Abstract

A piloting device for piloting an aircraft comprises a first and a second control stick mounted movable on a support. The device comprises a priority selection module configured to switch the first and second control sticks between a piloting configuration and a non-piloting configuration. The device further comprises a detection system for detecting the positions of the first and second control sticks; a first and second actuation system configured to generate respective first and second forces on the respective first and second control stick; and a control module configured to control the actuation system of the control stick which is in a non-piloting configuration such that the positions of the control sticks are identical.

First claim

What is claimed is:

1. A piloting device for piloting an aircraft comprising:
a first control stick and a second control stick, each mounted on a support,
each of the first and second control sticks being movable in relation to the support, between a plurality of positions around a neutral position in at least one degree of freedom,
each of the first and second control sticks being configurable between a piloting configuration, in which said first or second control stick is configured for piloting the aircraft by sending a trajectory command to a control unit, and a non-piloting configuration, in which no trajectory command from said first or second control stick is taken into account by the control unit;
a priority selection module configured to switch the first control stick between the piloting configuration and the non-piloting configuration, the selection module being configured to switch the second control stick to the non-piloting configuration when the first control stick is in the piloting configuration and to the piloting configuration when the first control stick is in the non-piloting configuration;
a detection system for detecting the position of the first control stick and the position of the second control stick;
a first actuation system configured to generate a first force on the first control stick according to the degree of freedom;
a second actuation system configured to generate a second force on the second control stick according to the degree of freedom;
a control module configured to control the actuation system of the first or second control stick which is in the non-piloting configuration, such that the position of said first or second control stick in the non-piloting configuration and the position of the first or second control stick which is in the piloting configuration are identical; and
at least one control system for controlling the selection module, the control system being configured to be operated by a first or second pilot to control the selection module, so as to switch the first control stick between the piloting configuration and the non-piloting configuration;
the control system further comprising at least two individual control elements, each of the first and second control sticks comprising an individual control element,
each individual control element being an individual button, the selection module being configured to switch the first control stick to its piloting configuration when the individual button of the first control stick is selected by the first pilot,
the selection module being configured to switch the first control stick to its piloting configuration when the individual button of the first control stick is held down by the first pilot, the selection module being further configured to switch the first control stick to its non-piloting configuration when the individual button of the first control stick is released.

2. The piloting device according to claim 1 , wherein the control system further comprises at least two individual control elements, each of the first and second control sticks comprising an individual control element.

3. The piloting device according to claim 2 , wherein each individual control element is an individual button, the selection module being configured to switch the first control stick to its piloting configuration when the individual button of the first control stick is selected by the first pilot.

4. The piloting device according to claim 3 , wherein, when the individual button of the first control stick is held down by the first pilot for a duration greater than a duration threshold, the selection module is configured to keep the first control stick in its piloting configuration.

5. The piloting device according to claim 1 , further comprising a priority indication system configured to output a signal representative of the configuration of at least one control stick among the first control stick and the second control stick.

6. The piloting device according to claim 5 , wherein the priority indication system comprises at least one indicator light, the signal being a light signal visible to at least one of the first or second pilot, indicating the current configuration of at least one of the first control stick and the second control stick.

7. The piloting device according to claim 5 , wherein the priority indication system further comprises a vibrator, the signal being a vibration perceptible by at least one of the first or second pilot and indicating that the configuration of each of the first and second control sticks has been changed.

8. A piloting method for piloting an aircraft using the piloting device according to claim 1 , the method comprising:
configuring the first control stick in the piloting configuration and the second control stick in the non-piloting configuration, by the selection module;
moving the first control stick according to the degree of freedom, by the first pilot;
controlling of the second actuation system by the control module, to generate a second force on the second control stick according to the degree of freedom so that the position of the second control stick and the position of the first control stick are identical;
switching, by the selection module, the first control stick to its piloting configuration when the individual button of the first control stick is held down by the first pilot; and
switching, by the selection module, the first control stick to its non-piloting configuration when the individual button of the first control stick is released.

9. The piloting method according to claim 8 , the method comprising an actuation of the control system to switch the first control stick to the piloting configuration and the second control stick to the non-piloting configuration, said actuation of the control system being carried out by the first or second pilot.

10. The piloting method according to claim 9 , wherein the control system comprises a shared control element, the shared control element being a shared button, the selection module switching the first control stick from either its piloting or its non-piloting configuration to the other when the shared button is selected by the first or second pilot.

11. The piloting method according to claim 9 , wherein the control system comprises at least two individual control elements, each of the first and second control sticks comprising one of the at least two individual control elements, each of the at least two individual control elements being an individual button, the selection module switching the first control stick to its piloting configuration when the individual button of the first control stick is held down by the first pilot, the selection module switching the first control stick to its non- piloting configuration when the individual button of the first control stick is released.

12. The piloting method according to claim 9 , wherein the control system comprises at least two individual control elements, each of the first and second control sticks comprising one of the at least two individual control elements, each of the at least two individual control elements being an individual button, the selection module switching the first control stick into the piloting configuration when the individual button of the first control stick is selected by the first pilot, the first control stick being kept in the piloting configuration when the first control stick is held down by the pilot for a duration greater than the duration threshold.

13. The piloting device according to claim 1 , further comprising at least one control system for controlling the selection module, the control system being
