Abstract:
A method and device including a unit to extract a linear terrain profile stored in memory, a terrain height for a current distance of the aircraft, a unit for determining a current height of the aircraft with respect to the terrain, using at least one measurement taken by a radar altimeter, a unit for computing a first current altitude of the aircraft, using the terrain height and the current height, a unit for computing a second current altitude of the aircraft, corresponding to an altitude on an approach profile of the current position of the aircraft and a unit for computing the difference between the first and second current altitudes, the difference being transmitted to a guidance unit to vertically guide the aircraft.
Abstract:
A tool-support system for working on holes of a surface. The tool-support system includes two rails fixed to the surface and having imprints regularly distributed over their length, and a mobile tool-support including a mobile optical system capturing an image of the surface. For each rail, at least one wheel is adapted to be moved on the rail, and includes on its rolling strip counter-imprints complementary to the imprints. A mobile tool carries a working tip, and a control unit is configured to control the movement of the mobile tool-support, of the tool and of the optical system to analyze an image captured by the optical system and to detect the presence of a hole. A tool-support system of this kind can therefore move along the rails without slipping while detecting the holes to work on them.
Abstract:
A system for controlling an aircraft control parameter including a control interface including a mobile element configured to move on a travel, of which at least two portions are separated by a neutral position; a return element bringing the mobile element back to the neutral position when it is not actuated; and an interaction element, and a control unit configured to memorize an item of information corresponding to a first position of the mobile element at an instant of activation of the interaction element; and generate a setpoint of the aircraft control parameter, as a function of a control associated with the first position of the mobile element for which said information has been memorized; or a current position of the mobile element, when this current position is situated on the same portion of travel as the first position and is more remote than the latter from the neutral position.
Abstract:
A system, device and method for recording data in an aircraft including a memory and a network interface through which it is connected to the network. This device is configured for acquiring information from the avionics communication network, and information relative to characteristic events relative to operation of the aircraft, generating indexes corresponding to different times, recording, in a first part of the memory, indexed data corresponding to the information coming from avionics communication network, the indexed data including a set of recordings, each recording corresponding to the combination of information coming from the avionics communication network and an index corresponding to a time associated with that recording; and recording, in a second part of the memory, for several of the characteristic events, information of correspondence between the characteristic event in question and an index corresponding to a time associated with that characteristic event.
Abstract:
A high-lift trailing edge flap system for an aircraft wing unit is provided. In high-lift trailing edge flap system, the backward movement and the inclination of the trailing edge flap in the extended position are dissociated in order to allow for the incorporation of the actuating mechanism into the wing in the stowed position.
Abstract:
A system for monitoring scheduled turnaround activities and alerting on time deviation from the scheduled turnaround activities is disclosed. The system includes a ground computing station system, an aircraft on-board system, a cloud, and user interface. The cloud is communicatively coupled to the ground station computing system and the aircraft on-board system. The cloud includes processor and memory. The memory includes an analytics module to obtain actual start and end time stamps associated with scheduled turnaround activities, from touchdown to takeoff of an aircraft, from aircraft on-board systems and a ground station system. The analytics module to determine time deviation of scheduled turnaround activities by analyzing the obtained actual start and end time stamps. The user interface to present each scheduled turnaround activity and determined time deviation of the scheduled turnaround activities.
Abstract:
A display system and method including screens in a cockpit of an aircraft. A control unit is configured to command the display according to a normal display mode, wherein the control unit is configured so as to command the display such that subsequent to the occurrence of an event on board the aircraft leading to the display of an interactive element in an interaction window, the control unit commands the display of the interaction window on one of the screens of the screens at least while an action by an operator is required on the interactive element, and a reconfigured display mode, wherein the control unit is configured to command the display, on a second screen including a signaling area, of a display window that is normally displayed on a first screen in the normal display mode, and to command the display of an indicator in the signaling area if the interaction window is not displayed on a screen of the screens when an action by an operator is required on the interactive element.
Abstract:
A process for checking when tightening a threaded fastener that it has been tightened on the complete threads of the fastener. In order to do this the process comprises detecting different gradients in a tightening graph representing torque as a function of another parameter and comparing each gradient with predetermined values. According to the portions of graph detected and their gradient values it is possible to determine whether tightening is correct and has taken place on the complete threads of the fastener, or if not it is possible to identify a cause of failure.
Abstract:
A method and device are disclosed for automatically managing a flight path change on an aircraft, in particular for a low-level flight. The method determines a first deviation between the current position and a current path of the aircraft and a second deviation between this current position and a new path of the aircraft and changes the flight path by replacing the current path by the new path, if at least the absolute value of the difference between this first deviation and this second deviation is less than or equal to a maximal allowed distance during at least a predefined time period.
