Abstract
Device and system for the automatic control of a helicopter.The automatic control device (6) comprises a vertical objective law (A) in respect of the pitching axis, which automatically determines a control command (UT1) for operating the tilting of the disk of main rotor of the helicopter, a speed limitation law (B) for limiting the airspeed of the helicopter with respect to at least one limit value, detection means (10) for automatically detecting whether the airspeed reaches the limit value, and toggling means (11) for, in order to select the objective law (A, B) whose control command (UT1, UT2) is used for the pitching axis, automatically toggling from the first law (A) to the second law (B), when the detection means (10) detect that the airspeed has reached the limit value.
