Abstract: A device for displaying a document includes a display screen, a human-machine interface, a first memory zone and at least one second memory zone separate from the first memory zone. The zones are configured to contain similar information. A processor is configured to execute a first process and at least one second process when a display request is received via the human-machine interface. Those processes include respectively reading first information in the first memory zone and second information in the second memory zone. That information corresponds to the display request. The processes also include respectively producing a first display layer and a second display layer associated with the display screen, the first display layer and the second display layer being displayed on the display screen superimposed.

Abstract: Method and device for automatically managing air operations requiring a guarantee of navigation and guidance performance of an aircraft. The device for automatically managing at least one air operation comprises activatable monitoring of the air operation, a computation unit configured to automatically calculate an anticipated activation point as a function of the application point of the air operation, this anticipated activation point being defined upstream of the application point in the direction of flight of the aircraft, and an activation unit configured to automatically activate monitoring and a display when the aircraft reaches, during its flight, the anticipated activation point.

Abstract: The device includes a receiving unit for receiving at least a start point of an unspecified termination segment, an orientation of the unspecified termination segment and a start point of a following segment, a first computation unit for calculating a median plane passing through the start point of the following segment and perpendicular to this following segment, a second computation unit for calculating an operational distance, called calculated operational distance, as a function of the position of the start point of the unspecified termination segment relative to the median plane, using geometric data, and a transmission unit for providing at least one user means with the calculated operational distance.

Abstract: This relates to a method and device for constructing a vertical profile for an aircraft descent and/or approach. The construction device comprises a data-capture unit configured to provide, for at least one of a plurality of parameters, a value relating to a user strategy. A construction unit is configured to automatically construct a vertical profile for an aircraft descent and/or approach, using the value thus provided.
