Patent ID: 8095300

Claim:
A method for aiding the piloting of an aircraft, comprising: generating a speed profile which is associated with a ground rolling trajectory of the aircraft on an airport domain by carrying out the following steps: a) receiving said ground rolling trajectory which comprises a series of successive elements of the airport domain, each element representing a distinct and delimited part of said airport domain; b) entering, by an operator, first constraints relating to rolling of the aircraft on the airport domain; c) automatically determining, for each of said elements of said ground rolling trajectory, a plurality of values of maximum speed by taking account of said first constraints, and automatically selecting a minimum value from among said plurality of values of maximum speed as a maximum speed associated with the corresponding element; d) entering, by an operator, second constraints relating to the rolling of the aircraft on the airport domain, and which comprise at least time constraints, load factor constraints and jerk constraints; e) automatically determining said speed profile which is suited to each element of the ground rolling trajectory and which complies with a set of the maximum speeds and second constraints by taking account of the maximum speeds automatically selected in step c) and of said second constraints, said speed profile providing a variation of longitudinal speed as a function of the time which elapses during the rolling of the aircraft along said ground rolling trajectory; and f) providing the automatically determined speed profile to a pilot aiding unit; and said pilot aiding unit using the provided speed profile to aid the piloting of the aircraft, wherein step c) further comprises adjusting said maximum speed for at least one of the elements of the ground rolling trajectory, as a function of required accelerations and decelerations, and wherein the adjusting of said maximum speed comprises: if the length corresponding to the at least one element is not sufficient to attain a speed below the maximum speed corresponding to the at least one element during deceleration, adjusting the set of maximum speeds, beginning with a maximum seed at the end of the ground rolling trajectory and backtracking to the at least one element, and if the length corresponding to the at least one element is not sufficient to attain a speed above the maximum speed corresponding to the at least one element during acceleration, adjusting the set of maximum speeds, beginning with the maximum speed at the at least one element and going through the maximum speed at the end of the ground rolling trajectory.
