Process and device using a flight management system (FMS) for aiding aerial navigation. To facilitate the task of the pilot, the FMS carries out a dialogue with the pilot via a data display and input console (MCDU), which displays a list of tasks to be executed in the form of a succession of selectable and activatable main zones. Each zone corresponds to a task, executed via the console, and when the task has been executed (validation key actuated by the pilot), the list of tasks is redisplayed, with the zones for which tasks have been executed and validated appearing in a different color from other zones. The zones preferably appear in duplicate when there is a co-pilot, so that it is easy to see which tasks have been performed and by which pilot, and which tasks remain to be performed.

Method and device for inputting and controlling flight data

A process and device for assisting aerial navigation. The system affords the pilot of the aircraft greater knowledge regarding the situation which results from automatic decisions of a flight management system. A central zone is displayed on a viewing screen which represents the overall use of the navigation instruments. Peripheral zones of the screen represent the individual instruments with a visible plot of the relationship between the central zone and a particular peripheral zone when the latter corresponds to a navigation instrument actually being used. For example, the central zone is a disk whose diameter represents the mean error in position given by the use of the various instruments and the visible plots of relationship are color radial sectors which extend between the central zone and certain peripheral zones. The names of the instruments are indicated in the peripheral zones.

Process and device for aiding aerial navigation, with display of navigation instruments used

The disclosed method is implemented by a system aboard an aerodyne comprising a processor, a terminal and memories in which there are stored all the information necessary for the carrying out of a flight, the system being connected to the other on-board electronic equipment. In order to define a new flight plan to meet a new situation caused by an event, the method comprises: the interpretation of the event to determine the corrective actions to be undertaken given the context in which the aerodyne is located, the analysis of the possibilities of reconfiguring the flight plan that correspond to the corrective actions, according to predetermined and modifiable criteria, the selection of the flight plan solutions that meet the predetermined criteria, and the presenting of these flight plan solutions in association with the significant parameters that have served as the grounds for their selection.

Process and device for aiding aerial navigation, facilitating the input

A method which uses a terminal comprising a processor, a screen and a keyboard, comprises step by step breakdown of all the information ('checklist') to be structured into subsets and identification of their structure, grouping together by similar structures of the subsets into objects ('blocClist', 'tiCL', 'tiblocCL', 'remark', 'item', 'Sdeb', 'verif', 'Sfin'), input into the terminal of each object, in the form of a graphical symbol representing a node, and of the characteristics thereof, input into the terminal of link type symbols connecting two objects indicating a hierarchical include relation between two objects, translation by the terminal of the graph thus derived into a structure model expressed in a computer language and monitoring of the consistency thereof. The method applies notably to the management, by an on-board computer in an aircraft, of the lists of tasks to be performed during the phases of piloting.
