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.

The device of claim 9, wherein the size of the second concentric shape increases with a decrease of the estimated position uncertainty, andthe size of the second concentric shape decreases with an increase of the estimated position uncertainty. 14. The device of claim 9, wherein a visual appearance of the waypoint symbology is alterable in response to at least one level of threat. 15. A method for generating waypoint symbology, comprising: acquiring, by at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code, 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;generating 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; andproviding the presentation data to a presentation system, whereby the waypoint symbology is presented to a viewer of at least one aircraft display unit. 16. The method of claim 15, wherein the object is a two-dimensional object. 17. The method of claim 15, wherein the size of the second concentric shape increases with an increase of the allowable flight technical error, andthe size of the second concentric shape decreases with a decrease of the allowable flight technical error. 18. The method of claim 15, wherein the object is a three-dimensional object. 19. The method of claim 15, wherein the size of the second concentric shape increases with a decrease of the estimated position uncertainty, andthe size of the second concentric shape decreases with an increase of the estimated position uncertainty. 20. The method of claim 15, wherein a visual appearance of the waypoint symbology is alterable in response to at least one level of threat.
