* VOR: Very High Frequency Omni-Range. A ground-based electronic navigation aid transmitting very high frequency navigation signals, 360 degrees in azimuth, oriented from magnetic north. * DME: Distance Measuring Equipment. A transponder-based radio navigation technology that measures distance by timing the propagation delay of VHF or UHF radio signals. IRS: Inertial Reference System. Provides position information for use by an RNAV or FMS system providing either stand alone position input or to mix with radio position data. * Area Navigation is a method of navigation which permits aircraft operation on any desired flight path within the coverage of station-referenced navigation aids or within the limits of the capability of self-contained aids, or a combination of these.‘ 第一个问题：原本RNAV与RNP的概念及区别？ * TRNAV=Terminal RNAV 值为：RNAV1RNAV2 RNAV type B 值为：RNAV1 * 可以在图片上直接添加链接 * 区域导航(RNAV area navigation)。 RNAV是一种导航方式，它可以使航空器在导航信号覆盖范围之内，或在机载导航设备的能力限制之内，或二者的组合，沿任意期望的航径飞行。RNAV要求在95％的飞行时间内必须满足规定的精度。 所需导航性能（Required Navigation Performance）。 对在规定空域内运行所需要的导航性能精度的描述。RNP的类型根据航空器至少有95%的时间能够达到预计导航性能精度的数值来确定。 第二个问题：新的ＲＮＡＶ与ＲＮＰ的概念还有什么区别呢？ * The PBN Concept links the capabilities of the aircraft and associated operator requirements, laid down in a particular Navigation Specification, with the available Navigation Aid (NAVAID) Infrastructure to support the Navigation Application. * Global Navigation Satellite System * * * Notes: The numbers given in the table refer to the 95% accuracy requirements(NM) RNAV 5 is an en-route navigation specification which may be used for the initial part of the STAR outside 30NM and above MSA RNP2 and Advanced-RNP1 are expected to be included in a future revision of the PBN Manual; 1a means that the navigation application is limited to use on STARs and SIDs only; 1b means that the area of application can only be used after the initial climb of a missed approach phase 1c means that beyond 30NM from the airport referenc
