Landing assistance method and system associated with a display device of an aircraft

A landing assistance method associated with a display device of an aircraft, the display device configured to display a flight and navigation symbology on a display zone, the display zone having a coordinate system, which includes an abscissa axis indicating a yaw angle relative to a zero yaw reference line and an ordinate axis indicating a pitch angle of the aircraft relative to a zero pitch reference line,

• wherein the method comprises:
• an acquisition step, implemented by an acquisition module, involving acquiring environment data and current flight parameters of the aircraft, at least including an attitude, an altitude, a three-dimensional position and one heading parameter;
• a symbology generating step, implemented by a symbology generating module, involving generating a flight and navigation symbology to be displayed on the display device from at least the current flight parameters;
• a land topography generating step, implemented by a land topography generating module, involving generating a synthetic representation of a land topography of terrain overflown by the aircraft from at least the attitude, the heading, the three-dimensional position and the environment data;
• and
• a transmission step, implemented by a transmission module, involving transmitting a signal to the display device that represents the flight and navigation symbology and the synthetic representation;
• wherein the symbology generating step comprises at least one sub step of determining the position of a mock up, implemented by a mock up position determination sub-module, involving determining a display position of a mock-up of the aircraft on the display zone, the position of the mock up determined so that the mock-up is displayed at a predetermined non-zero positive pitch angle relative to a median line of the display zone, wherein the median line is parallel to the abscissa axis,
• wherein the land topography generating step comprises a sub step of generating a terrain zone, implemented by a terrain zone generating sub-module, involving generating a terrain zone configured to be displayed at the bottom of the display zone when the aircraft has a first pitch angle that is higher than an upper pitch angle that can be displayed on the display zone, wherein in an absence of the terrain zone generating step, the first pitch angle would cause only sky to be displayed on the display zone without the terrain zone displayed at the bottom of the display;
• and the land topography generating step comprises a sub step of generating a sky zone, implemented by a sky zone generating sub-module, involving generating a sky zone configured to be displayed at the top of the display zone when the aircraft has a second pitch angle that is lower than a lower pitch angle that can be displayed on the display zone, wherein in an absence of the sky zone generating step, the second pitch angle would cause only a terrain to be displayed on the display zone without the sky zone displayed at the top of the display.
