Abstract: A wearable electronic display system detects aircraft flight related conditions, compares the detected flight related conditions with rules or procedures, retrieves flight condition information relating to phase of flight, and displays small amounts of contextually relevant flight condition information on a display screen.

Abstract: Electronic map display information is generated. A map display comprising mapping data for a geographic region is generated. The mapping data is rendered on a map display. A plurality of concentric rings are overlaid on the map display. Each of the rings are indicative of a scaling factor for the mapping data. The scaling factor is adjusted based in a context of the map display.

Abstract: In one advantageous embodiment, a method for managing presentation of a navigational chart on a touchscreen display device is presented. A user input is received on a surface of the touchscreen display device on which the navigational chart is presented. A number of portions of the navigational chart corresponding to the surface on which the user input was received are identified, using a processor unit connected to the touchscreen display device. A number of graphical indications are presented on the navigational chart in association with each of the number of portions identified by the processor unit.
