weight, the pilot's experience, or the geographic location. PBN standards are designed to ensure that aircraft navigation systems meet the performance levels necessary for the specified operations in terms of accuracy, integrity, availability, continuity, and functionality required in the navigation specification.
