Said aircraft (10) comprises: a cell comprising a fuselage (12), a wing unit (14) and a tail unit (16); a main propulsion group (20) consisting of a motor (22) and a propeller (24); a flight control device (30) comprising electrical actuators (35), movable surfaces (31 to 34) and sensors (36); and an automatic piloting computer (40) which sends instructions to the main propulsion group and to the flight control device. Said unmanned aircraft further comprises a pair of auxiliary propulsion groups (51, 52), each auxiliary propulsion group comprising an electric motor, a propeller which is driven by the electric motor and a means for orienting the plane of the propeller relative to the cell, the piloting computer (40) being programmed to adjust an orientation angle and a rotation speed of the propeller of each auxiliary propulsion group in order to overcome a malfunction in the flight control device and/or the main propulsion group so as to control the path in all the axes, the unmanned aircraft thereby having increased reliability.
