1. An aircraft comprising:
a cockpit display device in an aircraft cockpit; and
a flight deck system comprising a controller, wherein the controller is configured to:
retrieve IFR and/or VFR (IFR/VFR) data comprising a plurality of topography information, air traffic services information, information regarding airports that have an instrument approach procedure or a minimum 3000 foot hard surface runway, airways/route data, cruising altitudes, fixes/ATC reporting points, limits of controlled airspace, military training routes, off route obstruction clearance altitudes (OROCA), radio aids to navigation, RNAV routes, military training routes (MTRs), special use airspace (SUA), military operations area (MOA), and airport data from a pre-stored raster chart;
assign a different priority level from a plurality of priority levels to each of a plurality of types of the IFR/VFR data, wherein the topography information is assigned to a first priority level;
retrieve geo-referenced data from one or more geo-referenced data sources comprising one or more of an EGPWS (enhanced ground proximity warning system) terrain database data, an airports database data, a navigation aids (NAVAID) database data, an airspace database data, flight plan data, weather data, and traffic data from one or more geo-referenced data sources;
assign a different priority level from a plurality of priority levels to each of a plurality of types of the geo-referenced data, wherein the flight plan data is assigned to a second priority level and the weather data and traffic data are assigned to a third priority level;
generate a graphical display comprising a plurality of display levels including a first display level and a second display level, wherein IFR/VFR data assigned to the first priority level and any geo-referenced data assigned to the first priority level are included in the first display level, and IFR/VFR data assigned to the second priority level and any geo-referenced data assigned to the second priority level are included in the second display level;
cause the first display level of the graphical display to be displayed on the cockpit display device during a mission while the second display level of the graphical display is hidden from display; and
cause the second display level to be displayed as an overlay over the first display level during the mission when selected.
