  • control device 60 pilots the orientation system I so as to place each deployed slat in the closed position before the translational displacement along the direction of stowage of said slats. Indeed, the stowage of the deployed slats is made only if the deployed slats occupy the closed or flat position.
  • control device 60 pilots the displacement system II, that is to say the displacement motors 12 for moving the slats deployed to ensure the translation of the slats along the direction of stowage while these slats are in the closed position.
  • control device 60 pilots the operation of the orientation motor 14 fitted to the deployed slat furthest from the head slat 3 a , to ensure at the start of the transition area Ev, its tilting and bring it into its open upright position at the end of the transition area Ev. Each next slat is successively stowed according to the same principle.
  • control device pilots the displacement system II and the orientation system I so that each slat in the transition area Ev follows a regular orientation stroke to switch from its open position to its closed position and conversely.
  • the displacement of the slats in the closed or flat position allows reducing the resistance to displacement relative to the wind.
  • the first of the slats stowed in the open upright position acts as a deflector for the wind.
  • the deployment of the slats in the closed or flat position allows a faster surface coverage compared to a deployment of the slats in the upright position followed by a pivoting of the deployed slats.
  • control device includes a calibration mode allowing the installation to position the slats 3 in a defined position in order to identify their position.
  • control system pilots the motors 12 , 14 before any first use in order to place the different slats 3 in the stowed position with an upright orientation.
  • the identification of the position of the slats 3 in the stowed position is ensured by the contact sensors.
