Method for managing the thrust and velocity of an aircraft

A method for managing the thrust and velocity of an aircraft, the method being implemented by a flight management system located on board the aircraft and comprising electronic circuitry, the method comprising, for at least one flight phase of the aircraft comprising a variation in altitude within a defined range of altitude values:

• receiving a thrust and velocity profile comprising, for each altitude slice among a plurality of altitude slices of the defined range of altitude values, a target thrust value and a target velocity value;
• calculating, depending on the thrust and velocity profile and on a current altitude of the aircraft, a thrust setpoint and a velocity setpoint;
• transmitting the thrust setpoint to an engine control system (206) located on board the aircraft and configured to act on an engine (207) of the aircraft depending on the thrust setpoint;
• and
• transmitting the velocity setpoint to a flight control system located on board the aircraft and configured to act on flight control surfaces of the aircraft depending on the velocity setpoint.
