Definitions
- the present invention relates to a method and a on-board pilot assistance device in the absence of air traffic control.
- the present invention aims to help the pilot to manage the situation resulting from this absence of air traffic control. Its purpose is to facilitate estimation of a risk of conflict between aircraft in an area evolution, as well as allowing the separation of aircraft. It is of particular interest in regions where ground traffic control is nonexistent or faulty. By conflict is meant too much close proximity of two aircraft operating in the same area; proximity can be understood in terms of distance, altitude and / or route.
- This task is usually performed on the ground and is usually designated by ATC ("Traffic Control "Or” Air Traffic Control ").
- the control can be performed by radar, but can also take place in regions without such equipment. In this case separation of aircraft is governed primarily by assigning aircraft departure times or different altitudes.
- the pilot or crew of an aircraft taxiing in one of these areas must apply procedures specific defined by IATA ("International Air Transport Association ") known as IFBP (" In Flight Broadcast Procedure ”) or TIBA (" Traffic Information Broadcast by Aircraft "). These procedures consist, for each pilot, in broadcasting information on a dedicated radio frequency, defined for this geographic area (for example 126.9 MHz in Africa or 126.95 MHz in South America), at intervals of predefined times (for example every 20 minutes) and during trajectory changes ("waypoints”) or altitude of the aircraft.
- IATA International Air Transport Association
- IFBP In Flight Broadcast Procedure
- TIBA Traffic Information Broadcast by Aircraft
- the pilot must also listen to the information broadcast by other pilots on this same frequency radio and interpret that information.
- the range of the waves radio on the dedicated frequency considered is around 700 to 900 km.
- the pilot therefore receives said information broadcast by pilots of aircraft located in a sphere of about 700 to 900 km radius around it, this which allows him to know the surrounding traffic.
- this communication includes the repetition of the first information, i.e. flight number, altitude and general direction.
- Such communication is normally broadcast by each pilot at repeated intervals, for example 20 minutes. It is also broadcast when the aircraft reaches a given altitude level or during a change in altitude level. Finally, it is broadcast when crossing a "waypoint".
- TCAS Traffic Collision Avoidance System
- the document referenced (1) describes a method of separation of aircraft based on automatic exchange information, directly between aircraft. Setting work of such a process is dependent on requirements such that, for example, a harmonization of protocols automatic exchange between aircraft equipment. It also assumes that the other aircraft are equipped with an appropriate device.
- the object of the present invention is to provide a process and an on-board device for piloting assistance in lack of air traffic control to simplify exploiting blind broadcast data for predict with better precision and better reliability a risk of conflict between two aircraft.
- the pilot not only has data relating to the aircraft in the vicinity when the message from blind diffusion, but also at times intermediaries, when the aircraft in the vicinity occupies intermediate positions between those that have been announced.
- the intermediate positions are certainly positions estimated by calculation and not exact positions but nevertheless allow very good estimated risk of conflict. They allow also to assess this risk well before it occurs. In the absence of a new blind broadcast message, the estimated positions can possibly be extrapolated beyond the second position of the last message received.
- the means of calculation which are, for example, a on-board computer, can be designed to calculate a or several intermediate positions extrapolated or even, preferably to continuously calculate the position extrapolated intermediary of one or more aircraft in the vicinity.
- the concomitant display of the position of the aircraft in the vicinity and of the aircraft equipped with the device of the invention allows the pilot to measure a possible risk of conflict, without having to mind the data transmitted during communication from the last blind broadcast.
- the position of the aircraft equipped with the the invention is obtained by equipment of positioning known per se, such as GPS ("Global Positionning System "), IRS (" Inertial Reference System “or navigation based on information from inertial units), FMS ("Flight management system”), GPIR (navigation according to synthesis of GPS and IRS information (much more precise), radio navigation ...
- GPS Global Positionning System
- IRS Inertial Reference System
- FMS Frequency management system
- GPIR navigation according to synthesis of GPS and IRS information (much more precise)
- radio navigation ...
- the display means may include advantageously a data entry unit and display type MCDU (Multipurpose Control Display Unit), and, concomitantly, a display unit of navigation ("Navigation Display” or ND), primarily devoted to the display of the position and the trajectory current of the aircraft.
- MCDU Multipurpose Control Display Unit
- ND display unit of navigation
- the means of data entry of the messages of blind broadcast can be fitted with a keyboard manual, such as, for example, the alphanumeric keyboard generally associated with known MCDUs.
