    摘要: The purpose of the present invention is to accurately land a vertical take-off and landing aircraft on a target landing point. This automatic landing system is provided with: an imaging device mounted on a vertical take-off and landing aircraft; a relative-position acquisition unit that performs image processing on an image, of a marker provided to a target landing point, captured by the imaging device, and that acquires a relative position between the vertical take-off and landing aircraft and the target landing point; a relative-altitude acquisition unit for acquiring a relative altitude between the vertical take-off and landing aircraft and the target landing point; and a control unit for controlling the vertical take-off and landing aircraft in a plurality of control modes so that the relative position becomes zero, wherein the control modes include a hovering mode and a landing mode. In the hovering mode, the relative altitude of the vertical take-off and landing aircraft is lowered to a predetermined relative altitude when the relative position is within a first threshold value. The transition to the landing mode takes place upon satisfaction of predetermined conditions including a condition in which the relative position is within a predetermined threshold value which is less than the first threshold value. In the landing mode, the relative altitude of the vertical take-off and landing aircraft is further lowered so as to make a landing on the target landing point.

    摘要: A system for calculating weight and distribution on an aircraft. The system comprises an aircraft, at least one cabin camera (100a-100n) configured to view the cabin of the aircraft, an image collector (110) configured to collect images from the at least one cabin camera (100a-100n) and a processor. The processor is configured to perform the following steps: a) detecting passengers and/or hand baggage from the images collected from the image collector, b) estimating positions of the passengers and/or hand baggage from the images collected from the image collector, and c) estimating weight of the passengers and/or hand baggage from the images collected from the image collector. The processor also calculates a real-time weight distribution of the aircraft based on the estimates provided in steps a) - c).

    摘要: La présente invention concerne un procédé de pilotage d'un aéronef (1) ayant une suite (30) de senseurs comprenant une pluralité de senseurs de navigation (31) dissimilaires. Ce procédé comprend les étapes suivantes: (i) détermination (STP1) d'au moins un paramètre de condition de vol variant en fonction de conditions météorologiques ou de la position de l'aéronef (1), (ii)-sélection (STP2) d'un jeu de senseurs (50) en fonction de chaque paramètre de condition de vol selon un modèle de sélection embarqué dans ledit aéronef (1), ledit jeu de senseurs (50) comprenant au moins un senseur de navigation de ladite suite (30) et générant au moins une information de pilotage, (iii) génération (STP3) avec un contrôleur de commande (20) d'au moins un signal de commande pour piloter l'aéronef (1) basé au moins sur chaque information de pilotage.

    摘要: A method of determining whether a landing event of an aircraft is hard may comprise: receiving, by a controller (230) via a stroke position sensor (116), a stroke profile as a function of time for a shock strut; receiving, by the controller via a gas pressure sensor (110), a gas pressure in a gas chamber of the shock strut; receiving, by the controller via a wheel speed sensor (120), a wheel speed of a tire in a landing gear assembly; calculating, by the controller, multiple time dependent functions based on the stroke profile of the shock strut, based on the gas pressure, a shock strut temperature, and the wheel speed; and comparing, by the controller, the multiple time dependent functions to respective predetermined thresholds to determine whether the landing event is hard.
