    [0001] The present invention relates to a system for displaying an aircraft, comprising: - a display ; a set of display generation on the display. Such a system is intended to be installed in the cockpit of an aircraft, to be associated with a cockpit display. The display is for example a display at least partially transparent, such as a semi-transparent screen placed in front of a windshield of the cockpit, an image projection system on the windshield of the cockpit, a semi-sun visor. transparent, a helmet viewfinder, or a semi-transparent bezel close Alternately, the display is a head-down screen integrated into the dashboard of the cockpit. The display system is intended to facilitate the piloting of the aircraft during a landing in conditions of low visibility or zero. Under such conditions, guidance systems allow the pilot to approach closer to the runway. Nevertheless, the landing is only possible when the pilot actually sees the runway. In all cases, at the end of the approach, the pilot visually seeks to locate the position of the airstrip, in order to make the decision to land, or on the contrary to perform a go-around maneuver. To facilitate the identification of the runway threshold in low visibility conditions, modern aerodromes are equipped with approach light booms, located longitudinally in front of the runway threshold.
    [0002] These ramps generally comprise at least one longitudinal line of lamps aligned along the runway axis, and perpendicular to the longitudinal line, at least one transverse line of lamps crossing the longitudinal line. In approach with low visibility, the pilot therefore seeks to first identify the presence of the light ramp approach.
    [0003] This search can be tedious. The pilot must in fact repeatedly control the flight parameters to ensure that the slope and speed of the aircraft are adequate during the descent, and simultaneously locate the area in which he expects to find a light ramp and determine if he sees the ramp in that area. If he does not see the ramp, he must again control the flight parameters, and again determine the possible presence of the light ramp. The comings and goings between these different tasks punctually lead to a heavy workload for the crew. An object of the invention is therefore to have a display system which facilitates the work of the pilot to identify the runway during an approach in low visibility conditions. To this end, the subject of the invention is a system of the aforementioned type, characterized in that the display generation assembly is suitable for displaying, in approach to a landing strip, a location marking of a zone of presence of a light ramp of approach towards the airstrip.
    [0004] The system according to the invention may comprise one or more of the following characteristics, taken in isolation or in any technically possible combination: the location marking comprises at least one lateral location symbol of the presence zone of the light ramp approach; The location marking comprises at least two opposite symbols of lateral location of the presence zone of the approach light ramp, delimiting on the left and right the presence zone of the approach light ramp; the location marking comprises at least one sequence of lateral location symbols on one side of the presence zone of the approach light ramp, the sequence of lateral location symbols converging towards a longitudinal axis of the tracking runway; landing; the location marking comprises two suites of lateral locating symbols respectively delimiting the left and right sides of the presence zone of the approach light ramp; The location marking comprises at least one symbol identifying on the display a position corresponding to a predetermined ground distance from the runway threshold at which the approach light ramp comprises a transverse line of lamps; the predetermined distance from the ground is between 275 m and 335 m; The location marking comprises two opposing symbols situated at a position corresponding to a predetermined ground distance from the runway threshold at which the approach light ramp comprises a transverse line of lamps, the lateral spacing between the opposite symbols corresponding to a distance to the ground strictly greater than the width of the transverse line; 3038047 3 - the display generation assembly is capable of displaying a marking of the position of the landing runway, located above the location marking of the zone of presence of a light ramp approaching the runway landing; the display generation assembly is capable of displaying a track axis symbol, located below the location marking of the presence zone of a light ramp approaching the landing runway; it comprises a database of approach ramps, containing at least one characteristic information of each approach ramp associated with an airstrip targeted by the aircraft, the display generation assembly being specific to the approach ramp; generate and display the location marking using at least one information characteristic of the approach ramp approached by the aircraft contained in the approach ramp database; the display generation assembly is capable of dynamically displaying on the display at least one horizon line and one slope scale with respect to the horizon line; the display generation assembly is capable of displaying, before the display of the location marking of the presence zone of an approaching light ramp towards the landing runway, an identification symbol of the runway; landing, pointing to the position of the runway on the display; The display is an at least partially transparent display, such as a semi-transparent screen placed in front of a windshield of the cockpit, an image projection system on the windshield of the cockpit, a semi-sun visor; transparent, a helmet viewfinder, or a semi-transparent bezel close to the eye. The invention also relates to a display method in an aircraft, comprising the following steps: providing a system as described above; when approaching an airstrip, displaying, by the display generation assembly, a location marking of an area of presence of a light ramp approaching the landing runway.
