A human machine interface linked to the throttle lever of an aircraft used to control the energy of an aircraft is disclosed. The HMI has upper part, which corresponds to the forward stroke of the lever, and a lower part, which corresponds to the rearward stroke of the lever. An upper shutter is positioned over the upper part, and a lower shutter is positioned over the lower part. A “cursor” acts as a visual representation in the HMI of the lever and its handle. The cursor moves forward or backward as the pilot acts on the lever/handle. The cursor indicates an ordered release of more or less aircraft energy, depending on its position on the display. The upper and lower shutters also indicate the ordered release of more or less aircraft energy, depending on the respective lengths of the two shutters. The HMI also includes a column in the display having a length symbolizing a current value in actual aircraft push or braking, depending on whether an aircraft push or braking has been ordered by releasing of more or less aircraft energy. The column changes in length as the actual aircraft push or braking changes. The cursor is further depicted in the HMI display as containing a memorizing button on the handle and a Go-Lever button on the lever below the handle.
