Abstract

The general area of the invention is that of methods for managing flight plans by an avionic system comprising a visualization device and a touch-sensitive interface. The visualization device displays a cartographic representation of the terrain flown over, aeronautical data and a flight plan composed of a set of segments connecting together certain aeronautical waypoints. The management method contains several steps, a first editing step activated by touch-sensitive designating of any point of the flight plan, a second modification of the flight plan step activated by a touch-sensitive movement, the end of the touch-sensitive movement triggering a movement or an addition or the removal of a waypoint. The method also makes it possible to easily manage the airways in order to incorporate them into a flight plan during modification.

Claims

1. Method for the management of a flight plan of an aircraft in flight by an avionic system comprising at least one visualization device and a touch-sensitive interface dedicated to this visualization device and implemented by means of touch-sensitive contacts, said visualization device displaying a cartographic representation of the terrain flown over by the aircraft, aeronautical data containing aeronautical waypoints and a flight plan composed of a set of segments connecting together some of said aeronautical waypoints,

wherein the management method contains at least two operations, a first “

editing”

operation activated by touch-sensitive designating of any point of a segment or of a waypoint of the flight plan and a second “

modification of the flight plan”

operation activated by a touch-sensitive movement starting on any point or on a first waypoint of the flight plan and ending in the vicinity of a second aeronautical waypoint, the end of the touch-sensitive movement triggering a movement of the first aeronautical waypoint towards a second waypoint or an addition of the second waypoint or the removal of the first waypoint, and in that, when the modification of the flight plan is a movement or an addition of an aeronautical waypoint to the flight plan, the visualization device displays the airways passing through the “

modified”

aeronautical waypoint.

2. Method for managing a flight plan according to claim 1, wherein the method contains a third “

insertion”

operation activated by touch-sensitive designating of an airway and triggering the display of all or some of the aeronautical waypoints of said designated airway.

3. Method for managing a flight plan according to claim 2, wherein the method contains a fourth “

selection”

operation activated by touch-sensitive designating of a third aeronautical waypoint known as the exit point of said designated airway and triggering the incorporation into the flight plan of the set of aeronautical waypoints situated between the modified waypoint and the point known as the exit point.

4. Method for managing a flight plan according to claim 1, wherein, when the touch-sensitive movement is at a predefined distance from a selectable aeronautical waypoint, an area of interest centered on said selectable aeronautical waypoint is displayed and in that, if the touch-sensitive movement comes to an end in said area of interest, the selectable aeronautical waypoint is selected.

5. Method for managing a flight plan according to claim 1, wherein the editing operation prompts the visualization device to show a menu containing four selection buttons, a first button for validation of the latest modification to the flight plan, a second button for cancellation of the latest modification to the flight plan, a third button enabling display of the previous modifications going backwards in time and a fourth button enabling display of the previous modifications going forwards in time.
