Abstract

The general field of the invention is that of viewing systems of the synthetic vision type SVS, for a first aircraft, the said system comprising at least one cartographic database of a terrain, position sensors, for the said aircraft, an air traffic detection system calculating the position and the danger rating of at least one second aircraft exhibiting a risk of collision with the said first aircraft on the basis of data originating from sensors or systems such as TCAS or ADS-B, an electronic computer, a man-machine interface means and a display screen, the computer comprising means for processing the various items of information originating from the database, sensors and interface means, the said processing means arranged so as to provide the display screen with a synthetic image of the terrain comprising a representation of the said second aircraft. The said representation comprises a first symbol representing in a stylized manner the said second aircraft and a second symbol, situated to the right of the first symbol when the second aircraft is facing towards the first aircraft and situated to the left of the first symbol when the second aircraft is facing away from the first aircraft

Claims

1. Viewing system of the synthetic vision type SVS, for a first aircraft, the said system comprising at least one cartographic database, of a terrain position sensors for the said aircraft, an air traffic detection system (605) calculating the position and the danger rating of at least one second aircraft exhibiting a risk of collision with the said first aircraft on the basis of data originating from reconnaissance sensors, an electronic computer, a man-machine interface means and a display screen, the computer comprising means for processing the various items of information originating from the database, sensors and interface means, the said processing means arranged so as to provide the display screen with a synthetic image of the terrain comprising a representation of the said second aircraft, wherein the said representation comprises a first symbol representing in a stylized manner the said second aircraft and a second symbol, situated to the right of the first symbol when the second aircraft is facing towards the first aircraft and situated to the left of the first symbol when the second aircraft is facing away from the first aircraft or vice versa.

2. The viewing system according to claim 1, wherein the representation of the second aircraft comprises a third symbol differing from the first symbol by its shape or by its colour and disposed symmetrically with the second symbol, in such a way that when the second symbol is to the right of the first symbol, the third symbol is to the left of the first symbol and vice versa.

3. The viewing system according to claim 2, wherein the first symbol comprises a horizontal segment and a fourth symbol representative of the trajectory of the second aircraft.

4. The viewing system according to claim 3, wherein the first symbol is an isosceles triangle with horizontal base and the second symbol and third symbol are circles of different colour or of different texture, disposed at the two ends of the base of the said triangle.

5. The viewing system according to claim 4, wherein, when the second aircraft is descending, then the tip of the triangle is directed downwards and when the second aircraft is climbing, then the tip of the triangle is directed upwards.

6. The viewing system according to claim 4, wherein, when the second aircraft is descending, then the triangle has a first texture or a first colour and when the second aircraft is climbing, then the triangle has a second texture different from the first texture or a second colour different from the first colour.

7. Viewing system according to claim 4, wherein the height of the triangle is proportional to the speed of climb or descent of the second aircraft, the triangle reducing to a simple segment when the second aircraft is holding level.

8. The viewing system according to claim 4, wherein the second symbol is coloured red and the third symbol is coloured green, these being representative of the position lights of the second aircraft.

9. The viewing system according to claim 4, wherein, when the second aircraft is at a shorter distance from the first aircraft than a safe distance, the second and third symbols flash.

10. Viewing system according to claim 4, wherein the first, second and third symbols are represented in conformal view, that is to say at the location that they occupy in the real landscape.

11. Viewing system according to claim 4, wherein the first, second and third symbols have a fixed size on the display screen.
