Abstract: A process and system are disclosed for representing flight guiding information for an aircraft. A spatial representation of the air space with at least one horizon and the previously calculated flight path of the aircraft is represented by means of video equipment. The representation of the previously calculated flight path includes the previously calculated position and previously calculated attitude of the aircraft at different moments in time. The previously calculated flight path is represented by at least two bodies which extend along the flight path and of which at least one is represented to the left of the flight path and at least one is represented to the right of the flight path.

Abstract: In a method of detecting a collision risk and preventing air collisions, it is proposed that probabilities should be calculated for the likely presence of one's own aircraft in predetermined sectors at a number of selected times (probabilities of presence) and these probabilities for one's own aircraft and those for other objects should be used to calculate the probabilities of one's own aircraft and at least one of the other objects being present simultaneously in a given sector (probabilities of collision) for the predetermined sectors and selected times.

Abstract: In a process for depicting objects using an image reproduction device, data that describe the form and position of objects are fed into at least one image memory. The data are read out line by line and, along with other data describing the other properties of the objects, processed to form video signals which are fed to the image reproduction device.