    [0005] The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the appended drawings, in which: FIG. 1 is a diagrammatic view of a first system; displaying an aircraft according to the invention; FIG. 2 schematically illustrates the cockpit of an aircraft comprising the first display system; FIGS. 3 to 4 illustrate the display generated by the display system when approaching the aircraft to an airstrip; FIGS. 5 to 8 illustrate, in plan view, several configurations of light ramps for approaching landing strips; FIG. 9 illustrates the display generated by a variant of the display system, before the aircraft approaches the landing runway; - Figure 10 is a view similar to Figure 5 illustrating a variant of geographical area containing the approach ramp. A first system 10 for displaying an aircraft according to the invention is illustrated schematically in FIGS. 1 and 2. This system 10 is intended to be installed in an aircraft 12, visible schematically in FIG. display of information on a display in the cockpit 14 of the aircraft, shown schematically in FIG. 2. The system 10 is intended to assist the pilot of the aircraft 12 during an approach phase 15, in the vicinity of an airstrip 13, shown schematically in FIG. 5. In particular, the system 10 is intended to assist the pilot in the visual identification of an approach light ramp 15 to the landing runway 13 since the 14, in order to take the decision whether or not to continue the landing on the landing runway 13. In general, with reference to FIGS. 5 to 8, the approach light ramp 15 extends to the front of runway 13, in the axis A-A 'thereof. It comprises at least one axial line 16 of lamps materializing the track axis A-A ', and at least one transverse line 17A to 17E of lamps, perpendicular to the axial line 16, intersecting the axial line 16 and extending on either side of the axial line 16. The axial line 16 extends from the runway threshold 18, over an axial distance, taken from the runway threshold 18, greater than 426 m (1400 feet), and typically between 426 m and 1067 m (3500 feet). The transverse lines 17A to 17E are spaced longitudinally from each other. Preferably, at least one transverse line 17B extends transversely at a distance of between 274 m (900 feet) and 335 m (1100 feet) from the runway threshold 18, preferably 300 m (1000 feet) from the runway threshold. 18. Non-exhaustive examples of current approach ramps will be described successively with reference to FIGS. 5 to 8.
    [0006] In the example shown in FIG. 5, the width of the axial line 16, resulting from the number of lamps which compose it, decreases as it approaches the threshold of track 18.
    [0007] In the example shown in FIG. 5, the transverse lines 17A to 17E are spaced longitudinally from each other at least 150 m (500 feet). The width of the transverse lines 17A to 17E decreases while approaching the threshold of track 18.
    [0008] The width of the line 17B is for example between 10 m (33 feet) and 60 m (197 feet). In a variant of the approach light ramp 15, shown in FIG. 6, the ramp 15 comprises a transverse line 17F located at the runway threshold 18, and two longitudinal lines 16B, 16C parallel to the axial line 16, connecting the 10 free ends of the transverse lines 17F, 17A, 17B between them, left and right of the axial line 16. As for the ramp 15 shown in Figure 5, the ramp 15 shown in Figure 6 has a transverse line 17B which extends transversely at a distance of between 274 m (900 feet) and 335 m (1100 feet) from runway threshold 18, preferably 300 m (1000 feet) from runway threshold 18. Ramp 15 shown on FIG. FIG. 7 comprises an axial line 16 which widens as it approaches runway threshold 18. It comprises a transverse line 17F located at the runway threshold 18, and a transverse line 17B extending transversely at a distance between 274 m (900 feet) and 335 m (1100 feet) from the runway threshold 18, preferably 300 m (1000 feet) from the runway threshold 18. It does not include other transverse lines. The ramp 15 shown in Figure 8 differs from that shown in Figure 7 by the presence of two longitudinal lines 16B, 16C as described above, and a transverse line 17A located between the lines 17B and 17F.
