1. A system for remotely closing and opening a door provided for an access opening in a fuselage of an aircraft, the door comprising:
a door leaf,
a frame delimiting the access opening and an articulated arm, the frame being rigidly connected to the fuselage,
the door leaf being configured to be alternately in a closed position when the door leaf is closing the access opening and an open position when the door leaf leaves the access opening open,
the articulated arm comprising a first end articulated with the door leaf and a second end articulated with the frame so that the door leaf remains parallel with itself when moving from the open position to the closed position and vice versa,
a locking mechanism configured to alternately lock and unlock the door leaf when the door leaf is in the closed position,
the locking mechanism comprising a locking lever having one end that is rotatably mounted on the door leaf about a rotation axis perpendicular to the door leaf, the locking lever being configured to be alternately in a locking position in which the locking mechanism locks the door leaf and an unlocked position in which the locking mechanism is not locking the door leaf, wherein the system comprises:
a closing and opening device comprising a first closing and opening module configured to be removably fastened to the first end of the articulated arm and a second closing and opening module intended to be removably fastened to a structure rigidly connected to the frame,
the second closing and opening module being configured to alternately pull the first closing and opening module towards itself so as to bring the door leaf into the closed position and to move the first closing and opening module away from itself so as to bring the door leaf into the open position,
a locking and unlocking device configured to be removably fastened to the articulated arm, the locking and unlocking device being configured to move the locking lever alternately into the unlocked position to unlock the door leaf and into the locked position to lock the door leaf,
a control device configured to transmit commands for closing or opening the door leaf to the closing and opening device and commands for locking or unlocking the door leaf to the locking and unlocking device, as a function of commands transmitted remotely to the control device by a user.
