Abstract: A navigation system includes a display device displaying, on a cockpit pilot display unit, a set of indications including an aircraft symbol which illustrates the position of the aircraft and a map part which represents the airport and moves in relation to the aircraft symbol according to the current position of the aircraft in the airport, the aircraft symbol fixed on the cockpit pilot display unit in a centered position in a standard display. The system also has an actuating unit for deactivating the standard display to enable the aircraft symbol to be displaced on the cockpit pilot display unit, and an actuating unit for controlling a temporary displacement of the set of indications on the cockpit pilot display unit such that the aircraft symbol displayed moves away from the centered position.

Abstract: The invention relates to a device (1) comprising a set (2) of information sources for determining the active values of a plurality of parameter of an aeroplane, calculating means (3) for determining, by means of said active values, a first position corresponding to a position which is extrapolated from the nose of the aeroplane following a particular time interval from the current instant. The inventive device also comprises a database (5) provided with at least one pre-determined unauthorized zone of the airport, comparison means (6) for comparing said first position to said pre-determined unauthorized zone of the airport, and warning means (9) for emitting at least one warning signal if the first position is located in the unauthorized zone.

Abstract: A presentation device includes a searching device that searches for elements of an airport that are displayed on a display field of a screen. A verification device verifies, for each of the elements, whether the element forms part of a first group for which a main anchoring point is located inside a label zone or a second group for which the main anchoring point is located outside the label zone. A determining device determines, for the elements of the second group, a secondary anchoring point located at an intersection between an axis of the element and the label zone. For each element, a label for the element is presented on a screen. The labels associated with the first group are located at the main point and those associated with the second group are located at a secondary anchoring zone.

Abstract: The invention concerns a device (1) comprising means (2) for emitting periodically position data, means (3) for emitting inertial data, means (4) for determining the position of the mobile object upon each position data emission based thereon, and means (5) for determining the position of the mobile object between two successive emissions of position data, the time interval between two successive emissions being divided into time ranges of equal duration separated by intermediate times, the latter means (5) determining for each current intermediate time the position of the mobile object, based on its position at the preceding intermediate time and based on its movement during the time range delimited by the current and preceding intermediate times, movement which is calculated by means of the inertial date.

Abstract: The invention relates to a system comprising a display device displaying, on a cockpit pilot display unit (7), a set of indications (10) containing an aeroplane symbol (8) which illustrates the position of the aeroplane and a map part (9) which represents the airport and moves in relation to the aeroplane symbol (8) according to the current position of the aeroplane in the airport, the aeroplane symbol (8) being fixed on the cockpit pilot display unit (7) in a centered position (12) in a standard display. The inventive system also comprises actuating means for deactivating the standard display in such a way as to enable the aeroplane symbol (8) to be displaced on the cockpit pilot display unit (7), and actuating means for controlling a temporary displacement of the set of indications (10) on the cockpit pilot display unit (7) in such a way that the aeroplane symbol (8) displayed moves away from the centered position (12).

Abstract: Method and device for assisting in the navigation of an airplane on the ground at an airport. The device (1) comprises means (14) for transmitting an alarm signal, at least if an airplane position is not on a routing zone of the airport or if the orientation bearing-wise of the airplane on this routing zone does not correspond to a particular traffic direction.
