The throttle control device controlling two engines of a same aerodyne which embodies the invention uses a drive mechanism mounted rotatably about a fixed axis and rotated by means of a servomotor controlled by a computer ensuring automatic flight velocity control for the aircraft, two levers respectively integral with two annular elements mounted rotatably about said axis, on both sides of the drive mechanism, two electromagnetic couplers respectively disposed between said annular elements and said drive mechanism, and two angular position sensors respectively associated with the two annular elements, these two sensors being respectively connected to the throttle control circuits of the engines of the aircraft. This system ensures the independence of the two levers and the level of safety required for automatic control of the aircraft.
