Within PBN there are two main categories of navigation methods or specifications: area navigation (RNAV) and required navigation performance (RNP). In this context, the term RNAV x means a specific navigation specification with a specified lateral accuracy value.

2024年12月20日 · PBN代表了从依赖传统地基导航设备（例如，VOR/DME， 要求导航精度值的一半即海里以内）。 但各类运行也明确了可. 以支持其运行的特定导航传感器和设备的种类。 位置之间的偏差程度。 对于各类PBN运行，至少在95%的总飞行时间内， 示）之内。 由于侧向总系统误差（）等于导航定位精度误差（） （ANP/EPE）值应保持在1倍RNAV/RNP值以内。 发出告警的能力。 对于RNP运行，在95%的总时间内侧向总系统误差. 员提供完好性告警。 该类告警可 …

Using first-principles calculations combined with the unified theory of thermal transport, we found that penta-PbN 8 possesses a low lattice thermal conductivity at room temperature with the value of 4.61 (5.23) W m −1 K −1 along the x (y)-direction and a dominant contribution of 3.32 (3.84) W m −1 K −1 from the corresponding phonon ...

PBN represents a fundamental shift from sensor-based to performance-based navigation and offers a number of advantages over the sensor-specific method of developing airspace and obstacle clearance criteria, i.e.:

1. PLACE AND DURATION 1.1 The Eighth meeting of the Performance Based Navigation Sub-Group (PBN SG/8) was successfully held in Doha, Qatar, from 12 to 13 December 2023.

Performance-based navigation (PBN) The PBN concept specifies that aircraft RNAV system performance requirements be defined in terms of the accuracy, integrity, availability, continuity and functionality, which are needed for the proposed operations in the context of a particular airspace concept.

基于性能导航（PBN）规定了航空器在指定区域内或者沿ATS航路、仪表程序飞行的系统性能要求，包括导航的精度、完整性、可用性和所需功能。 PBN规定的RNAV系统沿ATS航路运行的精度要求有RNAV5 (+/-5NM)、RNAV1/RNAV2 (+/-1NM)。

这年11月，我国在三亚飞行情报区实施了RNP10的洋区PBN航路，建设了4条越洋RNP航路，提高了南中国海北部空域的空中航班流量及飞行安全性，提高了航班运行的灵活性，航班延误现象大幅减少，便捷了途经该空域的相关国际航线城市的空中交通联系。

Based on the Denon DP80, the PBN-DP8 boasts a motor that is larger, more powerful and more advanced than is used in any other turntable. With over-all heftier specs and a larger, dual-layer platter, it gives outstanding stability and unparalleled performance.

The M-PBN8 Steel Base Plate is used to connect positioners with bottom-surface mounting holes to support structures that are inaccessible from below, such as breadboards and optical tables. An array of tapped and countersunk clearance holes provides compatibility with UMR8, MVN80, and UTR80 Series Stages.
