Abstract: A buoyancy system (10) for an aircraft (1), the buoyancy system (10) being provided with at least one inflatable float (15). The buoyancy system (10) has at least one inflator (25) and at least one actuator (30) interposed between said inflator (25) and a float (15), said actuator (30) having a cylinder (35) and a rod (40) partially received in said cylinder (35). Said rod (40) is secured to a piston (50) defining a first chamber (61) within said cylinder (35) and in fluid flow communication with the inflator (25), and a second chamber (62) within said rod (40) and in fluid flow communication with said float (15), and said piston (50) has a channel (63) to put the first chamber (61) into fluid flow communication with the second chamber (62), said deployment device (20) having a shutter (70) for shutting said channel (63).
