A method of enabling an autopilot (9) to cause a rotorcraft (1) to follow a path. At least one guide mode (G) relative to at least one progression axis (P, R, V, Y) of the rotorcraft (1) is selected by the rotorcraft pilot. Said selection causes the selected guide mode (G) to be inhibited (19) and causes a path setpoint (C) to be acquired (20) from the pilot of the rotorcraft (1) operating a manual control member (4) for controlling the progression of the rotorcraft (1). The path setpoints (C) relating to other guide modes (G) of the rotorcraft (1) that continue to be engaged are conserved in their initial states and the autopilot (9) adapts the commands relating to the progression axes (P, R, V, Y) relating to these other guide modes (G). |

1. A method of using an automatic flight control system for a rotorcraft having an autopilot that generates commands in predefined operating modes, the commands causing a modification to the behavior of the rotorcraft relative to at least one of the progression axes (P, R, V, Y) of the rotorcraft comprising at least pitching (P), roll (R), verticality (V), and yaw (Y), wherein the autopilot incorporates a path-maintaining function for the rotorcraft comprising at least one guide mode (G) of the autopilot for guiding the rotorcraft relative to at least one of said progression axes (P, R, V, Y) of the rotorcraft, in which the path-maintaining function comprises:
an acquisition request for acquiring at least one path setpoint defined by at least one flight parameter is issued by a person, said path setpoint relating to said at least one guide mode (G), and then as a result of the person driving at least one manual control member to cause a modification to the behavior of the rotorcraft relative to at least any one of said progression axes (P, R, V, Y), the autopilot generates:
an inhibit command whereby the autopilot inhibits said at least one guide mode (G) of the rotorcraft for which said acquisition request to acquire a path setpoint has been issued and relating to said at least one progression axis relative to which the behavior of the rotorcraft is being modified by the person; and an acquisition command whereby the autopilot acquires the value of said at least one flight parameter relating to said path setpoint to be acquired and applicable to said at least one progression axis from which the behavior of the rotorcraft is being modified by the person, said value being evaluated under the condition that said movement applied to the manual control member is interrupted, and said value on its own taking the place of the value of at least one said flight parameter acquired by the autopilot prior to the inhibit command, the path setpoints relating to the other guide modes (G) of the rotorcraft that have continued to be engaged and that relate to said other progression axes (P, R, V, Y) being conserved in their states prior to said person moving said at least one manual control member, the commands generated by the autopilot relating to all of the progression axes that continue to be engaged being adapted by the autopilot depending on the current state of progression of the rotorcraft on the basis of said conserved path setpoints and on the basis of said value taking the place of said at least one flight parameter for which said acquisition request was issued. |
