Abstract
A method assisting in navigation of aircraft following a flight plan subject to time constraints comprises: determining a minimum speed profile, a maximum speed profile, and minimum and maximum times of passage; determining, for each constraint of index i, a restricted interval and a required interval; the determination made by a first iterative computation, i being decremented from n−1 to 1 and comprising: determining a required interval of index i enabling the aircraft to observe a restricted interval of index i+1 by flying at a speed profile between the minimum and maximum speed profiles, the restricted interval of index i+1 determined on the preceding iteration for an iteration of index between 1 and n−2, or from the time constraint of index n for the iteration of index n−1; and determining a restricted interval of index i from the intersection of the time constraint and the required interval of index i.
