Abstract: The invention relates to a flight guidance system for the flight support of a aircraft (1), said system comprising a plurality of fixed ground stations (4a to 4e) respectively comprising a transmitting and/or receiving unit (5a to 5e), and at least one transmitting and/or receiving unit (6) that is arranged on the aircraft (1), the transmitting units being act up to send position signals (7) and the receiving units being set up to receive said position signals (7).

Abstract: A control device is provided for an aircraft, the aircraft having at least one undercarriage with one or more undercarriage wheels. A control mechanism interacts with the aircraft undercarriage and is configured to turn the undercarriage wheels relative to the longitudinal axis of the aircraft. The control device has an alignment unit which is connected to the control mechanism and which is configured to control the turning of the undercarriage wheels by means of the control mechanism during at least one part of the landing or take-off phase of the aircraft in such a way that the running direction of the undercarriage wheels is aligned in the direction of a fixed point which may be a corrected fixed point situated below a fixed point by a compensation angle.

Abstract: The invention relates to a device (10) for stabilizing the guidance of a vehicle (1), the vehicle (1) having at least one or two which is arranged in such a way that it can be turned relative to the longitudinal axis of the vehicle (1), and steering means that interact with the at least one wheel (2) and are designed to guide the vehicle (1) by turning the at least one wheel (2). The device (10) has a detecting unit (12), which is designed to detect an at least partial transition from static friction to dynamic friction between the at least one wheel (2) and a ground covering (3), and furthermore has a control unit (11), which, when the detecting unit (12) detects the transition from static friction to dynamic friction, is designed to turn the at least one wheel (2) by means of the steering means in such a way that the dynamic friction between the wheel (2) and the ground covering (3) changes back to static friction.

Abstract: The invention relates to a ground-based positioning system for determining a location of a mobile object (1), comprising a plurality of fixed ground stations (2a-2c) respectively comprising a transmitting and/or receiving unit (3a-3c), and at least one transmitting and/or receiving unit (5) that is arranged on the object, the transmitting mils being set up so transmit position signals and the receiving units being set up to receive the position signals transmitted by the transmitting units.

Abstract: The invention relates to a control device for aircraft comprising at least one aircraft undercarriage 4a, 4b, 4c arranged on an aircraft 1, which aircraft undercarriage has one or more undercarriage wheels 3, and comprising a control mechanism 5 which interacts with the aircraft undercarriage 4a, 4b, 4c and which is set up to turn the undercarriage wheels 3 relative to the longitudinal axis A of the aircraft 1. The control device has an alignment unit 6 which is connected to the control mechanism 5 and which is set up to control the turning of the undercarriage wheels 3 by means of the control mechanism 5 during at least one part of the landing or take-off phase I, II, III of the aircraft 1, in such a way that the running direction of the undercarriage wheels 3 is aligned in the direction of a fixed point 9, which may be a corrected fixed point situated below a fixed point 9 by a compensation angle.

Abstract: A control device for aircraft for reducing the turbulence and gust influences on the flying characteristics is designed to generate an additional incidence angle drive signal for control surfaces on surfaces which generate an air force, in particular wing and/or tailplane as a function of an instantaneous bank angle (?) and sideslip angle (?).
