Radar-based system, module, and method for presenting steering symbology on an aircraft display unit

An airborne radar-based module for presenting steering symbology on an aircraft display unit, said module comprising:

• an input communications interface to facilitate a providing of hazard data to a symbology generating processor;
• the symbology generating processor configured to
• receive hazard data from the forward-looking aircraft radar system configured to acquire hazard data, where
• the hazard data is representative of hazard and wind correction information,
• determine a plurality of minimum turn angles based upon boundary tangents of the hazard and wind correction information, where
• such plurality includes a minimum left turn angle and a minimum right turn angle,
• generate first steering symbology data, where
• such first steering symbology data is representative of first steering symbology corresponding to a first minimum turn angle and comprised of a first non-textual, hazard avoidance steering cue presented in a tactical display image, where
• the tactical display image is comprised of at least
• an airspeed indicator,
• an altitude indicator,
• a heading indicator, and
• an attitude indicator comprised of at least pitch and roll indications, and
• provide the first steering symbology data an output communications interface, whereby
• the first non-textual, hazard avoidance steering cue of the first steering symbology data is superimposed against the heading indicator depicted on a tactical display unit;
• and
• the output communications interface to facilitate a providing of the first steering symbology data from the symbology generating processor to a presentation system.
