Abstract: A display system in an aircraft cockpit, including a plurality of display surfaces, a processing module configured to host applications capable of generating images to be displayed on one or more display surfaces, a graphic generation module configured to generate a composite graphic flow including images from one or more applications and intended to be displayed on different display surfaces, wherein each display surface is configured to receive the composite graphic flow and to extract images for display on that display surface.

Abstract: The invention relates to an electronic system comprising an electronic computer, in the presence of an external request to execute a source application whose executable has been previously loaded within a first dedicated area of the memory, being at least configured to: instantiate a clone application of the source application by: duplicating the executable of the source application to create the executable of the clone application, and by storing it in a second area of the memory distinct from the one dedicated to the source application, and by generating a request, internal to the computer, to execute said at least one clone application, execute the source and clone(s) applications independently, generate a single output based on comparing the result of the execution of the source and clone(s) applications.
