Abstract
Disclosed is a system for generating a controlled speed for an aircraft along a ground trajectory. The system provides for receiving a ground trajectory of the aircraft and the speed profile of the aircraft. An interpolated speed of the aircraft is calculated on the basis of the ground trajectory, the speed profile and the current position; a weighting factor is calculated from an angular deviation, which is calculated from a measured current aircraft heading and the ground trajectory; an auxiliary speed is determined from the calculated interpolated speed; and the determined auxiliary speed is multiplied by the weighting factor to generate the controlled speed.