    [0009] Referring to FIG. 2, the cockpit 14 is provided with a main display system 22 connected to an avionics central unit 20. The main system 22 allows the crew to pilot the aircraft 12, to manage its navigation, to monitor and control the various functional systems present in the aircraft 12. The system 22 comprises a dashboard provided with a plurality of base screens 24A to 24D forming head-down displays. In this example the cockpit 14 is also advantageously provided with at least one semi-transparent head-up screen 26, placed facing the windshield, or even two semi-transparent head-up screens 26. The cockpit 14 is also equipped with a control member 28 for controlling the aircraft, such as a joystick or a stick.
    [0010] In known manner, the base screens 24A and 24C are, for example, primary display screens for displaying flight parameters of the aircraft. The basic screens 24B and 24D are, for example, multifunctional navigation and / or monitoring and control screens for avionics systems.
    [0011] The main display system 22 is provided with a display generation assembly (not shown) adapted to display the different windows present on these screens 24A to 24D. The avionics central unit 20 is connected to a system 30 of sensors for measuring aircraft parameters and for spatial positioning of the aircraft 12.
    [0012] The measurement sensor system 30 comprises, for example, sensors for measuring parameters outside the aircraft such as temperature, pressure or speed, sensors for measuring parameters internal to the aircraft and to its various functional systems. and positioning sensors, such as geographical position sensors, in particular a GPS sensor, sensors for determining the slope of the aircraft, in particular at least one inertial unit, and a sensor for determining a height by ground ratio, including a radio altimeter. The sensors of the measuring sensor system 30 are able to provide information on the geographical position of the aircraft 12, on its speed, heading and attitude (longitudinal attitude, roll angle).
    [0013] With reference to FIG. 1, the display system 10 according to the invention is connected to the measurement and positioning system 30. The display system 10 comprises at least one display 36, and a display generation assembly 38 on the display 36, connected to the display 36 and the measurement sensor system 30. 40. The display 36 is for example one of the screens 24A to 24B or / and is the semitransparent semitransparent screen 26 of the cockpit 14. In other variants, the display 36 is for example a system image projection on the windshield of the cockpit, a semi-transparent sun visor, a helmet viewfinder or semi-transparent bezel close to the eye.
    [0014] The display 36 allows the pilot to observe by transparency the space located at the front of the aircraft 12 and simultaneously, a display generated by the display generation assembly 38. In a first embodiment, which will be described later, the display 36 of the display system 10 according to the invention is the semi-transparent head-up screen 26 of the cockpit 14.
    [0015] The display generating assembly 38 comprises at least one processor 42 and at least one memory 44 containing a plurality of software modules adapted to be executed by the processor 42. It comprises a database 46 of track characteristics. landing, for example stored in the memory 44.
    [0016] The display generating assembly 38 includes a module 48 for recovering data from the measurement sensors of the system 30, in particular the geographical position of the aircraft 12 relative to the ground. With reference to FIGS. 1 and 3, the display generation assembly 38 comprises a module 47 for generating a symbol 49 of the aircraft model, a module 50 for generating a line 52 of artificial horizon , and an associated module 54 for generating a slope scale 56. The display generation assembly 38 also comprises a module 58 for generating a speed vector symbol 60 and modules (not shown) for generating a speed scale. other symbols representative of flight parameters, for example an altitude indicator, warning indicators, vertical speed, ground speed of the engine information, and buoyancy conformation of the aircraft. The display generation assembly 38 further comprises a module 62 for generating a marking 64 for locating the landing runway 13, and a module 66 for generating a runway center symbol 68, the marking 64 and the symbol 68 being suitable for displaying on approach to the landing runway 13, advantageously once the landing runway 13 has been selected by the pilot. According to the invention, the display generating assembly 38 also comprises a generation module 70 for a marking 72 for locating an area 74 for the presence of an approach light ramp 15 towards the landing runway 13.
