Patent ID: 8532849

Claim:
A system for presenting course deviation information on an aircraft display unit, such system comprising: at least one source of navigation data; a symbology generator configured to receive first navigation data, establish a plurality of first desired course navigation boundaries based upon the first navigation data, generate a first deviation symbology data set representative of a first course deviation scale, where such first course deviation scale is comprised of a desired first course indicator and at least one first deviation indicator, where the desired first course indicator corresponds to a desired first course and each first deviation indicator corresponds to one first desired course navigation boundary, derive first deviation data from the first navigation data, where such first deviation data is representative of first course deviation, adapt the first deviation symbology data set to the first deviation data, such that the placement of the desired first course indicator and each first deviation indicator is based upon the first course deviation, and provide the adapted first deviation symbology data set representative of an adapted first course deviation scale to a display unit; and the display unit configured to receive the adapted first deviation symbology data set, and present an image represented in the adapted first deviation symbology data set on a screen of the display unit, whereby symbology of the adapted first course deviation scale is presented, and the desired first course indicator and each first deviation indicator move together in unison in response to changes in the first course deviation.
