Abstract

Disclosed is an aircraft computing and display device that includes a general purpose processor, a touch screen display and a housing. The processor executes logical instructions in the form of computer software. The touch screen display forms an interactive human-machine interface by displaying video graphics and accepting user input with a pressure sensitive surface. The housing retains the processor and the touch screen and is physically configured to replace a legacy device mounted in a cockpit instrument panel of the aircraft.

Claims

1. An aircraft computing and display device, comprising:

a general purpose processor for executing logical instructions in the form of computer software and a memory for storing the software;

a touch screen display that forms an interactive human-machine interface by displaying video graphics and accepting user input with a pressure sensitive surface; and

a housing that retains the processor, the memory and the touch screen, the housing physically configured to replace a legacy device mounted in a cockpit instrument panel of the aircraft, the legacy device being a user control interface for a subsystem of the aircraft and the legacy device including a display and mechanical buttons, each button associated with a fixed function,

wherein the aircraft computing and display device is a form-fit-function replacement for the legacy device such that the aircraft computing and display device connects to aircraft wiring dedicated to the legacy device; and

wherein, in a legacy mode, the aircraft computing and display device executes logic to carry out functions performed by the legacy device, to replicate layout and content of the legacy device display on the touch screen display and to display a virtual keyboard on the touch screen display to replicate input functionality and mechanical button arrangement of the mechanical buttons.

4. The aircraft computing and display device according to claim 1, wherein the legacy device is a control display navigation unit (CDNU) that interfaces with an avionics subsystem as a control head for the avionics subsystem and wherein the avionics subsystem is located in the aircraft and apart from the cockpit instrument panel.

5. The aircraft computing and display device according to claim 1, further comprising a network interface to a military command and control facility.

6. The aircraft computing and display device according to claim 5, wherein, in a moving map mode, the aircraft computing and display device executes logic to display a map that is updated relative to movement of the aircraft and to display an overlay with tactical information received from the command and control facility, the overlay displayed in conjunction with the map and the overlay is updated with the map relative to movement of the aircraft.

8. The aircraft computing and display device according to claim 6, wherein the overlay is generated without cockpit crew interaction with the aircraft computing and display device.

9. The aircraft computing and display device according to claim 1, wherein the aircraft computing and display device executes logic to place the aircraft computing and display device in a navigation mode and the navigation mode logic includes logic to add a flight plan waypoint upon activation of the touch screen.

10. The aircraft computing and display device according to claim 9, wherein the added waypoint has coordinates corresponding to the activated location of the touch screen relative to a display map.

13. The aircraft computing and display device according to claim 1, wherein the aircraft computing and display device is further operable in at least one of a navigation mode, a checklist mode or an emergency procedures mode.

14. The aircraft computing and display device according to claim 1, further comprising a video capture interface.

15. In combination, an aircraft having a cockpit instrument panel with an opening corresponding to a removed legacy cockpit instrument panel device and an aircraft computing and display device according to claim 1, wherein the aircraft computing and display device is secured in the opening as a form-fit-function replacement to the legacy cockpit instrument panel device.