    [0017] The generation module 47 is able to generate the display of a plane model symbol 49 which materializes a projection at infinity of the longitudinal axis of the aircraft 12, from the data received from the sensors of the aircraft system. Positioning 30. The generation module 50 is able to determine, from the data received from the sensors of the positioning system 30, the position of an artificial horizon line 52 relative to the current attitude of the aircraft. This skyline 52 is straight when the aircraft 12 evolves wings flat, and tilts depending on the heeling angle of the aircraft 12. The module 58 is able to generate the display of a symbol velocity vector 60 indicating the direction of the velocity vector of the aircraft 12, on the basis of the data received from the sensors of the measuring system 30. The vertical deviation between the artificial horizon line 52, away from the deformed region 70, represents the ground slope of the aircraft 12.
    [0018] The generation module 54 is able to display a slope scale 56 located on either side of the speed vector symbol 60 and represented by graduations illustrating successive degrees of slope. The generation module 62 is capable of generating at least one runway localization marking 64 embodying the geographical position of the runway 13, during a landing approach phase, when the runway 13 is likely to be visible at the front of the aircraft 12. This display can be done when the pilot has selected the target airstrip. It is displayed for example when the aircraft 12 is at a height of less than 365 m 10 (1200 feet) and is at a distance of less than 9.3 km (5 nautical miles) from the threshold 18 of the airstrip. 13. The runway location marking 64 comprises at least two left and right lateral location symbols 76A, 76B of the position of the runway 13, the position of which is determined from the geographical coordinates of the runway 13 15 contained therein. in the database 46. These symbols 76A, 76B are for example two convergent lines positioned locally on the display 36, to correspond to geographical lines 78A, 78B parallel to the axis of the landing strip 13 on the ground (see Figure 5), located along the edges of the landing strip 13 or at a predefined distance thereof, as obtained from the database 46. The length of the geographical lines 78A, 78B , and as a result, the length the symbol display 76A, 76B corresponds to the geographical length of the landing runway 13, as obtained from the database 46. Optionally, the runway location marking 64 further comprises a runway marker. a symbol 80 for locating the runway threshold and a symbol 82 for end-of-run location, respectively formed by lines connecting the longitudinal ends of the symbols 76A, 76B. The generation module 66 is able to display a symbol 68 illustrating the direction on the display 36 of the track axis A-A ', for example a dashed line, below and away from the position corresponding to the runway threshold 18 on the display 36. The presence zone 74 on the display 36 corresponds to the ground to a predefined geographical zone 88, shown in FIG. 5. The geographical zone 88 contains at least 50%, and preferably totally The geographic zone 88 is, for example, a trapezoid of axis A-A ', with a vertex situated at the threshold of track 18. The opening angle has trapezium, taken from a target touch point 89 is set so that the width of geographic area 88, taken between 274 m (900 feet) and 335 meters (1100 feet) from the threshold of runway 18, is greater than the maximum width of a 17B transverse line located at this distance, with a margin of accuracy of display. The accuracy margin of display is determined according to the inaccuracy of the positioning of the track, the inaccuracy of the data of the aircraft sensors (position of the aircraft and attitude, in particular the heading), and inaccuracy. on the viewing direction through the display 36. This margin is chosen to ensure that the transverse line 17B remains in the geographical area 88, even when errors are present.
    [0019] Typically, for errors causing a 0.5 ° offset in heading between the calculated axis of the track and the real axis, the margin is about 15 m on each side, or 30 m. The width of the geographical area at the level of the transverse line 17B is preferably greater than 60 m and between 60 m and 100 m. The touchdown point 89 is generally located about 300 m (1000 feet) ahead of the runway threshold 18. Such a geographic area 88 contains most of the existing approach ramps. The location marking 72 on the display 36 comprises at least one 90A symbol at 90F for lateral location of the presence zone 74.
