METHOD AND DEVICE FOR AIDING NAVIGATION FOR AN AIRCRAFT IN RELATION TO OBSTACLES
First Claim
1. Method of presenting zones at risk of collision with an aircraft, by use of a system of databases, a processor, an anticollision device and a viewing device, wherein, to display on the viewing device the zones at risk in relation to obstacles, the processor configured to carry out the steps of:
- acquiring obstacle data, the obstacle data corresponding to obstacles situated in a close displacement zone of the aircraft;
calculating a risk of collision with each of the obstacles situated in the close displacement zone;
calculating limits of the zones at risk of collision in the close displacement zone for each obstacle, based on a position of the obstacle, wherein the limits of the zones at risk of collision represent positions from which the anticollision device would produce collision alerts in relation to the obstacles if the aircraft were to steer towards the obstacle while maintaining instantaneous flight parameters; and
displaying the limits of zones at risk of collision.

Abstract
The invention relates to a method of presenting zones at risk for an aircraft comprising a system of databases, a processor, an anticollision device and a viewing device, wherein to display on the viewing device the zones at risk in relation to the obstacles, the processor carries out the steps of: acquiring obstacle data, the data corresponding to obstacles situated in the aircraft'"'"'s close displacement zone; calculating the risk of collision with each of the obstacles of the displacement zone; calculating the limits of the zones at risk of collision in the close displacement zone, these limits representing the positions from which the anticollision device might possibly produce collision alerts in relation to the obstacles if the aircraft were to steer towards the obstacle while maintaining the instantaneous flight parameters; and displaying the limits of zones at risk.
