A present novel and non-trivial system, device, and method for presenting course deviation information on an aircraft display unit are disclosed. Lateral/vertical boundaries are established based upon lateral/vertical navigation data provided by one or more navigation data sources. Lateral/vertical deviation symbology data set(s) representative of lateral/vertical deviation scale(s) are generated and adapted to the lateral/vertical navigation data. The adapted lateral/vertical deviation symbology data set(s) representative of adapted lateral/vertical deviation scale(s) are provided to a display unit, whereby symbology(ies) of such adapted scale(s) are presented on a screen of the display unit. Each adapted scale is comprised of a desired course indicator and at least one deviation indicator, where the desired course indicator corresponds to a desired course and each deviation indicator corresponds to one navigation boundary. In response to changes of aircraft deviation, all indicators move together in unison within their respective, adapted deviation scale. |
