Device and method for desensitizing a display system to faults

A device for desensitizing an aircraft display system, configured to display a synthetic representation of terrain, to faults, the device comprising:

• one or more processors;
• an acquisition module comprising the one or more processors and configured to acquire environment data and current flight parameters of the aircraft, including at least an attitude, an altitude, a three-dimensional position and a heading;
• a first generation module comprising the one or more processors and configured to generate a first image depicting flight symbology comprising at least one reference zero pitch line, the first image indicating a pitch angle with respect to a zero pitch angle of the aircraft, the reference zero pitch line being representative of the zero pitch angle of the aircraft, the first image being generated on the basis of at least the attitude;
• a second generation module comprising the one or more processors and configured to generate a second image depicting topography of terrain overflown by the aircraft on the basis of at least the attitude, the heading, the three-dimensional position and the environment data;
• a third generation module comprising the one or more processors and configured to generate a third image comprising at least two portions separated by a separating line that is determined on the basis of the attitude of the aircraft, a first portion including pixels having a value that is representative of a first colour range, a second portion including pixels having a value that is representative of a second colour range;
• a fourth generation module comprising the one or more processors and configured to generate a fourth image by superposing the first image, the second image and the third image in that order, the first image being placed in the foreground such that, when the topography of the overflown terrain shown in the second image is shifted downwards because of a fault, the second portion of the third image is visible in the fourth image, thus highlighting said fault;
• and
• a transmission module comprising the one or more processors and configured to transmit, to a user device, a signal that is representative of the fourth image.
