RNP-scaled waypoint symbology generating system, device, and method

摘要

A system, device, and method for generating an RNP-scaled waypoint symbology presentable to a pilot are disclosed. The symbology generating system may include a source of source of navigation data, a symbology generator (SG), and a presentation system. The SG may be configured to acquire navigation data representative of one or more distance measurements of an area navigation system or a required navigation performance system; and generate presentation data as a function of each distance measurement. The presentation data could be representative of waypoint symbology presentable to a viewer. In some embodiments, the waypoint symbology may be comprised of a two-dimensional object or a three-dimensional object having a plurality of shapes centered on a reference line, where a size of a first shape may be scaled to a first distance measurement, and a size of a second shape may be scaled to a second distance measurement.

主权项

1. A system for generating waypoint symbology, comprising:
a source of navigation data representative of
a first measurement comprised of a required navigation performance or a total system error, anda second measurement comprised of at least one of an allowable flight technical error and an estimated position uncertainty; and a symbology generator including at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code and configured to:
acquire the navigation data;generate presentation data representative of waypoint symbology as a function of the first measurement and the second measurement, where
the waypoint symbology is comprised of an object defined by a plurality of concentric shapes centered on a reference line, where
a size of a first concentric shape is scaled to the first measurement, anda size of a second concentric shape is scaled to the second measurement; andprovide the presentation data to a presentation system, whereby
the waypoint symbology is presented to a viewer of at least one aircraft display unit.
