Abstract: A system for automatic landing of an aircraft on a runway, including an onboard image capture system, image analyzer for detecting in an image a landing runway and determining characteristics of a segment connecting a planned point of impact on the runway and a vanishing point of the image, a measurement module for measuring observables in an inertial frame tied to the runway, on the basis of characteristics of the segment, the observables including a first observable, a second observable, and a third observable, an estimator for estimating longitudinal, lateral and vertical position deviations of aircraft position relative to point of impact from measurements of the first, second and third observables, and guidance for determining aircraft guidance orders from the longitudinal, lateral and vertical deviations and of the relative heading angle.

Abstract: A system and method are disclosed for automatic landing of an aircraft on a landing runway, including an on-board video camera intended to take images of the ground, image processor to extract from these images visual features of the landing runway, guidance system determining guidance commands of the aircraft to bring it into a nominal approach plane and to align it with the axis of the landing runway, from the respective positions of the visual features of the landing runway, in at least one of the images, where the guidance commands are supplied to a flight control computer.
