Abstract

The general field of the invention is that of synthetic vision type viewing systems SVS, for a first aircraft, said system comprising at least position sensors of said aircraft, an air traffic detection system calculating the position and the dangerousness of at least one second aircraft presenting a risk of collision with said first aircraft based on data obtained from recognition sensors, an electronic computer, a human-machine interface means and a display screen, the computer comprising means of processing different information obtained from the sensors and from the interface means. The system according to the invention also comprises a frequency synthesizer coupled to at least one loudspeaker, arranged so that, when the second aircraft is at a distance from the first aircraft that is less than a safety distance, the synthesizer generates an audible alarm representative of at least one of the parameters of said second aircraft. Furthermore, the display screen comprises a symbology representative of the operation or of the state of the frequency synthesizer.

Claims

1. Synthetic vision type viewing system SVS, for a first aircraft, said system comprising at least position sensors of said aircraft, an air traffic detection system calculating the position and the dangerousness of at least one second aircraft presenting a risk of collision with said first aircraft based on data obtained from recognition sensors, an electronic computer, a human-machine interface means and a display screen, the computer comprising means of processing different information obtained from the sensors and from the interface means, the system also comprising a frequency synthesizer coupled to at least one loudspeaker, arranged so that, when the second aircraft is at a distance from the first aircraft that is less than a safety distance, the synthesizer generates an audible alarm representative of at least one of the parameters of said second aircraft.

2. The viewing system according to claim 1, wherein the parameter of the second aircraft is either the type, the category or the size of the second aircraft or a sound that is characteristic of said aircraft.

3. The viewing system according to claim 1, wherein the parameter of the second aircraft is the relative speed of the second aircraft.

4. The viewing system according to claim 3, wherein, when the parameter is the relative speed of the second aircraft, the frequency of the audible alarm is modulated so as to simulate a Doppler effect.

5. The viewing system according to claim 1, wherein the display screen comprises a symbology representative of the operation or of the state of the frequency synthesizer.

6. The viewing system according to claim 5, wherein, when the screen displays a two-dimensional or three-dimensional representation of the space surrounding the first aircraft, the spatial boundaries between which an alarm is likely to be emitted are represented in a conformal view.

7. The viewing system according to claim 1, wherein, if several second aircraft present a risk of collision with the first aircraft, the computer comprises means for determining the second aircraft presenting the highest danger, the audible alarm being representative of said second aircraft.
