An aircraft comprising a first door and a second door, each being mobile between an open position and a closed position, and a maneuvering system. The maneuvering system includes an actuation mechanism, a first transmission chain configured to transmit the movements of the actuation mechanism to the first door, a second transmission chain configured to transmit the movements of the actuation mechanism to the second door. Such a maneuvering system uses a single actuation mechanism, which results in a simplification of the mechanism and a weight saving.

1. An aircraft comprising: a first door and a second door, each being mobile between an open position and a closed position about a fixed axis of a hinge, each hinge disposed on a structure of the aircraft and each door being mounted to one of the hinges, anda maneuvering system comprising: an actuation mechanism,a first transmission chain configured to transmit the movements of the actuation mechanism to the first door,a second transmission chain configured to transmit the movements of the actuation mechanism to the second door,a common transmission element present in the two transmission chains and configured to transmit to each transmission chain the movements of the actuation mechanism to the associated door, to link the first transmission chain to the second transmission chain and to synchronize the first transmission chain and the second transmission chain,where the actuation mechanism is a cylinder mounted to move rotationally about a first axis on a structure of the aircraft and which has a rod,where the common transmission element is a common vane mounted rotationally mobile about a third axis on the structure, the end of the rod being mounted rotationally mobile about a second axis on the vane,a first clutch configured to alternately assume a coupling position in which the first transmission chain transmits the movement of the actuation mechanism to the first door and a coupling position in which the first transmission chain does not transmit the movements of the actuation mechanism to the first door,a second clutch configured to alternately assume a coupling position in which the second transmission chain transmits the movements of the actuation mechanism to the second door and a uncoupling position in which the second transmission chain does not transmit the movements of the actuation mechanism to the second door,wherein the first transmission chain also comprises:a first arm of the first transmission chain having a first end mounted rotationally mobile about the third axis and a second end, anda second arm of the first transmission chain having a first end mounted rotationally mobile about a fourth axis on the second end of the first arm of the first transmission chain and a second end mounted rotationally mobile about a fifth axis on the first door, andwherein the second transmission chain also comprises:a first arm of the second transmission chain having a first end mounted rotationally mobile about a sixth axis on the vane and a second end,a second arm of the second transmission chain mounted rotationally mobile about a seventh axis on the structure and having a first end mounted rotationally mobile about an eighth axis on the second end of the first arm of the second transmission chain and a second end,a third arm of the second transmission chain having a first end mounted rotationally mobile about the seventh axis and a second end, anda fourth arm of the second transmission chain having a first end mounted rotationally mobile about a ninth axis on the second end of the third arm of the second transmission chain and a second end mounted rotationally mobile about a tenth axis on the second door. 2. The aircraft according to claim 1, wherein the first clutch and the second clutch are arranged either between the vane and one of the arms, or between two arms. 3. The aircraft according to claim 2, wherein the vane has a hole, the second end of the first arm of the first transmission chain has another hole, and the first clutch takes the form of a shaft which is housed in both said hole and said other hole in the coupling position. 4. The aircraft according to claim 2, wherein the second end of the second arm of the second transmission chain has a hole, the third arm of the second transmission chain has a hole, and the second clutch takes the form of a shaft which is housed in both said hole and said other hole in the coupling position. 5. The aircraft according to claim 1 further comprising, for each transmission chain, an abutment against which an element of said transmission chain comes to bear when the door concerned is set to the open position by the actuation mechanism. 6. The aircraft according to claim 1, wherein each door has a structure in which at least one tread is incorporated. 7. The aircraft according to claim 1, wherein each transmission chain comprises a force limiting element.
