Performance-Based Navigation (PBN)

Performance-based navigation specifies RNAV system  performance requirements for aircraft operating along an ATS  route, on an instrument approach procedure, or in airspace. Performance requirements are defined in terms of accuracy, integrity, continuity, availability and functionality needed for the  proposed operation in the context of a particular airspace concept. Performance requirements are identified in navigation specifications that also identify the navigation sensors and equipment that may be used to meet the performance requirement.
