1. A force application device for a control column for an aircraft, the control column comprising a first shaft, a second shaft and a control lever configured to rotatably drive the first shaft about a first axis and the second shaft about a second axis, the force application device comprising:
a first force feedback member configured to exert a resistive force opposing the rotation of the first shaft about the first axis and
a second force feedback member configured to exert a resistive force opposing the rotation of the second shaft about the second axis,
a common braking device comprising a casing, a first braking member and a second braking member, and wherein at least part of the first and second braking members are coaxial and rotatably mounted in the casing and are configured to cooperate respectively with the first shaft and the second shaft so as to brake them, simultaneously.
