Abstract
The invention relates to an aircraft control column, the control column comprising a first shaft and a control lever configured to rotate the first shaft about a first axis through a first angular range [α1; α3] via a mechanical joint having a primary reduction ratio, the control column comprising a braking device configured to brake the first shaft via a first transmission device having a secondary reduction ratio, the secondary reduction ratio being maximum for an angular position, the secondary reduction ratio increasing over the range [α1; α4] and then decreasing over the range [α4; α3] so as to obtain an overall reduction ratio that has a limited amplitude of variation over the first angular range [α1; α3].
