Abstract: A device includes a current position unit for determining a current position of a aircraft, a mapping database, a navigation system, a current heading unit for determining the current heading of the aircraft, and a display system for displaying on a viewing screen, at least a partial map of the airport and, thereon, an aircraft symbol which is positioned at the current position and which is oriented in accordance with the current heading.

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 concerns a device (1) comprising means (2) for determining the current position of the aircraft, a mapping database (3), a navigation system (4), means (9) for determining the current heading of the aircraft, and a display system (6) for displaying on a viewing screen (8), a map at least partial of the airport and, thereon, an aircraft symbol which is positioned at said current position and which is oriented in accordance with the current heading.

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.
