Abstract:
1. A device for signaling risks incurred by a craft on account of real or regulatory obstacles situated in its domain of progress, comprising: means for selecting a zone of deployment, means for considering various types of risk region of the selected zone of deployment, of which a first type of risk region consisting of regions inaccessible to the craft because of its capabilities of crossing at a time and/or of regulatory forbidden crossing regions, means for determining a second type of risk region of the selected zone of deployment, including the regions inaccessible to the craft after an adoption of a fallback trajectory profile envisaged in advance, and means for determining, in the selected zone of deployment, of two lateral regions of tight deployment, to a right and to a left with respect to a position of the craft and to a direction of a course that it follows, defined on a basis of a ground trace of the trajectory which would be traversed by the craft if it performed a change of direction of a magnitude determined during a turn with radius of curvature also determined.
