Abstract
A method for assisting in the piloting of an aircraft to observe a required time of arrival at a waypoint during a flight according to a predetermined flight plan comprising a nominal speed profile, comprising at least two flight segments, comprises the steps of determining an effective speed profile of the aircraft, and controlling by a guidance computer of the aircraft according to the effective speed profile. The step of determining an effective speed profile comprises the substeps of computing, for each segment of the nominal speed profile, a corrective term that is a function of a correction coefficient common to all the segments of the nominal speed profile, and computing, for each segment of the effective speed profile, a setpoint speed equal to the sum of a nominal speed of the nominal speed profile and of the corrective term.
