Abstract
A device for the automatic control of a helicopter may include two objective algorithms associated with the collective axis, each of these algorithms automatically determining a command for operating the collective pitch of the blades of the main rotor of the helicopter. The device may also include two objective algorithms associated with pitching axis that function simultaneously and automatically determine a command for operating the tilting of the disk of the main rotor. A first selection device automatically selects the objective algorithm whose command is used for the collective axis, and a second selection made by the first selection device, the objective algorithm whose command is used for the pitching axis.
