Abstract
In the field of secure avionics systems for aircraft, a system comprises strictly three display units and three or four graphics generation computers connected to the display units. Each display unit comprises a single large-size screen able to display two totally independent half-images, and all the power supply, control and display circuits are doubled-up such that a single failure brings about the loss, at the most, of one half-screen. Each display unit is connected to two graphics generation computers at least, such that the failure of one computer does not affect the display.
