Abstract: A method and device for determining a plurality of performance indicators relating to the flight of an aircraft and an associated computer program product are disclosed. In one aspect, the method includes calculating a first performance indicator based on an estimated time of arrival of the aircraft at the arrival location, an estimated flight time of the aircraft from its take-off until its arrival at the arrival location, and an estimated amount of fuel consumed by the aircraft up to the arrival location. The method further includes calculating at least one other performance indicator among second and third performance indicators. The second performance indicator is calculated based on a time difference between the estimated arrival time and the intended arrival time. The third performance indicator is calculated based on a consumption difference between the estimated amount of consumed fuel and the intended amount of consumed fuel and an additional quantity.
