Units are to be provided with at least two independent means for communicating orders from the navigating bridge to the position in the machinery space or control room from which the engines are normally controlled, one of which should provide visual indication of the orders and responses both in the engine room and on the navigating bridge. Consideration is to be given to providing a means of communication to any other positions from which the engines may be controlled.
