METHOD AND DEVICE FOR TRANSMITTING ALERTS FOR FIELD AVOIDANCE BY AN AIRCRAFT WITH A ROTATING WING

摘要

The invention relates to a method and a device (50) for issuing an alert for the avoidance of terrain by a rotary wing aircraft (100) in which at least one web (N1, N2) of trajectories is produced. possible avoidance of said aircraft (100) to avoid a collision of said aircraft (100) with the relief (70) overflown. An alert is then triggered as soon as said raised relief (70) is at a distance from one of said sheets (N1, N2) of possible avoidance trajectories less than a predetermined distance (Mv). Said avoidance paths are determined from a predetermined avoidance maneuver and from the states of said aircraft (100), said predetermined avoidance maneuver being performed at a predetermined maximum power of said aircraft (100).
