The invention claimed is: 1. A device for issuing an authorization signal corresponding to an authorization to act on the operating conditions of at least one engine of an aircraft, said device comprising: first means for determining particular parameters relating to the aircraft, including the pos
The invention claimed is: 1. A device for issuing an authorization signal corresponding to an authorization to act on the operating conditions of at least one engine of an aircraft, said device comprising: first means for determining particular parameters relating to the aircraft, including the position of a throttle lever controlling the fuel supply to the engine; and second means for determining, on the basis of said particular parameters, whether the aircraft is in a state authorizing an action on the operating conditions of the engine, and for issuing, as appropriate, a corresponding authorization signal, wherein said device furthermore comprises: third means for determining whether the following conditions are realized: a) another engine of the aircraft is faulty; b) another engine is cut off; and c) an authorization signal is issued for another engine; and fourth means for disabling the issuing of an authorization signal, when said third means detect the realization of one at least of said conditions a), b) and c). 2. The device as claimed in claim 1, wherein said second means issue an authorization signal, when at one and the same time: the height of the aircraft with respect to the ground is below a predetermined height; the output of the engine is above a predetermined output; and the position of the throttle lever is below or equal to a predetermined position. 3. The device as claimed in claim 1, wherein said second means issue an authorization signal, when the aircraft is on the ground and the engine is idling. 4. The device as claimed in claim 3, wherein said second means determine that the engine is idling, when at least the position of the throttle lever for said engine is below or equal to an idling position. 5. The device as claimed in claim 4, wherein said second means determine that the engine is idling, when moreover the position of a throttle lever for another engine of the aircraft is below or equal to a predetermined position. 6. The device as claimed in claim 3, wherein said second means determine that the aircraft is on the ground, when at least ground spoilers are extended or a main landing gear of the aircraft is compressed. 7. The device as claimed in claim 6, wherein said second means determine that the aircraft is on the ground, when moreover the height of the aircraft with respect to the ground is below a predetermined height or the speed of the wheels of the aircraft is above a predetermined speed. 8. A system for controlling at least one engine of an aircraft, said control system comprising at least: a throttle lever able to be actuated by a pilot of the aircraft, to control the fuel supply to the engine; and a means of monitoring and of regulating the engine, which is able to act on the operating conditions of said engine, wherein said system furthermore comprises at least one device such as that specified in claim 1, for issuing an authorization signal, and in that said monitoring and regulating means is formed in such a way as to be able to act on the operating conditions of said engine only if it has previously received of an authorization signal issued by said device. 9. An aircraft comprising at least one control system such as that specified in claim 8, for controlling at least one engine of said aircraft. 10. The control system as claimed in claim 8, wherein said monitoring and regulating means is able to act on the operating conditions of the engine, by modifying the flow rate of fuel of said engine or by cutting off said engine. 11. The control system as claimed claim 8, for controlling a plurality of engines of the aircraft, wherein said system comprises a plurality of assemblies associated respectively with said engines and each comprising a throttle lever, a monitoring and regulating means, and a device for issuing an authorization signal.