- the device can also be fitted with an alarm controlled by calculation means, to signal a risk of conflict between the aircraft in the vicinity and the aircraft equipped with the device of the invention.
- the horn can be a buzzer or visual, with an adjustable trigger threshold.
- the device of the invention further includes means for assisting with the entry of the trajectory of an aircraft in the vicinity and / or means of assistance in updating the data of a aircraft in the vicinity.
- the aircraft 10 illustrated in the figure is an aircraft in the vicinity of the aircraft in which the device of the invention. This aircraft 10 moves according to an air route and, in its movement, crosses waypoints referenced. These crossing points are the way-points.
- the pilot of the aircraft in the vicinity 10 transmits on a dedicated frequency, for example 126.9 MHz, informational messages. These are messages from blind diffusion. As mentioned above these messages are broadcast during specific events such as for example passing through a "waypoint" or, by default, every 20 minutes.
- step 12 The receipt of this message by an aircraft is indicated as step 12 in the figure.
- the pilot of this aircraft receives such messages by radio, on this dedicated frequency, from a large number of aircraft which evolve within the transmission range limit of broadcast messages.
- the consideration of these messages includes a filtering step 14, carried out by the pilot, which is to ignore blind broadcast messages from aircraft that are not likely to cross the route of the aircraft in which the pilot is located, or who are separated by too great a distance for one more accurate estimate of conflict risk is either justified.
- the pilot enters relevant data on a keyboard 16, for example an MCDU unit, connected to a on-board computer 18.
- the data entered can contain all the data of the broadcast message blind, or may only include data from first and second flight positions, together with their respective time data. These are, for example, waypoints and passage time indications real or estimated by these "waypoints".
- This on-board computer 18 is provided for calculating, for example in real time, the position of each aircraft in the neighborhood for which the data was entered, that is, the state of the surrounding traffic.
- This on-board computer 18 also receives input position information (latitude, longitude, flight level) from navigation computers.
- This on-board computer 18 therefore determines, by example cyclically, the position of each aircraft surrounding traffic by interpolating information entered beforehand by the pilot, then he presents the calculated positions of different aircraft in the neighborhood and their forecast trajectories on a cockpit screen.
- All aircraft already equipped with MCDU are equipped with FMS including, in the database, the "waypoints" and “airways” of the region overflown with their characteristics and in particular the positions geographic (latitude, longitude).
- a display screen 20, controlled by the computer edge 18 is provided to display, in a form any position of the aircraft in the vicinity obtained by calculation.
- the position of this aircraft in the neighborhood is displayed concomitantly with that of the aircraft equipped with the device of the invention, for allow the pilot to visually perform a estimated risk of conflict.
- Other data such as aircraft routes, waypoints, etc. can possibly be displayed on the same screen.
- the position of each aircraft is displayed as an area 21 within which the presence of this aircraft is considered likely.
- this area 21 can be represented on the screen 20 in the form of a circle whose diameter may depend on the age of the information entered into the computer. The diameter of this circle can especially be higher as these information is old to reflect the interpolation error (increasing over time) of the current position of the aircraft from its position at the instant of receipt of said information and its planned trajectory.
- the radius of such a circle is therefore proportional to an uncertainty of its estimated position.
- the uncertainty includes a fixed component (approximately 20 nautical miles) related to the error on the position data, and a time-dependent component (approximately 2 nautical miles per hour), and which corresponds to a pessimistic drift of position.
- the display on said screen is made of so as to take into account in a complementary way the information provided by this ADS-B equipment and said information entered by the pilot, the latter being then less numerous, which saves time.
- this display makes it possible to distinguish the aircraft whose position is received by this equipment and those whose position is determined according to the invention.
- aircraft are symbolized by a model precisely positioned and oriented by its relative heading.
- the method and the device according to the invention also make it possible to detect a conflict between the trajectory of the aircraft and the trajectory of another aircraft determined both from said information entered by the pilot only from the data obtained with ADS-B equipment.
- Such a potential conflict of trajectories are reported to the pilot, for example in changing the display color on the aircraft screen concerned so as to differentiate it from other aircraft (for example display in amber of the symbol representing this aircraft).
- Estimating a risk of conflict can be made by the pilot, but can also, in a certain measurement, result from the calculation performed by a computer of edge 18.
- Reference 22 designates for this purpose a emergency alarm which is only activated if a risk conflict is detected by this computer 18.
- Alarm signal is triggered only when a certain number of configured conditions are respected.
