Abstract: An automated taxi system for an aircraft includes a mapping module configured to generate a collaborative map that identifies traffic within the airport environment, a path trajectory module configured to receive digital taxi clearance from an Air Traffic Control (ATC) identifying a destination within the airport environment, such as a designated take-off runway, and to generate a taxi path trajectory to the destination, a guidance module configured to compute guidance instructions based on the taxi path trajectory, and an aircraft protection module configured to identify obstacles or incursion risks on the collaborative map in the taxi path trajectory and to modify the guidance instructions to avoid the obstacles or incursion risks.

Abstract: An automated aircraft taxi system for an aircraft taxiing within an airport environment implements a collision-avoidance function. The collision-avoidance function triggers revision of guidance instructions and or alerts the pilots of the aircraft when a predicted trajectory of moving objects intersects a taxi path trajectory of the aircraft. The collision-avoidance function disregards an identified object that is moving on a taxiway in the airport environment when a predicted trajectory of the identified object does not intersect the taxi path trajectory of the aircraft according to the location of the identified object and the layout of taxiways on the airport map.

Abstract: A device comprising a radar for taking at least one radar image of the terrain in front of the aircraft in a zone containing at least one characteristic pattern, the position of the characteristic pattern being known, an image processing unit for detecting, on the radar image taken by the radar, a characteristic symbol representing the characteristic pattern, a computation unit for determining, from at least the position of the characteristic symbol in the image and from characteristics of the radar image acquisition, relative position information illustrating the position of the aircraft in relation to the characteristic pattern, and for determining the position of the aircraft, from the relative position information and from the known position of the characteristic pattern, and a unit for transmitting at least the position of the aircraft to at least one user system, for example a landing aiding system or an SVS display.

Abstract: The disclosure herein relates to a measurement system to measure characteristics of the velocity vector of an aircraft in relation to a surrounding air mass, the measurement system comprising—a frontal surface of the aircraft, two primary sensors, each being fixed to the frontal surface of the aircraft and able to deliver an output value relating to the deformation experienced by the sensor, and a processing unit able to receive the output values and able to calculate the angle of attack and/or the velocity of the aircraft on the basis of these output values.
