Abstract: The enhanced flight vision system of an aircraft comprises an image acquisition system provided to acquire images of an outside environment of the aircraft, and a display system configured to allow information to be displayed on a display unit overlayed with the outside environment of the aircraft. The display system is configured to receive images produced by the image acquisition system and to display these images on the display unit. The image acquisition system is configured to associate ancillary information with at least a part of the images produced and the display system is configured to check the integrity of an image received from the image acquisition system, based on the ancillary information associated with that image; and in the absence of integrity, deactivate the display on the display unit of at least the image received from the image acquisition system.

Abstract: An aircraft cockpit display system comprises a display device configured to be secured to a user's head, a sensor for sensing the position, orientation and/or acceleration of the user's head and a display computer controlling the display on the display device of at least one first consistently displayed symbol and of at least one second non-consistently displayed symbol. The display computer determines an angular velocity value of the user's head based on information provided by the sensor and controls the display on the display device in a first display mode when the angular velocity value is less than or equal to a predetermined angular velocity threshold and in a second display mode if not. In the second display mode, the visibility of the second piloting assistance symbol to the pilot is less than the visibility of the second piloting assistance symbol in the first display mode.

Abstract: A flight control indicator for an aircraft, intended to supply the engine pressure ratio, includes acquisition and processing units (2, 3) which determine the actual value of the engine pressure ratio and a display unit (4) provided with a dial (6) and with a needle (7) whose position on the dial (6) corresponds to the actual value of the engine pressure ratio. Moreover, the acquisition and processing units (2, 3) determine minimum and maximum values for the engine pressure ratio, and the display unit (4) presents on the dial (6) a circular sector (8) which is delimited by two radii (8A, 8B) whose positions correspond respectively to the minimum and maximum values for the engine pressure ratio.
