Aircraft flight management system

RÉSUMÉ A process for managing air speed of an aircraft in flight. The method includes a first step of determining a point on the flight path at which it is theoretically possible to comply with a required time constraint by following a pre-established speed profile. In a second step, a speed is computed and a fresh speed profile is determined. This is obtained by determining speed corrections segment-by-segment from the point up to the last modifiable segment. The speed change in each segment is restricted to a maximum value. The new speed is computed on the basis of the curve showing the flight time t as a function of the speed V. This curve is approximated by a curve satisfying an equation with three coefficients (C1, C2, C3): V=c 1 /t+c 2 /t 2 +c 3 /t 3 Compliance with time constraints are ensured by this method while meeting the requirements of the pilot and air traffic controllers.
