Methods, systems, and apparatus, including computer programs encoded on computer storage media, for an unmanned aerial system inspection system. One of the methods is performed by a UAV and includes receiving, by the UAV, flight information describing a job to perform an inspection of a rooftop. A particular altitude is ascended to, and an inspection of the rooftop is performed including obtaining sensor information describing the rooftop. Location information identifying a damaged area of the rooftop is received. The damaged area of the rooftop is traveled to. An inspection of the damaged area of the rooftop is performed including obtaining detailed sensor information describing the damaged area. A safe landing location is traveled to.

The general field of the invention is that of the methods for three-dimensional graphic representation of at least one landing runway on a display device of an onboard display system for aircraft, said graphic representation being displayed in a synthetic of an outside landscape, said runway comprising a coloured rectangular form, an outline surrounding said form and markings, the position of the aircraft in relation to said runway being known in a horizontal plane with a first accuracy and in a vertical axis with a second accuracy. When the first accuracy is above a first threshold and/or when the second accuracy is above a second threshold, the appearance of the rectangular form or of the outline or of at least one marking is modified.

The invention relates to a method for guiding an aircraft along a reference path, said method comprising: a) when the altitude of the aircraft is greater than a threshold, estimating (E1) a relative location of the aircraft in relation to a taxiing starting point using a map of the platform and reference points on the ground, b) when the altitude of the aircraft is less than said threshold and before the aircraft is located at the taxiing starting point, estimating (E2) a relative location of the aircraft in relation to the taxiing starting point using data relating to the absolute location of the aircraft and the last relative location estimated at step a), c) when the aircraft is located at the taxiing starting point, guiding (E3) the aircraft on the basis of a location of the aircraft relative to the reference path as estimated using data relating to a set of indicators on the ground.

The runway state determined on the ground by an aircraft and provided to the aircraft on approach does not make it possible to account for possible degradation of the runway occurring since the previous determination of that runway state. Updating of this runway state on the basis of a simple comparison between a desired deceleration and an observed deceleration resulting from a degraded runway is not satisfactory either. The disclosure herein thus provides for obtaining a local stopping distance according to a local runway state characterizing a runway zone on which the aircraft is in movement at the time of the landing, this local stopping distance being estimated based on local measurements made in the aircraft; obtaining a reference stopping distance according to a reference runway state; then comparing these two distances with each other to determine whether the local runway state is more degraded than the reference runway state.

The general field of the invention is that of methods of three-dimensional graphical representation of a landing runway on a viewing screen of an onboard viewing system for aircraft, the said graphical representation being displayed in a synthetic view of an exterior landscape. The graphical representation according to the invention comprises a line disposed along the axis of the runway, the said line being a straight stripe inclined by an angle of between one and a few degrees with respect to the horizontal, the said line beginning at the runway threshold.

Systems, methods and computer-storage media are provided for use of navigational aids. Three-dimensional graphical representations of flight plans, flight paths, waypoints, etc., may be displayed to improve situational awareness. Additionally, dynamic monitoring of airports, waypoints, traffic, etc., may be performed so that real-time updates are available to users. The real-time updates will not only include updated location information and any relevant navigational markers (e.g., updated waypoints, new traffic, etc.) but will also include detailed information related to the navigational markers such as a distance from the marker, an airspeed of the marker (if applicable), and the like.

A stationary object identification system includes memory and a transmitter. The memory has obstacle data stored therein that includes a plurality of parameters associated with each of a plurality of stationary obstacles located at a location, such as an aerodrome. The transmitter is in operable communication with the memory and is configured to generate a plurality of signals. Each of the signals is associated with a different one of the stationary obstacles and has a power level representative of the plurality of parameters associated with the stationary obstacle.

A computer-implemented flight display system including a computer processor that is capable of determining a current energy situation of an aircraft, an electronic display device, and a graphical user interface (GUI) provided on the electronic display device. The GUI includes a current aircraft position symbol, an optimal aircraft position symbol, and at least one symbol indicating a position for changing aircraft configuration. Relative positioning on the GUI of the optimal aircraft position system and the at least one symbol indicating a position for changing aircraft configuration is based at least in part on the determined current energy situation of the aircraft.

A system for assisting in managing the flight of an aircraft in a landing phase. The system comprises a trajectory computation module for determining a trajectory of the aircraft, an interface module and an auxiliary computation module for computing an optimized ground slope, a display unit for allowing an operator to make a selection of the optimized ground slope, and a guidance unit for transmitting guidance orders to controls of the aircraft, the system being configured for the aircraft to follow the optimized ground slope when the latter is selected by the interface module, such that the aircraft reaches a target vertical speed on initiation of the flare phase of the landing.

A method for aiding the landing of an aircraft on a landing runway comprises the following steps implemented automatically by a processing unit: a) acquiring information relating to the runway; b) acquiring information relating to a current situation of the aircraft; i) determining a landing position of the aircraft on a central longitudinal axis of the runway, as a function of a trajectory determined between a current position of the aircraft and this landing position to comply with at least one constraint relating to a roll angle of the aircraft; j) determining a parameter relating to the landing position; k) determining a deviation between this parameter and a reference value; l) comparing this deviation with a predetermined threshold; and m) as a function of the result of the comparison carried out in step l), commanding, if appropriate, the signaling of an alert via the signaling system of the aircraft.
