Abstract

Systems and apparatus are provided for head-mountable cockpit displays for providing information related to an aircraft system to a user. A cockpit display system comprises an eyeglass frame adapted for wearing on the head of the user. The eyeglass frame has a perimeter defining a field of view. A display element is mechanically coupled to the eyeglass frame and aligned with a bottom portion of the field of view. Display electronics are coupled to the display element, and an avionics system is coupled to the display electronics. The display electronics are configured to render an image of a cockpit instrument panel associated with the avionics system on the display element.

First claim

What is claimed is:

1. A display system comprising: a support structure, the support structure being adapted to be worn on a head of a user during operation of an aircraft, the support structure having a perimeter defining a field of view aligned with the eyes of the user, wherein the field of view is substantially transparent: a display element coupled to the support structure, wherein the display element occupies a bottom portion of the field of view and does not occupy an upper portion of the field of view; a processor coupled to the display element; an electronic system coupled to the processor, wherein the processor is configured to display a graphical representation of an instrument panel associated with the electronic system on the display element at a downward angle relative to a forward line of sight of the user, the instrument panel providing graphical information indicative of one or more characteristics of the electronic system during the operation of the aircraft; and a sensor coupled to the processor and configured to obtain a signal indicative of the graphical representation, wherein the processor is configured to analyze the signal to determine if the display system is operating properly.

2. A head-mountable device suitable for wearing during operation of an aircraft, the head-mountable device comprising: an eyeglass frame adapted to be worn on the head of a user, the eyeglass frame defining a field of view aligned with the eyes of the user, wherein the field of view is substantially transparent; a display element supported by the eyeglass frame, wherein the display element obstructs a lower portion of the field of view and an upper portion of the field of view is not obstructed by the display element; a display controller coupled to the display element, the display controller being configured to: control rendering of an image on the display element, wherein the image contains graphical information associated with operation of the aircraft; and present the image rendered on the display element as a wide-angle image at a downward angle relative to a forward line of sight of the user; and a sensor coupled to the processor and supported by the eyeglass frame, the sensor being configured to obtain a signal indicative of the image, wherein the processor is configured to verify the image accurately reflects information associated with a subsystem of the aircraft.
