The invention proposes a simple system, with small space requirement, without hinge arms or sealing skirt, while providing secure and effective opening. To achieve this, the invention provides a door opening by a lateral guidance defining an integrated doubling-back kinematics, towards the interior then the exterior of the fuselage. An opening system of an emergency door (1) is positioned in an aircraft fuselage (2), the door and the fuselage comprising respective frameworks (11, 21) extending opposite each other. According to the invention, the system comprises a control handle (5) for rotating, combined with a bolt/latch pair, and an opening mechanism (30) equipped, in the upper corner areas (Zs) of the door (1), with a pivoting lever (6) hinged on an upper edge of the fuselage (2) and provided with guide tracks interacting with the bulk/latch pair and with a door attachment fitting (12), upper and lower rollers mounted in the lateral framework of the door (11c) in connection with the guide tracks (20s, 20i) mounted in the opposing fuselage framework (21c), the upper guide tracks (20s) being inclined rising towards the interior of the cabin (I) and the lower guide tracks (20i) being curved.
