Definitions
- a method of presenting anti-collision information in an aircraft head-up display is described.
- the field of the invention is that of flight management systems for aircraft comprising an anti-collision system and a coilimated display device that can have symbologies dedicated to obstacle avoidance.
- flight there are two types of collision possible.
- the aircraft can either hit the ground or another aircraft that is part of the air traffic.
- the aviation industry is focusing its efforts on reducing and eventually eliminating all future accidents related to these collisions.
- GCAS Global System for Mobile Communications
- the “GCAS” system essentially consists of a connected central electronic calculator on the one hand to the network of sensors and sensors of the aircraft and on the other hand to the various visualizations of the dashboard and the audible alarms arranged in the cockpit, by means of a data transmission bus.
- the sensors are essentially sensors for determining the position of the device relative to the ground, its attitude and speed.
- the visualizations concerned are the Head-up Viewfinder as well as the Pilot and Navigation Headsheets such as "Dispiay Navigation” and “Primary Flight Displays", screens marked “HUD”, "ND” and "PFD”.
- T-CAS Traffic alert and collision avoidance System
- the "T-CAS" systems comprise at least one transponder, data processing means received and at least one visualization means.
- An aircraft transponder is an on-board system that transmits a message about the aircraft when it receives a polling message.
- the message generally includes an identification code of the device as well as more or less detailed information on the position of the device.
- the "TCAS” function is integrated in the navigation screen, also called “Navigation Dispiay” or ND.
- the "TCAS" system distinguishes two regions: a first region within which another aircraft may represent a risk of collision. If an aircraft appears in this region and represents a potential danger of collision, a traffic notification is issued by the device called "Traffic Advisory" or "TA".
- the latter informs the pilot that another aircraft is nearby but does not suggest an avoidance maneuver.
- the second region is located in the immediate vicinity of the aircraft. In this case, if an aircraft appears in this region, the situation has worsened and the collision seems imminent, an audio message and a visual alert are produced by the device called "Resolution Advisory" or "RA”, indicating the aircraft concerned and signaling the action to be performed by the pilot, namely to maintain the current trajectory, either to go up or down or to monitor the vertical speed.
- the system is designed so that the "TCAS" of the other aircraft advises another maneuver. Often, the "TCAS" indicates the first aircraft to climb and the second aircraft to go down, which greatly increases the separation between the two aircraft. When the alert is complete, the system announces the end of the conflict.
- a voice command set message that can be for example "PULL-UP” which means “MONTE” in case of alarm “GCAS” or "CLI MB-CLI MB” which means "GRIMPE-
- a display of the set point on the "PFD” screen for example a "PULL-UP” message in case of "GCAS” alarm, or one to two red zones to avoid, and a green zone to place the corresponding needle on the screen.
- the vertical speed of the device in case of alarm
- TAA calculated by the "TAWS” which is superimposed on the area "THD” already present and possibly a cartographic background on the most recent aircraft.
- This 2.5D map background represents the terrain overflown, the relief being represented in the form of shading.
- TCAS alarm of the threatening aircraft display in amber or red depending on whether the alert level is of the "TA” or "RA” type.
- the aircraft has a head-up viewfinder, it typically displays information relating to driving or navigation. In a head-up viewfinder, this information is collimated to infinity and projected onto the outside landscape. An example of this type of figuration is shown in Figure 1. The pilot therefore simultaneously sees a projected symbology and the "real world" located outside the device.
- the outer rectangle represents the limits of the field of view of the viewfinder.
- a scale 1 altitude in feet we find classically on the right of Figure 2 a scale 1 altitude in feet, left a scale 2 speed in knots, in the center, the horizon 3, the flight director 4 and at the bottom of Figure 2 the rosé caps 5 with the indication of the path to follow, better known by the term "HSI", meaning "Horizontal Situation Indicator”.
- HSUMI Horizontal Situation Indicator
- the purpose of the method for managing an anti-collision system for an aircraft according to the invention is to enable the pilot to control, in the event of an "GCAS” or “TCAS” alarm, the position of the carrier with respect to the threat in question. at the same time that it follows a guidance symbology at the head. For this, we enrich the presentation of guidance information head-up alarms "GCAS” or “TCAS” by the danger information, better known as "situation awareness”.
- the subject of the invention is a method for managing an anti-collision system for an aircraft, said system comprising means for detecting a collision with a threat and at least one device head-up display device, said device comprising means for generating, coimimating and superimposing symbols on the external landscape intended to assist in piloting said first aircraft in the horizontal and vertical planes, characterized in that the symbology comprises two modes of display dedicated to collision detection that are:
- the symbology comprises at least one symbol representative of the limits of the escape path of the aircraft to avoid the collision and allowing the pilot to engage his avoidance maneuver;
- Control mode this mode is displayed when the avoidance maneuver is engaged and the collision avoided, the symbology includes at least the symbol representing the limits of the escape path of the aircraft and a view from above representing the airspace around it of the aircraft and having at least one representation of the threat.
