METHOD OF SECURING A CALCULATED FORECAST ROUTE FOR AN AIRCRAFT, CORRESPONDING COMPUTER SYSTEM AND PROGRAM

摘要

A method of securing an aircraft route prediction of potential threats associated with geographic coordinates, wherein the predicted route comprises geographic coordinates of waypoints (M1, M2, M3), two waypoints successive means defining a predicted road section of ends said two points of passage, said method comprising the steps according to which: a first risk detection step is performed as a function of at least the geographical coordinates of the ends of each section between two crossing points and threats to identify potentially at risk couples (stump, threat); said method being characterized in that, each section being cut into segment segments, a second risk detection step is then performed for each pair, for, as a function of at least the geographical coordinates of the segments of the torque section and 'at least the geographical coordinates of the threat of the couple, determine whether the said threat is confirmed as presenting a risk of collision with the said section.
