Mr. J. F. Green, in an article on gyro failure (this Journal, 13, 78). draws. attention to a principle that is of direct importance whenever navigators are dependent, for their information, on an equipment which, though normally serviceable, can develop a gross error. His principle is the triplication of instrumentation: the agreement between the two supposed serviceable equipments is a control on the possible malfunctioning of the third.
