Abstract
The present invention relates to helicopter automatic piloting equipment. The automatic piloting device for helicopter acts on flight controls of the helicopter that are affected by mechanical play by means of a group of mechanically irreversible rams termed series rams with fast response and short stroke, placed in series on the flight controls. According to the invention, the device comprises at least one detector for detecting direction of variation of the displacement instructions of the series rams and a play compensator adding to the instruction, as a function of the latter's direction of variation, a corrective term dependent on the mechanical play affecting the flight control equipped with the series ram concerned.
