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: A method for determining and transmitting slant visibility range information for a runway at a predetermined decision altitude, including a step of acquiring, by a first aircraft, an image of a surrounding scene located outside and ahead of the aircraft, a step of analyzing the image to detect visual runway references in the image and measure distance between the aircraft and each detected runway reference, a step of transmitting slant visibility range information to the ground station, implemented by the first aircraft, the information including a distance between a visual runway reference and the aircraft measured in the analysis step if at least one runway reference has been detected, or if not information according to which no visual runway reference was able to be detected, and a step of transmitting, by the ground station, slant visibility range information associated with the runway to at least one second aircraft in flight.

Abstract: A method of synthetic visualization of a scene viewed from an aircraft and synthetic vision system. The system includes a processing unit for generating a synthetic image of a scene ahead of the aircraft, a unit for displaying on a visualization screen a background image corresponding to this synthetic image and symbols for piloting the aircraft, and a monitoring device including a unit for generating at least two virtual control elements, representations of the control elements integrated into the synthetic image, a unit for detecting on the synthetic image the representations and their position, and a unit for verifying whether these positions are consistent with position of a line of zero pitch and/or of a line of zero roll of the aircraft, the display being carried out only in case of consistency between these positions, that is to say the absence of any problem of orientation of the synthetic image.

Abstract: The device for assisting the landing of an aircraft in a phase of descent for the purpose of a landing on a runway with the help of an instrument landing assistance module includes an image capturing module for capturing a sequence of successive images of the ground, an image processing module, a monitoring module for detecting on the processed images at least one visual characteristic corresponding to a runway, a computation module for computing a current position of the aircraft and a comparison module for comparing the computed current position with a signal representative of a current position of the instrument landing assistance module, a go-around warning being transmitted to a display unit, if the current positions are not substantially identical.

Abstract: This method of determining the risks of collision of an aircraft (1) when travelling on the ground comprises the steps of: determining the path of at least one of several parts to protect of the aircraft (1), determining a protection volume (VR, VP) associated with said at least one of several parts to protect of the aircraft, in which the shape in a horizontal plane of said protection volume depends on said path of said at least one of several parts to protect, detecting an object entering said protection volume, and generating a warning in response to detecting said object.