    [0020] In this example, the location marking 72 comprises at least one 90A left side location symbol 90A and the presence zone 74 and at least one right side location 90D 90F symbol of the presence area 74. Each symbol 90A to 90F is here formed by a horizontal line. The location mark 72 here comprises a first series of left side location symbols 90A to 900 spaced longitudinally apart and a second series of right side locating symbols 90D to 90E spaced longitudinally from each other. The left side locating symbols 90A to 90C and the right side locating symbols 90D to 90E converge to the track axis AA 'as they approach the runway 13. The position of each side locator symbol 90A to 90F on the screen corresponds respectively to a geographical point 92E to 92F on the sides of the geographical zone 88, located at a predetermined distance D1 to D3 of the threshold of the track 18. Advantageously, at least one geographical point 92A located to the left of the Geographical area 88 and geographical point 92D located to the right of geographic area 3038047 are placed at a distance from runway threshold 18 corresponding to the presence of a transverse line 17B of lamps. Thus, the lateral location symbols 90A and 90D generated by the module 70 and respectively corresponding to the geographical points 92A, 92D are able to be displayed on the display 36 on either side of the position where the transverse line will appear. 17B lamps. Preferably, the lateral location symbols 90A and 90D respectively correspond to a geographic point 92A situated to the left of the geographical zone 88 and to a geographical point 92D located to the right of the geographical zone 88, which are placed at an axial distance D1 the runway threshold, taken along the AA 'axis between 900 feet and 335 meters (1100 feet), to correspond to a 17B lamp transverse line on most of the approach light strips; existing. The geographical distance transversely separating the geographical points 92A, 92D is then between 30 m and 100 m with the margin of precision of display 15 described above. In the example shown in FIG. 3, at least two left and right lateral location symbols 90C, 90F respectively correspond to a geographical point 92C situated to the left of geographical zone 88 and to a geographic point 92F located to the right of the zone 88 which are placed at an axial distance D3 from the runway threshold, taken along the A-A 'axis, greater than 610 m (2000 feet), and generally between 610 m and 1067 m (3500 feet) to substantially correspond to the axial end of the line 16, and thus encompass substantially the entire ramp 15. In addition, two left and right lateral location symbols 90B and 90E respectively correspond to a geographical point 92B located to the left of the zone 25 88 and at least one geographical point 92E situated to the right of geographic area 88 which are placed at an axial distance D2 from the runway threshold, taken along the axis A-A 'between axial ratio D1 and the axial distance D3, for example at a distance substantially equal to 6 cm (2000 feet). The definition of the geographical zone 88 thus obtained and its delimitation by the predefined geographical points 92A to 92F generates location symbols 90A to 90F which delimit the location zone 76 in a sufficiently precise manner on the display 36 to encompass most of the existing approach ramp structures to be visualized by the pilot. In addition, the symbol 68 illustrating the direction of the track axis AA 'is placed by the generating module 66 below the presence zone 74, vertically under the symbols 90A to 90F, so as not to interfere with the area of presence 74.
    [0021] The operation of the display system 10 according to the invention, when approaching a landing runway 13 will now be described, with reference to FIGS. 3 to 4. Initially, the aircraft 12 descends towards the runway 13. As shown in FIG. 3, the generation module 50 generates the display of the horizon line 52.
    [0022] The generation module 54 generates the display of a slope scale 56 and the generation module 58 generates the display of a speed vector symbol 60 whose vertical distance to the horizon line 52 reflects the plane slope. on the slope scale 56. At a given distance from the landing runway 13, the pilot selects the chosen landing runway 13. When the distance is less than a given display distance, for example 9.6 km (5 nautical miles) and / or at a given display height, for example 365 m (1200 feet), the generation module 62 activates the display of the track location marking 64. It interrogates the database 46 to determine the geographical location of the lines 78A, 78B and transcribes this geographical position to a corresponding position on the display 36 to display the lateral lines 76A, 76B. The generation module 66 determines the geographical position of the track axis AA 'and accordingly calculates the position on the screen of the runway center symbol 68, in the extension of the runway location marking 64, to the gap and below it.
    [0023] The generation module 70 then activates the location marking 72 of the presence area 74. In the example shown in FIGS. 3 and 5, the generation module 70 calculates in real time the geographical position of the geographical zone 88 at from the geographical position of the runway threshold 18, the position of the target touch point 89 and 25 of the width of the geographical zone 88 at a given distance from the runway threshold 18, for example between 274 m (900 feet) and 335 m (1100 feet) from the runway threshold 18 along the A-A 'axis. It then determines the geographical position of the geographical points 92A to 92F from the axial position of the track threshold 18 on the track axis A-A 'and predetermined distances D1 to D3. It transcribes in real time this geographical position into a position on the display 36 and displays each location symbol 90A to 90F on the display 36 at a position corresponding to the geographical position 92A to 92F. The presence zone 74 of the approach light ramp 15 is thus physically defined on the display 36 being delimited laterally by the symbols 90A to 90F.
