摘要:
The guidance device of the aircraft includes a unit for constructing a flight trajectory of the aircraft, which adapts the height of the flight trajectory to a downstream relief so as to allow the aircraft to clear this downstream relief by implementing a rectilinear climb at maximum rate of climb of the aircraft, along a rectilinear lateral direction corresponding to the direction of the aircraft at the moment of the triggering of the maneuver.

Methods and systems for planning, managing, and executing the flight path of an unmanned aerial vehicle are disclosed. In particular, the methods and systems are designed to reduce the likelihood that the UAV will be detected by determining a flight path based on the proximity of the UAV to a point of interest and the visual, acoustic, and infrared signatures of the UAV relative to a point of interest. Additionally, the methods and systems enable a UAV operator to compare a recommend flight path and an altered flight path based on how the altered flight path changes the proximity of the UAV to a point of interest, and changes the visual, acoustic, and infrared signatures of the UAV relative to a point of interest.

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.

The device (1) comprises a screen (13) which simultaneously displays a sign representing a selected setpoint value relating to a height parameter which is used during the phase of flight, and a sign illustrating a corresponding value which is representative of an estimated positional error.

The invention concerns a system (1) comprising guiding means (3) which, when guiding the aircraft along a low-altitude flight path, and upon a climb command, continue guiding the aircraft along the lateral path of said low-altitude flight path, and subject the aircraft in the vertical plane to a climb along a climb gradient which is not less than a maximum gradient of said flight path.
摘要:
A method and device for ensuring the safety of a low-altitude flight of an aircraft is disclosed, wherein low-altitude flight is flight along a flight trajectory at low altitude, for example 500 feet, that allows an aircraft to follow as closely as possible the terrain being over-flown. To avoid collision with the terrain, a safety corridor, devoid of any obstacle, is determined which is delimited on either side of the lateral trajectory, and whose width depends on a global uncertainty, and the aircraft is guided along the flight trajectory, avoiding any exit of the aircraft from the safety corridor.

The invention concerns a terrain avoidance method and system for an aircraft. The system comprises a collision alarm device (3) and an auto-pilot device (5) including means (7) for determining a climbing order with optimal slope for the aircraft, means (12) for checking whether a first altitude gain at the relief, by applying the optimal slope climbing order, is sufficient for clearing said relief, means (11) for finding if there exists at least one heading variation value, for which the corresponding altitude gain is sufficient to clear the relief, and means (17, 22) for applying to the aircraft, if the first altitude gain is sufficient, an optimal slope climbing order with an order to maintain the current heading and, if the first altitude gain is insufficient, a particular climbing order sufficient to clear the relief, with a heading order which corresponds to the selected heading variation value.

The inventive device (1) comprises: means (3) which can be used by an operator in order to enter a plurality of errors which each have an impact on the automatic low-altitude flight of the aircraft; means (4) for determining an excursion probability of a safety corridor that is not to be crossed; and means (5) for determining the width of said safety corridor form the aforementioned errors and excursion probability, taking account of at least one mathematical expression linking at least the errors, the excursion probability and the width.
摘要:
A method of automatically guiding an aircraft for flight at low altitude determines an LLF (low level flight) trajectory section for following terrain to be overflown by the aircraft. The LLF trajectory section takes account of predictions of the aircraft's mass and speed and climb and descent performance. The LLF trajectory section includes an entry point and an exit point. The LLF trajectory section is integrated between a first trajectory part corresponding to a first phase of flight and a second trajectory part corresponding to a second phase of flight, by providing respectively first and second transition phases. The aircraft is automatically guided so that it successively captures, follows, and leaves the LLF trajectory section.
