The invention relates to a system for automatically inspecting a surface of an object such as an aircraft (), a transport vehicle, a building or an engineering structure, said surface being liable to contain a defect. The system is characterized in that it comprises a fleet comprising at least one flying robot (), each flying robot comprising a module for acquiring images of at least one portion of the surface to be inspected, and a module for processing the acquired images, which module is suitable for providing information representative of the state of each inspected surface portion, which information is called the processing result.

A method for the three-dimensional representation of the trajectory of an aircraft in flight implemented in a navigation system of an aircraft is provided. The flight plan of the aircraft comprises imposed georeferenced trajectories and predicted non-georeferenced trajectories. When the trajectory of the aircraft is dependent on a non-georeferenced flight setpoint, the three-dimensional representation method is an iterative process comprising the following steps: computing a predicted trajectory arising from at least one computed trajectory extending over a determined distance or duration; computing a smoothed trajectory from the predicted trajectory in order to obtain a resulting trajectory; computing a displayed trajectory, the trajectory being equal to the resulting trajectory corrected for constant deviations or deviations depending on the application of setpoints from the flight director; and displaying the displayed trajectory.

A method and device for displaying vertical constraints of an aircraft, an associated program produce and aircraft are disclosed. In one aspect, the vertical constrains are displayed on a display device of the aircraft, the display device being part of an aircraft piloting system, the method being implemented by an electronic device that is part of the aircraft piloting system. The method includes acquiring at least one vertical constraint of the aircraft, computing a representative slope value associated with the vertical constraint, and displaying a symbol depicting the vertical constraint at the representative slope value associated with the vertical constraint on a slope scale.

A method for the three-dimensional synthetic representation of the trajectory of an aircraft in flight being implemented in a flight and navigation system of an aircraft comprising a display system allowing synthetic images to be displayed, the flight plan of the aircraft comprises a predicted trajectory dependent on a non-georeferenced flight setpoint, the display of the predicted trajectory taking the form of a path represented by two limits separated by a determined width. The path comprises two branches, each branch positioned on the side of one of the two limits, each branch represented by a straight segment whose origin is a point located on the path at the current time and whose terminus is a point located at a determined distance away from the point of origin, the slope of the straight segment representative of the tangent to the predicted trajectory at the current time.

A method and device for controlling at least one actuator control system of an aircraft, an associated computer program product and aircraft are disclosed. In one aspect, the method includes determining a variation in thrust of the aircraft for controlling a variable relating to the aircraft relative to a set point, calculating a first control command signal to be sent to an engine control system in order to obtain the variation in thrust, and transmitting the first control command signal to the engine control system. The controlled variable can be an acceleration along a direction taken by a speed vector among the air speed vector and the ground speed vector and the set point can be an acceleration set point along the direction.

A method for predicting a short-term flight path of an aircraft, a computer program product, an associated prediction device, a guidance method, and a guidance system of an aircraft are disclosed. In one aspect, the flight path of the aircraft is associated at each time moment with a vector including at least one component from among a position of the aircraft, attitudes of the aircraft and order 1 and 2 time derivatives of the position and attitudes.

The method includes acquiring a control signal representative of a displacement of a primary control member of the aircraft and predicting, at a subsequent prediction time, at least one component of the short-term flight path of the aircraft.

This method for determining an obstacle avoidance guidance law for an aircraft is implemented by a system for determining said guidance law. The aircraft comprises a collision avoidance system adapted to detect a collision risk with the obstacle and said determination system. This method comprises determining one or more set points from among flight path angle and speed set points, at least one set point depending on at least one vertical speed limit value, at least one set point comprising a vertical component in a vertical direction, each limit value being provided by the collision avoidance system following the detection of a collision risk with the obstacle; and computing the avoidance guidance law as a function of the determined set points. During the determination step, at least one determined set point comprises a longitudinal component in a longitudinal direction perpendicular to the vertical direction.
