Process for flying an aircraft in the “elevator speed maintenance mode”during altitude changes, in which for acquiring and/or maintaining a nominal speed it is supplied to the flight computer at the same time as the instantaneous speed of the aircraft, said computer producing the elevator control instruction, characterized in that a nominal speed is also simultaneously transmitted in continuous manner to the automatic thrust control member of the engines and in that the process is performed during two successive sequences, namely: a first sequence during which the elevator only receives a nose up instruction (on climbing) or a dive instruction (on descending) and the engines move to full thrust in the first case or to idling speed in the second and a second sequence, following the first, during which the real nominal speed is supplied to the elevator instruction computer and said same nominal speed increased (on climbing) or decreased (on descending) by a margin is supplied to the automatic thrust control member.

Process for flying an aircraft, during altitude changes, at a nominal speed within the known performance limits of the aircraft, said aircraft having an engine automation thrust instruction computer, a pilot rule computer and an elevator for autopilot control characterized in that the nominal speed is transmitted in a continuous manner to the engine thrust instruction computer with the process performed during two successive sequences, comprising: a first sequence during which the elevator only receives an instruction to put the nose up (on climbing) or dive (on descending) and priority is given to said elevator by transmitting to the engine automatic thrust instruction computer a nominal speed equal to or higher than the instantaneous speed of the aircraft on climbing, or equal to or below the instantaneous speed of the aircraft on descending, so that said thrust continuously increases on climbing or continuously decreases on descending until the maximum thrust is obtained in the first case and the minimum thrust in the second and a second sequence, following the first, during which the real nominal speed is supplied to the elevator instruction computer and said same nominal speed, increased (when climbing) or decreased (when descending) by a margin is supplied to the automatic thrust instruction computer.
