Method for displaying the geographical situation of an aircraft

摘要

The general field of the invention is that of methods for displaying the geographical situation of an aircraft in flight on a visual display device. The geographical situation comprises a cartographic representation of the terrain flown over by the aircraft. Said geographical situation comprises two main display modes, known as “Arc” and “Rose”. The switch from the first mode to the second mode is made at least by means of a first step of selecting a model representing the position of the aircraft at the current time and arranged in the first mode and a second step of moving said model towards the position occupied in the second mode. The movement of the model causes the movement of the cartographic representation of the terrain being flown over, the steps of selection and movement being accomplished using a human-machine interface, which can be a graphic cursor control device or a touch-sensitive interface.

1. A computer-implemented method comprising:
displaying a geographical situation of an aircraft in flight on a visual display device using a first display mode, the first display mode including a symbol representing the aircraft, and the symbol being displayed in the first display mode as being situated at a first position that is at a bottom of a cartographic representation of terrain flown over by the aircraft in a space occupied by the aircraft at a current time; displaying the geographical situation of the aircraft in flight on the visual display device using a second display mode, the second display mode including the symbol representing the aircraft, and the symbol being displayed in the second display mode as being situated at a second position that is at a center of the cartographic representation of the terrain flown over by the aircraft in the space occupied by the aircraft at the current time; switching between displaying the first display mode and displaying the second display mode, wherein the first and second display modes are not displayed simultaneously, wherein the switching is performed in response to a set of operations being performed, and wherein the set of operations includes:
selecting the symbol, wherein the symbol situated at the first position is selected when the first display mode is being displayed and wherein the symbol situated at the second position is selected when the second display mode is being displayed,displaying a path between the first position associated with the first display mode and the second position associated with the second display mode, andmoving the symbol along the path between the first position and the second position, wherein the moving of the symbol causes a moving of the cartographic representation of the terrain flown over by the aircraft; and ceasing the displaying of the path between the first position and the second position, the ceasing of the displaying of the path between the first position and the second position being performed after performance of at least one of:
the moving of the symbol along the path between the first position and the second position, orthe switching between displaying the first display mode and displaying the second display mode.