    [0024] In the example illustrated in FIG. 3, the cloud layer obscures the approach ramp 15. The pilot can, however, in real time anticipate where the approach light ramp 15 will appear and focus his search only on an area 74. on the display 36 being guided towards this zone 74 by the presence of the location marking 72. In particular, the pilot can consult an approach chart associated with the runway 13 to determine the type of ramp associated with the landing runway 13 referred to. He can anticipate that a transverse line 17B of lamps will appear between the locator symbols 90A, 90D, and that the remainder of the approach light ramp 15 will be located longitudinally between the symbols 90A through 90C on one side and between the symbols 90D to 90F, on the other hand. This is illustrated in FIG. 4, once the cloud layer is pierced, the approach light ramp 15 appears in the presence zone 74 inside the location marking 72.
    [0025] The presence of the location marking 72 thus greatly simplifies the pilot's task and reduces his workload, since he knows precisely where to look for the approach ramp 15 at the front of the aircraft 12, in order to take the whether or not to land on the runway 13. In a variant, the lateral locating symbols 90A to 90F are not formed by horizontal lines, but by other symbols such as vertical lines, crosses geometric shapes such as polygons. In another variant, the location marking 72 comprises, in substitution or in addition to the previously mentioned discrete lateral locating symbols 90A to 90F, lateral locating symbols formed by lateral locating lines, whose position on the screen corresponds to the lateral edges of the geographical zone 88 visible in FIG. 5. In another variant visible in FIG. 10, the geographical zone 88 does not have a trapezoidal shape, but has another polygonal shape, in particular a rectangular shape with lines parallel to track 13 or a shape with curved edges (not shown). The display of the lateral location symbols 90A to 90F is then modified to correspond to the edges of the geographical zone 88. In a variant illustrated by FIG. 1 (in dotted lines) and in FIG. 9, the display generation assembly 38 comprises a module 96 for generating an identification symbol 98 for identifying the landing runway 13, pointing to the position of the landing runway 13, capable of generating and displaying the symbol 98 before the display of the 3038047 13 marking runway location 64 and the location marking 72 of the presence zone 74 of an approach ramp 15. With reference to FIG. 9, the identification symbol of the landing runway 13 comprises, for example a cartridge 100 containing an identification information 102 of the landing runway 13 and a line 104 pointing to the position of the runway 13 from the cartridge 100. The identification information 102 of the runway landing 13 is for example the number of the runway, obtained from the database 46 of airstrips 13.
    [0026] In operation, the generation module 96 is able to activate the display of the symbol 98, preferably when the dimensions of the landing runway 13 on the display 36 are too small to display the runway location marking 64. In a variant, the display system 10 comprises a database of approach ramps 15, advantageously contained in the memory 44, containing information relating to the characteristics of the ramps associated with each landing strip 13 on which the aircraft 12 is likely to land. The information is for example the maximum length of the ramp 15, in particular of its longitudinal line or lines 16, the position and / or the width of the or each transverse line 17A to 17E, etc.
    [0027] The generation module 70 is then able to interrogate the database 200 in approach of a given track 13 to calculate the dimensions of the geographic area 88 and the geographical position 92A to 92F corresponding to each delimiting symbol 90A to 90F in front of displayed according to at least one characteristic information of the approach ramp 15 from the database 200.
    [0028] In particular, the generation module 70 is able to determine the position of the points 92C, 92F corresponding to the axial end of the line 16, and from the length of the ramp 15 loaded into the database 200. another variant, the display 36 is a head-down screen connected to an optical sensor for observing the space at the front of the aircraft 12.
    [0029] In one variant, the system 10 does not necessarily display a horizon line and / or a slope scale, but just the location marking 72.
