Method and system for arming/disarming an aircraft door slide and implementation assembly

A method for arming/disarming a slide of an airplane door linked with a cabin floor of the airplane, in which—in arming mode called ARM—the door is lowered into closed position to engage first connection parts of two releasable mechanisms with elastic centering element on second connection parts of the mechanisms, respectively secured to the door and to the cabin floor;

• the first parts are locked on the second parts of the mechanisms by a misalignment of respective impressions following a simultaneous rotational driving of the first connection parts by a translation according to a blocking kinematic triggered by a single command for attaching locking/unlocking means of the first connection parts to a girt bar and actuated by an energy source, other impressions of the first parts being then aligned releasably;
• in case of emergency exit, the slide attached only to each mechanism is unfurled and inflated;
• and—in a disarming mode called DISARM—said mechanisms are unlocked by a mechanical driving of reverse translational and rotational kinematic which unlocks the first parts from the second parts by an alignment of respective impressions and locks the first parts to the door by a misalignment of the other impressions, then in lifting the door (1) to uncouple the parts of the mechanisms before preceding to open it.