- a risk of conflict may be signaled if: [(the aircraft levels cross each other broadly) OR (The aircraft are moving on the same level to within X ft)] AND [(the aircraft are on the same air route) OR (the air routes of the aircraft intersect) OR (the air route of the nearby aircraft is unknown) AND (The direct horizontal distance between the two aircraft is less than Y NM)].
- X and Y are thresholds to be adjusted after setting point.
- aircraft levels are cross "means that the aircraft in the vicinity changes level from a current level to a later level and that these two levels regulate the level of the equipped aircraft of the device of the invention.
- the routes displayed on the first page must contain the routes of aircraft in the vicinity to save in the vast majority of cases.
- the pilot must select the "waypoint" of the route that interests him.
- the device the invention proposes a list of "waypoints" on said road. To facilitate selection, the list starts with a so-called reference point chosen according to different criteria, listed below. By default, the pilot is presented with points located on either side of the point of reference, without prejudging the direction of travel of the road.
- the reference chosen is the "waypoint" of the route in question closest to the current position of the aircraft in which the invention.
- the pilot has access to this data on fields traffic review individuals, in the capture.
- the fields describing the reporting points and estimates are replaced by extrapolated data.
- the pilot has information updates, it has the option of either correcting extrapolated information, either to confirm the data extrapolated (a confirmation of the time of passage automatically confirms the associated point).
- the symbol displayed on the navigation screen representing the aircraft in the vicinity, is differentiated depending on whether the position of this aircraft is a position from extrapolated information or a confirmed position by a message from the pilot of this aircraft.

- le filtrage des messages de diffusion aveugle des aéronefs qui ne risquent pas de croiser la route dudit aéronef, ou qui en sont séparés par une distance trop importante pour qu'une estimation plus précise du risque de conflit ne soit justifiée,
- la saisie sur un clavier de données d'au moins un message de diffusion aveugle émis par au moins un aéronef dans le voisinage, le message de diffusion aveugle comprenant au moins une donnée de route de vol, une donnée d'une première position de vol, une première donnée temporelle relative à l'instant auquel la première position de vol est atteinte, une donnée d'une deuxième position de vol, future, et d'une deuxième donnée temporelle estimée, relative à un instant auquel la deuxième position de vol est atteinte,

La vitesse sol peut être obtenue à partir d'une distance séparant les première et deuxième positions de vol de l'aéronef dans le voisinage le long de la route de vol, et d'une durée séparant les première et deuxième données temporelles. On calcule ensuite une position de l'aéronef dans le voisinage sur sa route de vol, en fonction de la première position de vol, de la vitesse sol de vol et d'une indication temporelle courante. L'indication temporelle courante est, par exemple, l'heure courante ou le temps écoulé depuis la première indication temporelle.Le calcul de la position extrapolée peut être un calcul discret et ponctuel. Il peut aussi être effectué de façon continue, par exemple pour un affichage dynamique de l'évolution de la position des aéronefs dans le voisinage.Dans une mise en oeuvre particulière du procédé de l'invention, on peut en outre comparer la position extrapolée actuelle de l'aéronef dans le voisinage à une position actuelle de l'aéronef dans lequel le procédé est mis en oeuvre. Ceci permet de déclencher une signalisation lorsque la composante verticale et la composante horizontale de la distance entre ces positions sont respectivement inférieures à des consignes déterminées.Il s'agit là d'une disposition permettant de signaler l'approche d'un risque de conflit.Dans le calcul des composantes verticale et horizontale de la distance entre les positions des aéronefs, une donnée de leur altitude peut également être prise en compte.

- le pilote n'est pas obligé de frapper les caractères du nom de l'"airway",
- le pilote peut avoir oublié le nom de l'"airway" entendu sur la fréquence dédiée, ou ne pas l'avoir bien entendu, ou avoir un doute sur son orthographe.
- Le pilote n'est pas obligé de frapper les caractères du nom du "waypoint".
- Le pilote peut avoir oublié le nom du "waypoint" entendu sur la fréquence dédiée, ou ne pas l'avoir bien entendu, ou avoir un doute sur son orthographe. Comme pour le report de position, le pilote doit renseigner trois données définissant la position estimée. Considérant qu'il y a une forte probabilité que cette estimée soit sur la même route que le report, la fonction préjuge de la route et renseigne par défaut le champ "airway" par celle du report.

Pour faciliter la sélection, la liste part du point de report. On présente par défaut au pilote les points situés d'un coté et de l'autre du point de report, sans préjuger du sens de défilement de la route.
