Method for the temporal display of the mission of an aircraft
The general field of the invention is that of methods for displaying the steps of a mission or of a flight plan of an aircraft on a screen of a display device. The different steps of the method are displayed in a first graphical window comprising a time scale or “timeline”, the different steps being displayed opposite the schedule corresponding to their accomplishment. This window can be associated with a cartographic view of the flight plan. It can comprise a “magnifier” function.
1. A method for displaying stages of a mission of an aircraft on a screen of a display device, the method comprising:
displaying a first graphical window comprising a time scale, the stages being displayed in the time scale, the stages being displayed opposite a schedule of time indications in the time scale, the schedule of time indications corresponding to accomplishment of the stages,
wherein a length of the time scale is longer than a length of the first graphical window such that the first graphical window displays only a part of the time scale, the displayed part of the time scale being imposed by a user of the display device,
wherein the first graphical window comprises a first symbol representing the aircraft, the first symbol being situated, in a standard operating mode, at a current time on the time scale,
wherein, when a current time is situated outside of the first graphical window, the first symbol representing the aircraft is displayed at a top of the displayed part of the time scale or at a bottom of the displayed part of the time scale, a predetermined action by the user on the first symbol automatically centering the time scale on the current time.
2. The method of claim 1 , wherein the first graphical window comprises a magnifier function for expanding the time scale by a predetermined factor within a predetermined time range centered on a time imposed by a user of the display device.
3. The method of claim 2 , wherein, with the mission being a flight plan and each stage corresponding to a waypoint of the flight plan, the method further comprises displaying a second graphical window, the second graphical window representing a cartographic view of said the flight plan, the second graphical window comprising a second symbol representing the aircraft, the second symbol being situated, in a standard operating mode, on the cartographic view at a current time.
4. The method of claim 3 , wherein the first graphical window and the second graphical window are disposed on the same display screen, juxtaposed with each other, or on different screens.
5. The method of claim 3 , wherein movement of the magnifier function results in movement of the second symbol on the cartographic view in such a way that a position of that second symbol is representative of a position that the aircraft would actually occupy at a time indicated by the magnifier function.
6. The method of claim 1 , wherein, with the mission being a flight plan and each stage corresponding to a waypoint of the flight plan, the method further comprises displaying a second graphical window representing a cartographic view of the flight plan, the second graphical window comprising a second symbol representing the aircraft, the second symbol being situated, in a standard operating mode, on the cartographic view at the current time.
7. The method of claim 1 , wherein the first graphical window comprises a magnifier function for expanding the time scale by a predetermined factor within a predetermined time range centered on a time imposed by the user of the display device.
