Patent ID: 8751070

Claim:
A method for aiding the piloting of an aircraft to climb to a safety altitude situated above an existing low-height flight trajectory, in which the safety altitude is a made safe altitude that avoids collision of the aircraft with surrounding terrain, the method comprising: a) determining, by a data processing device, the low-height flight trajectory, wherein the determination of the low-height flight trajectory by the data processing device includes determining: a lateral trajectory in a horizontal plane, a vertical trajectory in a vertical plane, and a maximum slope for the vertical trajectory; b) guiding the aircraft, by a guidance device, along the low-height flight trajectory determined by the data processing device; and c) controlling the guidance device by a setpoint actuation and selection device, upon a climb command, to bring the aircraft to attain the safety altitude, by subjecting the aircraft to a climb mode in a vertical plane according to a climb slope, determined by the data processing device, which is always greater than the maximum slope of the vertical trajectory of said low-height flight trajectory, wherein the aircraft is guided along a climb trajectory in the climb mode in which the aircraft is always above the vertical trajectory of the low-height trajectory determined by the data processing device, while following the lateral path of the lateral trajectory of the low-height flight trajectory.
