Abstract

Systems and methods for providing Integrated Modular Avionics (IMA) processing and input/output (I/O) capabilities to existing electronic systems onboard aircraft are disclosed. More specifically, a display processing computer may include a first set of I/O interfaces and a second set of I/O interfaces. The display processing computer may further include at least one first processor in communication with the first set of I/O interfaces and at least one second processor in communication with the second set of I/O interfaces. The at least one first processor may be configured to process data received at the first set of I/O interfaces and provide commands to control a display. The at least one second processor may be configured to provide a set of non-display functions, and further configured to selectively activate a subset of the set of non-display functions based on at least one operating condition of the display processing computer.

First claim

What is claimed is:

1. An avionics display system, comprising:
a display installed onboard an aircraft; and
a display processing computer configured to control the display, the display processing computer configured as a line-replaceable unit (LRU) onboard the aircraft, the display processing computer comprising:
a first set of input/output (I/O) interfaces;
a second set of I/O interfaces operationally separated from the first set of I/O interfaces;
at least one first processor in communication with the first set of I/O interfaces and configured to process data received at the first set of I/O interfaces and provide commands to control the display; and
at least one second processor in communication with the second set of I/O interfaces and configured to provide a set of non-display functions, and further configured to selectively activate a subset of the set of non-display functions based on a connection of the display processing computer with the display, wherein another subset of the set of non-display functions are selectively activated based on a connection of the display processing computer with a second display of the aircraft.

2. The display system of claim 1 , wherein the first set of I/O interfaces and the second set of I/O interfaces are physically segregated within the LRU.

3. The display system of claim 1 , wherein the at least one first processor and the at least one second processor are physically segregated within the LRU.

4. The display system of claim 1 , wherein said at least one first processor is further configured to selectively activate a subset of a set of display functions on the display based on a connection of the display processing computer with the display.

5. The display system of claim 4 , wherein said at least one first processor is further configured to selectively activate another subset of a set of display functions on the second display based on a connection of the display processing computer with the second display.

6. The display system of claim 1 , wherein the subset of the set of non-display functions include flight deck access control, flight warning applications, or power management.

7. The display system of claim 1 , wherein the display processing computer configured as the LRU has established a connection with the display when the LRU is installed.

8. The display system of claim 7 , wherein the display processing computer configured as the LRU has established a connection with the second display when the LRU is removed from a connection with the first display and installed with the second display.
