Description PBN aims to ensure global standardisation of RNAV and RNP specifications and to limit the proliferation of navigation specifications in use world-wide. It is a new concept based on the use of Area Navigation (RNAV) systems. Significantly, it is a move from a limited statement of required performance accuracy to the following: The ICAO PBN Manual (Doc 9613) definition is: Area

Performance-based Navigation (PBN), in simple terms, redefines the aircraft's required navigation capability from sensor (equipment) based to performance based. The foundation for Performance Based Navigation is area navigation or RNAV. RNAV is a method of navigation which permits aircraft operation on any desired flight path

https://www.icao.int/safety/pbn/pages/overview.aspx
Introduction. Performance-based Navigation (PBN) defines performance requirements for aircraft navigating on an ATS route, terminal procedure or in a designated airspace. It is ICAO's effort and objective to redefine the regional differences of various Area Navigation (RNAV) and Required Navigation Performance (RNP) specifications into a globally harmonized set of PBN applications.

Performance based navigation (PBN), has already been implemented in some countries and in some it is about to be. It may be required in specific airspace and at certain airports depending on the situation. The challenge, especially for some small operators and/or flight schools is to understand what they have to do about PBN and its associated

What is Performance Based Navigation (PBN)? So let's zoom out and look at what PBN actually is. We'll cut it all down to just 1 sentence: PBN is area navigation (RNAV) based on specific performance requirements for aircraft flying on a route or approach, or inside controlled airspace. So basically, to keep things simple:

RNAV enables aircraft to fly on any desired flight path within the coverage of ground or space based navigation aids, within the limits of the capability of the self-contained systems, or a combination of both capabilities. RNP is RNAV with the addition of onboard performance monitoring and alerting capability.

We propose UAD, a method for vision-based end-to-end autonomous driving (E2EAD), achieving the best open-loop evaluation performance in nuScenes, meanwhile showing robust closed-loop driving quality in CARLA.

Benchmarking vision-based driving policies is challenging. On one hand, open-loop evaluation with real data is easy, but these results do not reflect closed-loop performance. On the other, closed-loop evaluation is possible in simulation, but is hard to scale due to its significant computational demands. Further, the simulators available today exhibit a large domain gap to real data. This has
