An aircraft landing gear door comprises a rigid one-piece panel ( 14 ), hinged onto the aircraft structure by arms ( 18 ). The panel ( 14 ) is installed such that it pivots on the arms ( 18 ) in order to prevent any risk of contact between the panel ( 14 ) and the wheels ( 40 ) as the door opens and closes when the landing gear is extended, and a jack ( 34 ) automatically varies the angle Phi formed between these two parts, according to a predetermined kinematic law. A control system ( 28 ) automatically controls the jack ( 34 ) as a function of the jack ( 26 ) being actuated to control opening and closing of the door.
