  • Patent number: 9773423
    Abstract: A method of generating and displaying a consolidated warning making use of collision avoidance warnings as generated by various collision avoidance systems (TCAS, HTAWS, OWS, FMS, N) fitted to an aircraft. The consolidated warning is generated in application of a selection criterion for selecting collision avoidance warnings that relate to the aircraft performing an obstacle avoidance maneuver vertically upwards. The consolidated warning is displayed in the form of a plurality of display elements comprising display elements arranged as superposed strips. A first strip indicates the presence of an obstacle to be avoided by a vertical avoidance maneuver, and a second strip that is segmented to indicate the bearing position of said obstacle relative to the aircraft.

  • Patent number: 9441972
    Abstract: A method of assisting in the navigation of a rotorcraft by displaying in flight a dynamic representation of the outside world (Me) in the event of a loss of visibility (brown-out/white-out). Front maps with incorporated localization are generated on the basis of front images captured by a set of front cameras. Terrain elevation data is generated from images captured by complementary sets of lateral and rear cameras. In the event of a loss of visibility, a reconstituted world (Mr) is prepared from the front maps with incorporated localization. On request of the pilot, an extrapolated world (Mex) is prepared by adding terrain elevation data to the front maps with incorporated localization, in compliance with the common time and the relative positions of the various sets of cameras between one another.

  • Patent number: 9401093
    Abstract: A procedure for the detection and display of the ground and of obstacles through the use of detection means installed onboard a vehicle, which detection means send measurement signals toward the ground and receive a plurality of elementary plots (Pe). The procedure makes it possible to create a grid of the ground along a horizontal plane, with each ground cell (Ms(i,j)) consisting of an elementary plot (Pe) having a minimum altitude Zmin(i,j)), and with each other elementary plot (Pe) corresponding to the ground cell (Ms(i,j)) and having a different altitude (Zn(i,j)), thereby forming an obstacle plot (Pon(i,j)). Each newly received elementary plot (Pe) is then compared against the corresponding ground cell (Ms(i,j)) and processed according to its altitude (Zn(i,j)). The ground cells (Ms(i,j)) and/or the obstacle plots (Pon(i,j)) are displayed on display means in order to indicate to the pilot of the vehicle the potential obstacles other than the ground.

  • Patent number: 9004400
    Abstract: A buoyancy system (2) includes at least one float (3), a deployment assembly (30) having at least one deployment member (34) for deploying the float (3), an engagement controller (5) which activates the deployment assembly (30), and at least two immersion sensors (20) for issuing an order for automatic deployment of the float (3) to the deployment assembly (30). The deployment assembly (30) is provided with a memory (31) containing a pre-established list of events. The deployment assembly (30) deploys each float (3) when a predetermined event occurs.

  • Patent number: 8577608
    Abstract: A method essentially comprising a step of storing each plot mesh. Each plot mesh receiving plots sent thereto by detector means and retaining in memory at least the altitude of the highest plot and the number of plots neighboring said highest plot in said mesh. The altitude and the number of plots neighboring are updated each time a new plot is sent to the plot mesh. A step of rejecting plot meshes is presenting a number of neighboring plots that is less than a predetermined rejection threshold value. The rejection threshold value is a function of the position of the mesh relative to the detector means. A step is preparing the local terrain elevation database from the plot meshes (M(i,j)) that are not rejected.

  • Patent number: 8566018
    Abstract: The present invention relates to a piloting assistance method for an aircraft, the method consisting in using data from at least one active telemeter sensor (A) in order to construct a sensor safety cordon (B) for avoiding the terrain and obstacles that are overflown. The method; defines and calculates angular sectors (w) over the field of regard facing the pilot; constructs a terrain safety cordon (D) using at least one terrain database (C); for at least some of the angular sectors (w), constructs a hybrid safety cordon (E) that, in each of the angular sectors (w) in question, makes use of the higher of the sensor and terrain safety cordons (B, D); and displays one of the cordons selected from: the hybrid safety cordon (E), the terrain safety cordon (D), and the sensor safety cordon (B).

  • Patent number: 8392475
    Abstract: The present invention relates to a method of flying safely and at low altitude in an aircraft, in which method unsafe relief (R0) of terrain is determined as is the position of at least one high point (4, 5) representing an obstacle (4?, 5?) overlying said unsafe relief (R0). A main volume (V0) is added to said unsafe relief (R0), the main volume being defined between a main volume base (2) placed on the unsafe relief (R0) and an envelope (1), thereby obtaining safe relief (R1) for overflying that contains at least said unsafe relief (R0) and said main volume (V0), said main volume base (2) having an area (2?) defined by a closed peripheral curve (3) resting on said unsafe relief (R0), said envelope (1) being generated using a moving segment (S) of predetermined length (L) extending from said high point (4, 5) to a second point (3?) moving along said peripheral curve (3).

  • Patent number: 8364330
    Abstract: A method of assisting the piloting of an aircraft (60) at low altitude over terrain (S), in which method, during a first stage, a framework (10) is constructed from at least one main segment (40) and during a second stage a setpoint flight path (50) is constructed. More precisely, during the first stage, said main segment (40) is subdivided automatically into a plurality of secondary segments (41, 42, 43), each of said secondary segments (41) being situated at the same setpoint height above the highest point of the underlying terrain, with two adjacent secondary segments (41) being in alignment or connected together by a bar (44) that extends vertically in a vertical section.
