Abstract: An estimation device for estimating, during an aircraft approach procedure for landing on a runway following a predefined runway approach, a deviation relative to a reference guidance axis corresponding to the predefined runway approach, and a speed of an aircraft relative to the runway, the approach procedure being carried out with a landing aid device including at least one transmitter station configured to transmit the reference guidance signal defining the reference guidance axis. The estimation device includes an acquisition unit for a current aircraft position of a geo-positioning system, an acquisition unit for a current acceleration of an inertial unit, an acquisition unit for a current lateral and vertical deviation of a landing aid device, a filtering unit for estimating an unbiased aircraft speed, a filtering unit for estimating a current lateral deviation, a current vertical deviation as well as current lateral and vertical speeds of the aircraft.

Abstract: A method and system allowing fully autonomous automatic take-off using only images captured by cameras on the aircraft and avionics data. The system includes an image capture device on the aircraft to take a stream of images of the runway, image processing modules to estimate, on the basis of the streams of images, a preliminary current position of the aircraft on the runway and to assign a preliminary confidence index to the estimate. A data consolidation module can determine a relevant current position of the aircraft on the runway by consolidating data originating from the image processing modules with inertial data to correct the estimate of the preliminary current position and determine a relevant confidence index using a current speed of the wheels of the aircraft to refine the preliminary confidence index. A flight control computer can control and guide aircraft take-off.
