Definitions
- the invention relates to a method for guiding aircraft on taxiways.
- NLA New Large Aircraft, e.g. Airbus A3XX
- ICAO International Civil Aviation Organization
- ACI Airports Councii International
- the A3XX could safely maneuver on existing taxiways (Taxiways Code E / Group V) approved for B 747, including curves and branches, if the lateral deviation of the main landing gear from the taxiway center line is at most 0.5 m.
- This requires, among other things, a considerable oversteer of the nose landing gear or a control of the nose landing gear along an invisible aircraft-specific ideal line that deviates significantly from the center line
- the required lateral accuracy and driving along an ideal line to be calculated for the nose gear cannot be achieved by manual control by a pilot.
- Navigation systems are known for road vehicles, which include the following components:
- Inertial system autonomous navigation systems based on motion sensors, e.g. wheel rotation measurement and electronic compass
- errors that are generally proportional to the distance traveled since the last base or to the past (gyro systems)
- Satellite navigation system if applicable (due to shadowing and multiple reception of signals from individual satellites in road traffic, can only be used for accuracies in the range of around 100 m) i.a. only to support the inertial system
- the object of the invention is to provide a method for guiding aircraft To create taxiways with the help of which aircraft with a lateral deviation of less than 0.5 m can be guided from an ideal line.
- the next generation large aircraft (New Large Aircraft) should be able to taxi safely on the taxiways that are already available.
- the system for carrying out the method according to the invention has the following components:
- Inertial system customary in aircraft e.g. an inertial navigation system.
- an additional navigation system that is independent of the aircraft e.g. a satellite navigation system can be used. It is also possible to use several navigation systems in parallel.
- the navigation system need only have a limited accuracy (typically 10 m), which alone is not sufficient to achieve the object on which the invention is based.
- - Storage medium with reference information in particular in the form of a digital taxiway map. It contains the exact coordinates of the light exit openings of all fires of the intended taxiways and apron areas suitable as a base. The accuracy of the taxiway map contained coordinates is, for example, approx. 10 cm.
- the measurement should e.g. with an accuracy of approx. 10 cm. Suitable for this are e.g. Video cameras or scanners, which are advantageously arranged on the main landing gear of the aircraft.
- the taxiway to be driven can be selected by input from the pilot (in consultation with the tower) or by data transfer from the tower.
- the detection of the fire by the sensor can be facilitated by only shading the fire of the intended taxiway.
- the method according to the invention is not limited to NLA, but can be used for all aircraft and vehicles that enter areas with lights.
- the degree of automation can be very different and e.g. have the following forms:
- - manual taxiing by the pilot using guidance information generated by the system, e.g. voice output, visible input glare into the outside view (head-up display) or on a monitor, - semi-automatic taxiing with automatic steering and manual longitudinal guidance (accelerate, brake) by the pilot, - automatic taxiing, if necessary with monitoring by the pilot.
- guidance information generated by the system, e.g. voice output, visible input glare into the outside view (head-up display) or on a monitor, - semi-automatic taxiing with automatic steering and manual longitudinal guidance (accelerate, brake) by the pilot, - automatic taxiing, if necessary with monitoring by the pilot.
- FIG. 2 shows the schematic representation of a system for carrying out the method according to the invention.
- the sequence of the method according to the invention is described by way of example with reference to FIG. 2.
- the current position of the aircraft is determined with an accuracy of, for example, 5 m.
- the position of the fire detected by the sensor SEN is determined in the control unit ST and compared with the reference information contained in the digital taxiway map REF.
- the assignment of a detected fire to the corresponding fire on the taxiway map REF is clear if the distance between adjacent fires is greater than the blurring of the navigation system NAV (here, for example, the 5 m mentioned above).
- the position of the detected fire taken from the reference information serves as a base for the navigation system NAV.
- the aircraft is determined with increased accuracy compared to the original position determination of the navigation system.
- the aircraft position can be determined with an accuracy of less than 0.5 m.
- guide information is generated in the FRG unit.
- the pilot reaches a certain position on the

Abstract
L'invention concerne un procédé de guidage d'avions sur des voies de circulation (R) de l'aire de trafic d'un aéroport, des feux de position (FE) étant disposés sur les voies de circulation (R) et éventuellement à d'autres emplacement de l'aire de trafic. Ce procédé comporte les étapes suivantes: détermination de la position actuelle de l'avion, avec une précision définie, au moyen d'un système de navigation (NAV), détection et mesure de la position des feux de position au moyen d'un capteur (SEN) monté sur l'avion; mise à disposition d'informations de référence (REF) avec les positions des différents feux de position (FE); comparaison de la trajectoire suivie par le système de navigation (NAV) avec les informations de référence (REF), et utilisation des feux de position (FE) détectés comme points d'assistance pour le système de navigation (NAV); et, à partir de là, détermination de la position actuelle de l'avion avec une précision élevée par rapport à la détermination de position d'origine du système de navigation (NAV); et génération d'informations de guidage sur la base de la position de l'avion ainsi déterminée.