- the system is of the anti-collision system type with the terrain, the threat being the terrain around the aircraft, that the symbol representing the limits of the escape path includes a horizontal bar representative of the minimum slope necessary to the aircraft to succeed in its avoidance maneuver.
- the symbol representing the limits of the clearance path comprises two identical vertical parallel bars of angular dimension substantially equal to the vertical angular field of the Header display device, the positions of said bars in the horizontal plane being representative of the limits of the path of clearance of the aircraft, the horizontal bar being limited by these two vertical bars so as to form a large H in the field of the head-up display device.
- the top view represents the portion of land representing a threat, the portion of land is then represented by two zones, a first imminent danger zone represented by a first luminance level, a second danger zone. in the medium term represented by a second luminance level substantially lower than the first luminance level. These two areas correspond to bright red and bright yellow areas of the TAA displayed on the ND.
- the system is of the anti-collision system type with the air traffic, the threat being a second aircraft
- the symbol representing the limits of the escape path includes a rectangle representative of the area in which the aircraft must be located. engage to succeed his avoidance maneuver.
- the rectangle is extended by two slashes attached either to the two high points of the rectangle, or to the two lower points of the rectangle.
- the top view then comprises a circle graduated to a known scale, centered on the first aircraft and a representation within said circle of its relative position of the second aircraft, said representation of the second aircraft possibly being a geometric figure substantially of square shape and includes an indication of the relative altitude of the second aircraft relative to the first aircraft and a trend arrow indicating whether the second aircraft is ascending or descending.
- the symbology does not include any of the caps, also called "HSI”.
- FIGS. 2 and 3 represent the evolution of the symbology according to the invention as a function of the imminence of the danger in the case of a "GCAS" system;
- FIGS. 4 and 5 represent the evolution of the symbology according to the invention as a function of the imminence of the danger in the case of a "TCAS" system.
- HUD situation awareness data represented by a top view of a field area in the event of a "GCAS” alarm or traffic threatening in case of "TCAS” alarm.
- the presentation of these data corresponds to the so-called “action-control” scheme that a pilot implements during an alert requiring a change of trajectory.
- An action-control scheme comprises two phases. A first phase called “action” in which the pilot must quickly make a maneuver. A second phase called “control” in which the pilot verifies that the maneuver carried out put his device out of danger.
- FIGS. 2 and 3 represent the evolution of the symbology according to the invention as a function of the imminence of the danger in the case of a "GCAS" system.
- the pink of the caps called “HSI” is removed to lighten the symbology and allow the pilot to concentrate on his maneuver.
- Figure 2 represents the symbology in "action" mode in case of GCAS alert.
- the symbology provides the pilot with a zone in which he must place the speed vector of the aircraft to engage the avoidance maneuver. This area is called “fly ⁇ to-zone".
- the representative symbol of the limits of the clearance path comprises a horizontal bar 1 1 representative of the minimum slope necessary for the aircraft to succeed in its avoidance maneuver and two identical vertical parallel bars 12 of angular dimension substantially equal to vertical angular field of the Header display device, the positions of said bars in the horizontal plane being representative of the limits of the clearance path of the aircraft, the horizontal bar being limited by these two vertical bars so as to form a large H in the field of High Head visualization device or a form in "rugby poles".
- Figure 3 shows the symbology in "control” mode in case of GCAS alert.
- the terrain zone 13 responsible for triggering the alarm represented in top view, namely the "TAA" data from the "TAWS" is presented.
- TDD To simplify the display, we do not display the data called "THD”.
- This symbology is triggered once the velocity vector has passed in the "fly-to-zone”.
- This symbology presented is monochrome, the color of the symbology being green.
- High Head sights are monochrome for several reasons.
- FIGS. 4 and 5 represent the evolution of the symbology according to the invention as a function of the imminence of the danger in the case of a "TCAS" system. During the “action” and “control” phases, the "HSI" caps are also removed.
- Figure 4 represents the symbology in "action” mode in case of "TCAS" alert.
- the symbology presents the pilot with a zone in which he must place the speed vector of the aircraft to engage the avoidance maneuver. This area is called “fly-to-zone".
- the The limits of the escape path include a rectangle 14 representative of the area in which the aircraft must engage to succeed in its avoidance maneuver. This rectangle is extended by two oblique bars attached either to the two lower points of the rectangle indicating the lower limits of the escape path. It is also possible to represent the upper limits of the escape path by two slashes attached either to the two high points of the rectangle.
- Figure 5 represents the symbology in "control” mode in case of "TCAS" alert. This symbology is triggered once the velocity vector has passed in the fly-to-zone.
- a top view 16 which comprises a circle graduated to a known scale, centered on the first aircraft and a representation within the circle of the relative position of the aircraft.
- second aircraft responsible for triggering the alarm namely the data called "FRA” or "TA” without displaying the rest of the surrounding traffic.
- ADSB Automatic Depends Surveillance - Broadcast
- the square is replaced by a chevron giving in addition the course of the threat.
