A method and device for automatically determining a speed profile with speed levels for an aircraft. The device includes a calculation unit which is configured for determining a speed profile (P1) which is such that, from upstream to downstream, the speed (V) is maintained at a speed constraint (V1) imposed at a waypoint (B1), up to said waypoint (B1), then a deceleration (T2) is performed from this waypoint (B1) up to an optimum speed (Vopt), said optimum speed (Vopt) being maintained up to another deceleration (T4) ending directly at a downstream speed limit (V2) reached at a given altitude level (A2). |
